1 Primary Open Angle Glaucoma in the Young Age , Ahmed Mostafa Abdelrahman and Rana H Amin
Primary open angle glaucoma in the young age is known as The Juvenile open angle glaucoma (JOAG) which is a form of primary open angle glaucoma (POAG) that presents with elevated IOP in-traocular pressure between the ages of 4 and 35 years (up to 40 years of age in other reports). Most cases are inherited as an auto-somal dominant trait, and therefore, most families may be aware of their risk of developing this condition. In spite of IOP elevation, it doesn’t usually cause corneal enlargement or Haab's Striae; rather, progressive myopia may continue [1]. The mean age at diagnosis was 26 ± 9.8 years and the estimated prevalence of JOAG ranges from 0.38 to 2 in 100,000 in individuals between 4 and 20 years of age [2].
2 Outbreak of Corona Virus, Ocular Involvement and Scenario in Nepal , Raju Kaiti, Ranjila Shyangbo, Manish Dahal and Bishal Hamal
Coronavirus disease (COVID-19) originating in the Chinese city of Wuhan has rapidly emerged as a global health threat. It is an-ticipated that over 186 countries have been affected, with Nepal being one of the countries at major risk. Nepal reported its first case on 13th January 2020. The novel corona virus 2019 (2019-nCoV) has sparkled global concern but the route of its transmission has not yet been elucidated fully. It is believed to be mainly respiratory. There have been anecdotal reports of ocular transmission. No cases of ocular transmission has been reported in Nepal. Nepal government lacks enough kits for rapid screening. Till date, Nepal is only one country marked Green for Corona virus. It is important for government to to be responsible enough to suppress the cases of COVID-19, prevent transmission and to make necessary arrangements, identify, diagnose cases, isolate and quarantine
3 Black Cataract and SICS: A Safe Surgery with Excellent Outcome , Prasanth Gireesh, Abdulmajeed Alharbi and Poulomi Das
Black cataract is quite common in developing country like India. The biggest problem while dealing with these is, the nucleus is quite hard to break by phaco energy. As a result, post op Striate keratitis is very common. Along with intra op complications are also pretty high for these. On the other hand, SICS is quiet safe surgery when dealing with intra op and post op complications. Here, we are reporting a case report of, how black cataracts can be safely removed by SICS technique. Both intra op and post op complications are less here compared to phaco. Though chances of healing of wound will take a few days longer compared to phaco, but we believe, the odd s are favorable here for SICS surgery.
4 Novel Trends in Screening for Diabetic Retinopathy , Abdulmajeed Alharbi
Diabetic retinopathy screening is the first step to take for treating diabetic patients in a large population. We don't know as of now, how many people are actually suffering from Diabetic Retinopathy. The actual no of patients are much more and it's increasing daily. Because of the slow progress nature of the disease, patients themselves don't know for years, that they are suffering from diabetes. Once it starts affecting all the microvascular structures of body, the effect becomes more prominent. Eye and kidney are one of the most important organs to get affected in diabetes. A no of different tests are getting done in community level to detect DR in early stage. With the progress of telemedicine and wide community awareness it's becoming easy to detect and screen patients in early stages and treat them.
5 Clinical Characteristics and Visual Rehabilitation in Keratoconus Patients Presented at a Tertiary Eye Care Institute in Uttar Pradesh (India) , Jude Nnoruga, Mosaib Omaer, Ashi Khurana and Lokesh Chauhan
Purpose: To assess the clinical characteristics and visual rehabilitation in Keratoconus patients. Methods: Medical records of consecutive patients diagnosed of Keratoconus presented at a tertiary eye care institute during September 2009 to December 2017 were reviewed retrospectively. Demographic details (age, gender, family history of Keratoconus, and occupation), history of contact lens use, history of consanguineous marriages, presenting best corrected visual acuity, refractive error, clinical signs based on slit lamp biomicroscopy and best corrected visual acuity after refractive correction, were noted.Results: Of the 96 patients, 135 eyes of 72 (75%) patients were included in the study. Mean age at the time of diagnosis was 20 ± 6.7 years (8 to 40 years). 87% of them had presented bilaterally. 69.4% of them were students. Myopic astigmatism with a mean equivalent of -1.90DS and increased cylinder of -3.09DC was more prevalent. 54.1% of patients were either in advance or severe stage of Keratoconus. Spectacles were prescribed for 82 (60.7%) eyes, contact lens for 19 (14.1%) eyes, corneal collagen crosslinking with Riboflavin was done in 28 (20.7%) eyes, deep anterior lamellar keratoplasty in 4 (3%) eyes and optical penetrating keratoplasty in 2 (1.5%) eyes. There was significant improvement in BCVA from presentation in all patients.Conclusion: Age of presentation was distributed equally between 8 to 40 years of age. Majority of the patients presented bilaterally with advance to severe form of Keratoconus, which was different from published studies, where patients had presented at mild to moderate stage.
6 Sports Vision: Influence on Athlete's Performance , Patrícia Rodrigues
The ability to see and then create an appropriate motor response is central to optimal sports performance. Elite athletes face intense visuo-motor demands requiring millisecond-level decision making to convert vision into action. Some crucial skills in competition are directly linked to the visual process. It is helpful to classify the areas of assessment in order to better understand how the factors affect performance. It is analyzed a routine check in sports vision consultation, which involves the evaluation plan routine of primary and secondary skills with direct influence on sports performance. These abilities are assessment with an approach to direct correlation with the sporting skill that interferes; the way it should be evaluated and the instruments available on the market. Sport vision training aproaches provide another opportunity for the athlete to enhance vision and visual performance factors that are importante for their sport. In most sports, vision is critical element for sucessful performance and an eyecare professional should be proficient in assessing and training athletes' high-performance vision skills
7 Case of Childhood Bilateral Cataract Complicating a Polymorphous Light Eruption , CEA Filali*, F Chraibi, A Bennis, M Abdellaoui and IA Benatiya
Purpose: To detail the clinical picture and the diagnostic procedure, and to update the therapeutic management.Setting: Ophthalmology Department, Hospital Hassan II, fez.Observation: An 11-year-old boy, a young farmer, without notion of consanguinity or similar familiar cases, visited us with one year history of progressive decline in visual acuity and photophobia. Visual acuity was 6/10 in both eyes. Slit lamp biomicroscopy examination found a very embarrassed child by the light, a conjunctival thickening interesting palpebral fissure and subscapular cataract, no ocular hypertension and a normal fundus examination in both eyes. General examination revealed erythematous and papular lesions on the face, the forearms and the dorsal hands, which are itchy, evolving by relapses and remissions, and exacerbated by solar exposure.A skin biopsy was performed and histopathology disclosed a psoriasiform and spongiotic dermatosis with focal lichenoid reaction in favor of polymorphous light eruption. There were no abnormal laboratory findings, including antinuclear antibody and porphyria profiles. Thus, we diagnosed the patient with PLE complicated by bilateral cataract provoked by overlap solar exposure. Conclusion: Our case, considered as first reported in the literature, encourages good ocular protection against UV at a young age, due to possible complications
8 Outcome of India Ink Corneal Tattooing in Disfigured Corneal Scars , Pallavi Joshi, Sanjana P and Girish Budhrani
Aims: To study the outcome and safety of India ink corneal tattooing for disfigured corneal scars. Settings and Design: This was a single-centre prospective interventional case series of patients who developed corneal scars with nil visual potential and underwent corneal tattooing from June 2017-September 2018 with a follow-up period of at least 6 months. Materials and Methods: 15 consecutive cases were enrolled for the study. All patients desired a cosmetic treatment for their corneal scars in blind eye. Complete ophthalmic examination including B scan and photographs of the patients' eyes were obtained. Chemical corneal tattooing was performed using Indian Ink Powder. Patients underwent either inlay, on lay or mixed tattooing and were followed up at the first, third and fifth post-operative day, at 3rd month, 6th month and 1st year post-operatively.Conclusion: Chemical corneal tattooing is a simple, safe and an efficient technique yielding acceptable cosmetic results. It does not require expensive materials and offers a viable option in comparison to more extensive and invasive reconstructive ocular surgery. Cosmetic contact lenses being unsuitable for majority of cases owing to poor tolerance due to dust exposure and cost effectiveness tattooing of corneal opacities still has a role in cosmetic improvement in cases with unsightly corneal scars. Chemical corneal tattoo by using Indian ink as an alternative proves to give almost equivalent stable, satisfactory cosmetic result with high patient satisfaction in all cases and an improved quality of life.Statistical Analysis Used: Descriptive statistics will be calculated initially. For continuous variables, the mean, standard deviation statistics will be calculated and proportion statistics for categorical data. Results: Among the 15 cases, 7 (46%) patients underwent intralamellar tattooing, 3(20%) patients had onlay tattoo and 5 (33%) patients underwent onlay with inlay tattoo. Patients who underwent onlay tattoo noted fading of tattoo at the end of 3 months. One year postoperatively, 12 cases (80%) especially the inlay tattoo cases were more satisfied compared to onlay tattoo. All patients were asymptomatic with no evidence of any major ocular complications at the end of one year.
9 Ocular Morbidity, Clinical Profile and Visual Loss in Vitamin-D Deficiency; A Systemic Correlation , Meera Mohanakumar, Radha Annamalai, Shriraam Mahadevan and M Muthayya
Purpose: To determine the spectrum of ocular manifestations of vitamin-D deficiency/insufficiency, its effects on vision and the levels at which they occur.Materials and Methods: A prospective study done in concurrence with the department of endocrinology over a period of 1 year on 150 patients who had been referred to the ophthalmology clinic for screening and treatment of ocular complaints. Conclusion: Vitamin-D levels and genetic variations influence the development of a wide range of ocular pathologies, such as myopia, age-related macular degeneration, diabetic retinopathy, glaucoma and uveitis with its anti-angiogenic, anti-inflammatory and anti-fibrotic properties. Many tissues in the eye activate and respond to vitamin-D, suggesting that vitamin-D is a biologically relevant entity to study throughout the eye.Results: Dry eye disease(DED) was found in 102 patients (78%), followed by glaucoma in 33 (27%) patients, diabetic retinopathy in 30 (22%), myopia as the common refractive error in 25 patients (16.7%), hypertensive retinopathy in 13 out of 150 (8.7%) and age related macular degeneration(ARMD) in 6 patients (4%). Among the various ocular features, keratoconjunctivitis sicca was the most common manifestation across all age groups with vitamin-D deficiency; followed by glaucoma. In those with dry eye, decreased TBUT occurred in 30 patients and decreased Schirmer’s in 72 patients. This was found to be statistically significant with a p-value of 0.381. Among those with glaucoma, 4 (2.7%) were disc suspects, 2 (1.3%) had primary angle closure and 13 (8.3%) patients had primary open angle glaucoma and 11 had ocular hypertension. The incidence of glaucoma was higher in women with deficiency and this was found to be statistically significant with p = 0.03. Myopia in 16.7% and diabetic retinopathy in 22% were other features. Visual loss and visual field defects occurred predominantly in patients with glaucoma due to optic nerve head changes
10 The Etiology, Therapy Outcomes and Clinical Predictors among Patients Attending Low Vision Clinics at a tertiary Ophthalmic Referral Center in Tanzania , Chabane P Amisse, J Hoffman and William Makupa
Purpose: To determine the etiology, low vision therapy outcomes and predictors for good clinical outcomes among patients attending low vision therapy at Kilimanjaro Christian Medical Centre.Methodology: We report a cross-sectional, hospital-based study conducted between September 2018 and June 2019 at Kilimanjaro Christian Medical Centre in northern Tanzania. All patients who attended low vision clinic from 2015 to 2018 were reviewed. Excluded were those who had best corrected visual acuity equal to or better than 6/18, patients younger than 5 years and those with no documentation of diagnosis age and/or sex. Wilcoxon signed rank test was used to assess the visual acuity improvement and logistic regression to find the predictors for good visual outcome.Conclusion: In this study low vision therapy often resulted in good visual outcome. Despite this, visual outcome was dependent on the presenting best corrected visual acuity, meaning those most in need tend not respond. Most causes of permanent visual impairment in our setting are preventable or curable if detected early. This is another reminder that prevention is better than cure.Results: 408 patients were included in this study, of which 208/408 (51%) were adults. The 3 leading causes of permanent visual impairment in adults were diabetic retinopathy, 63/208 (30.3%); glaucoma, 21/208 (10.1%); and corneal scarring, 16/208 (7.7%). In children they were oculocutaneous albinism, 80/200 (40%); amblyopia, 20/200 (10%); and glaucoma, 15/200 (7.5%). Good low vision therapy outcome was noted in 151/175 (86.3%) of patients who had assessment for distance therapy and 113/157 (72%) in those assessed for near low vision therapy. The presenting best corrected visual acuity (distance or near) and the age of the patients were found to be significant predictors for good visual outcome (p < 0.001, for both).
11 A Good View of Brain through the Optic Nerve Window , Amir Norouzpour
Optic nerve is developmentally derived from an outpouching of diencephalon leaving the cranial cavity through the optic canal. The most anterior portion of the optic nerve called the optic disc is directly visible through the eye. With modern techniques, the in-tegrity of the optic nerve fibers can be visualized, and the structure and function of the nerve fiber layer can be precisely quantified.
12 A Clinical Profile of Corneal Ulcer in a Rural Tertiary Care Hospital , Avinash Poka, Mohan Das T and Narayan M.
Introduction:Cornea is responsible for three quarters of dioptric power of the eye and hence any injury to it can cause considerable visual disturbances. Avascularity, while absolutely essential for optical purposes is boon to multiplying organisms. In India there are about 18.7 million blind people. The incidence of corneal blindness is 15.4%, the corneal ulcer contributing (9.34%), corneal dys-trophy (0.49%), keratomalacia (1.68%), corneal opacity (3.67%) and others like keratoconus (0.09%) of this. Corneal blindness is a major problem in India, which adds a substantial burden to the community in general and health care resources all over the world. Further, individuals with corneal blindness are usually of a younger age group compared with those suffering from cataract. Hence, in terms blind years the impact of corneal blindness is greater. Objectives:1. To study the clinical features, etiology and microbiological profile of suppurative keratitis. 2. To study the course, final visual and therapeutic outcome of the cases.3. To study the various factors affecting the outcomes and their relationship with the micro biological profile and clinical appear-ance.4. To identify the signs and symptoms (which carry a poorer prognosis or may indicate a fulminant course). Materials and Methods: A prospective observational study was conducted at Department of Ophthalmic, PES Institute of Medical Sciences and Research, Kuppam study period between Jan 2018 - 2019. A total 80 subjects who diagnosed has corneal ulcer at-tending in department of ophthalmology, PESIMSR. The following inclusion and exclusion criteria was used to conduct the research programme inclusion criteria: All cases of suspected Microbial keratitis visiting cornea clinic between January 2018 to June 2019. Exclusion criteria: All cases of clinically suspected non-bacterial and non-fungal keratitis, known cases of degeneration ulcer like Moorens ulcer and Terriens. Patients below 18 years of age and patients unable to give valid consent and one eyed patients.Results:Total 85 cases was considered for the study group. Out of which male comprises 52 (61.18%) and female was 33 (38.82%) with sex ratio 1:2. The significance was tested based on the logistic regression analysis. Irrespective of gender it was found that incidence and exposure of culture organisms was statistically significant (p < 0.01). The laterality was Correlated between Culture organisms, the analysis was done multivariate logistic regression method. As per the resulted findings, the most occurrences of the organisms was Fusarium 23 (27.06%) (p < 0.01) followed by Bacillus species 14 (16.47%) (p < 0.01), Aspergillums fumigates 12 (14.12%) (p < 0.01), Strep. epidermidis 13 (15.29%) (p < 0.01), Staph aureus 11 (12.94%) (p < 0.01), Aspergillums flavus 8 (9.41%) (p < 0.01) and fewer number of organisms are showed to be Strep. pneumococcus 4 (4.71%) (p < 0.01). The occurrence of the organisms when compared with laterality and other associated factors is found to be statistically significant. Conclusion: The definitive diagnosis of ulcers caused by multiple organisms can only be arrived at by microbiological evaluation. Accurate diagnostic tests not only play a key role in patient management but also reduce the risk of the patient developing long-term complications.
13 Computer Vision Syndrome: Is it being Diagnosed and Managed Properly? , Raju Kaiti1, Purushottam Shah, Birkha Bogati, Ranjila Shyangbo, Manish Dahal and Bishal Hamal.
Computer and mobile computing devices such as laptops, tablets, or cell phones are being used by increasingly large number of people today. This has led to variety of ocular symptoms which includes eye strain, tired eyes, irritation, redness, blurred vision, and diplopia, collectively referred to as Computer Vision Syndrome (CVS). CVS may have a significant impact not only on visual comfort but also occupational productivity since between 64% and 90% of computers users experience visual symptoms which may include eye strain, headaches, ocular discomfort, dry eye, diplopia and blurred vision either at near or when looking into the distance after prolonged computer use. So, CVS acts like slow poison for ocular and visual comfort, if not taken into consideration timely. CVS has a multifactorial causation. Several factors have been linked to symptoms. But how often has it been diagnosed and managed properly? The answer is “not satisfactory”. Most of CVS cases have been dispensed merely with eye drops and no other orthoptic interventions and ergonomic awareness are suggested, especially in developing countries like Nepal. A specially designed ocular examination for computer users and associated counseling about the current good practice in computer use would go a long way in preventing loss of productivity and morbidity from the condition.
14 Bulging of Posterior Capsule Associated with Choroidal Effusion during Phacoemulsification , Saraswati J, Umesh Y, Priyanka Sudhakar and Pradeep Bastola.
We report an interesting and a relatively rare case of intraoperative choroidal effusion, during a routine phacoemulsification in a seemingly normal senile cataract, with a bulging of posterior capsule and shallowing of anterior chamber because of choroidal effu-sion which is a very rare intraoperative event in an elective case of phacoemulsification.
15 Serial OCT Imaging of Retina in HELLP Syndrome , Tony Y Chen and Neelakshi Bhagat.
Exudative retinal detachment (ERD) is a rare ophthalmic complication of eclampsia and HELLP syndrome. We report a case of acute painless severe vision loss in a multigravida pregnant woman with HELLP syndrome caused by bilateral ERDs. The use of systemic corticosteroids, and meticulous blood pressure management, resulted in rapid resolution of subretinal fluid and visual re-covery. Disruptions in ellipsoid zone and retinal pigmented epithelium, however, persisted for months after resolution of subretinal fluid.
16 Evaluation of Retinal Nerve Fiber Layer and Ganglion Cell-Inner Plexiform Layer Loss in Patients with Primary Open Angle Glaucoma , Mohamed M Almbsut, Amira G Abdelhameed, Dalia S El-Emam and Asaad A Ghanem.
Aim:This study aimed to compare peripapillary retinal nerve fiber layer (RNFL) and macular retinal ganglion cell-inner plexiform layer (GC-IPL) changes in patients with primary open-angle glaucoma with control subjects by Swept Source optical coherence to-mography. Methods:This was a comparative cross-sectional study included 40 eyes of 40 POAG and 40 eyes of 40 control subjects. Ophthalmic examination, measurement of intraocular pressure, Visual field evaluation by using Humphrey (2003 Carl Zeiss Meditec, Germany) were done. All subjects were scanned using swept source Optical Coherence Tomography (Triton, Topcon, Tokyo, Japan) imaging to measure Macular GC-IPL thickness, peripapillary RNFL thickness. Results:The mean age of the patients with POAG was 58.20 ± 9.12 years; 26 eyes (65.0%) were male and 14 eyes (35.0%) were female. The mean age of control subjects was 54.10 ± 9.11 years. The mean visual field MD was -11.30 ± 6.88 db, SE was -3.43 ± 1.08 D, CMT was 164.3 ± 16.62 Um and IOP was 15.25 ± 1.33 mmHg in patients with POAG, whereas mean visual field MD was -0.97 ± 0.39 db, SE was -3.23 ± 1.04 D, CMT was 170.6 ± 9.21 Um and IOP was 13.20 ± 1.18 mmHg in control subject. A statistically significant dif-ference of IOP, visual field MD was detected between the study groups with p value (p < 0.001). the Mean Macular GC-IPL thickness and peripapillary RNFL thickness were significantly decrease in POAG patients when compared with controls (p < 0.001). Conclusion:Retinal nerve fiber layer and ganglion cell-inner plexiform Layer by Swept-source OCT showed statistically significant decrease in POAG patients.
17 Corneal Lenticule Implantation in Keratoconus Disease with Relex Smile Surgery , Faruk Semiz, Anita Syla Lokaj, Njomëza Hima and Olcay Semiz.
Purpose:The aim of our study is to investigate the feasibility and effect of fresh lenticule implantation as allogenic graft that will be taken from myopic patients to implant in patients with keratoconus disease using VisuMax Femtosecond laser- Smile module surgery with primary objective to increase central corneal thickness and secondary to improve visual acuity and reduces K-values. Methods:All the patients were clinically diagnosed with progressive keratoconus. Twenty patients underwent SMILE surgery (first group), and 20 patients underwent lenticule implantation (lenticule group). Visual acuity, corneal topography, anterior segment opti-cal coherence tomography, were analyzed. Results:Central corneal thickness were improved at the same day of surgery and vision started to improved at first week postop-eratively in the lenticule implant group. Corneal topography showed a statistically significant decrease in the anterior K1 and K2. All the grafts from both groups were clearly visible by anterior segment optical coherence tomography observation. The central corneal thickness was stable during the 6-month study period. No complications were observed during short term follow-up. Conclusion:In conclusion, the present study may suggest that this procedure using fresh lenticule with stromal stem cells and live keratocytes is safely, reliably, and effectively increase corneal thickness and improves visual acuity with no adverse effects, which may provide new avenues in the treatment of corneal ectasia.
18 A Rare Case Report of the Posterior and Bilateral Persistent Hyperplastic Primary Vitreous (PHPV) , Japhet Pobanou Thera, Tiama JM, Konipo A and Dakouo P.
Purpose:The aim of our study was to report a rare case of persistent hyperplastic primary vitreous. Case Report:A 4-year-old girl was brought by her parents for impaired visual acuity. The examination of the lens found a tiny opaci-fication. Fundoscopy revealed a membranous proliferation extending from the papilla to the posterior surface of the lens. Discussion:The persistent primary vitreous is a congenital abnormality. It is due to a failure of regression of the embryonic vitreous to which is added the persistence of the hyoid artery. It occurs around the 6th week of embryo development. Conclusion:Persistent hyperplastic primary vitreous (PHPV) is a rare congenital anomaly. It has many forms. The Posterior form and the isolated bilateral one is rare.
19 Reopening Our Practice and the Woes of the Pandemic , Sana Nadeem
For most of us, the Severe acute respiratory syndrome corona-virus 2 (SARS-CoV-2) is the first and worst pandemic we have ever faced. From its beginnings in Wuhan, China in December 2019; it has exploded; now affecting 213 countries and 10.27 million people worldwide. Claiming 505,071 lives so far; this deadly virus is raging still [1]. A large number of health workers have fallen prey to this virus, which plummeted most of the world into lockdown. As we ophthalmologists were forced to limit our practices to ur-gent cases only; questions now arise on how to keep ourselves’ and our patients’ safe; as the lockdown eases
20 The Role of Jankovic Spasm Grading, Orbicularis Oculi Muscle Function and Functional Improvement Scale Pre-and Post-Treatment in Dosing Botulinum Toxin A in Treatment of Essential Blepharospasm, Meige’s Syndrome and Hemifacial Spasm , Bastola P and Koirala S
Abstract Background:Botulinum Toxin A (BTX A) is a proven medication used in neurological disorders like Meige’s syndrome (MS), essen-tial blepharospasm (ES) and hemifacial spasm (HS). Jankovic spasm grading is a time trusted grading system to detect the severity of these movement disorders pre-treatment. Orbicularis oculi muscle weakness and functional improvement ratings post treatment are trusted guidelines to judge the efficacy of BTX A. Aim/Objective: The study aimed to find out the correct dosing of BTX A in treating cases of MS, ES and HS using Jankovic Spasm grading pre-treatment and orbicularis oculi muscle weakness and functional impairment improvement post treatment. Methods: This was a hospital based, interventional, prospective study. All diagnosed consecutive patients of HS, ES and MS attend-ing the neuro-Ophthalmologic/oculoplastic clinic, general outpatient department of Ophthalmology and or referred diagnosed cases were enrolled for the study, an informed consent was taken from all the patients before the treatment for medico-legal issues. The pre-treatment dosing was done using Jankovic spasm grading, post treatment assessment was done using orbicularis oculi muscle assessment and functional improvement. The study subjects were followed up to 9 months or till spasms reappeared. Results:A total of 50 study subjects were enrolled in the study, 80% of them were women. The highest number of study subjects were in ES (50%) group followed by HS (40%) and MS (10%). Mean Jankovic spasm grading in all study subjects was 3.59 (± 0.38 Std. deviation). The study groups ES and MS required a higher dose of BTX A (P value: < 0.0001) when compared with HS study group. Mean orbicularis oculi muscle weakening and functional impairment improvement scale in all study subjects was 2.7 (± 0.3 Std. de-viation) and 3.8 (± 0.6) respectively. Mean duration of action till the spasms reappeared in the study subjects was 5.1 months (± 1.7 Std. deviation). HS and ES study groups had better treatment when compared to MS. Conclusions:Jankovic spasm grading pre-treatment and orbicularis oculi muscle weakness grading and functional improvement score post treatment plays a very effective role to titrate the correct dose of BTX A in patients of HS, ES and MS.
21 Assessing Awareness and Attitudes of the Arab Diabetic Population in Israel towards their Illness Via Ophthalmic Follow Ups and Questioners , Yael Pikkel Igal, Igal Vadim, Yoav Y Pikkel and Dvora Pikkel
Abstract Background: Diabetes care requires close monitoring and ongoing treatment to minimize related complications. The Arab population in Israel is characterized by high prevalence of diabetes and poor disease control compared to other subpopulations in the region. This study assessed awareness to the disease and self-reported care among Arab persons with diabetes living in northern Israel via examining rates and sequences of ophthalmic examination follow ups and verified questioners. Method: The study was carried out at the outpatient ophthalmic clinics in three Arab towns in Israel. A bilingual (Arabic and Hebrew speaking) physician administered an oral survey that accessed information regarding the awareness of patients towards their disease and their self-care. The survey comprised 12 questions relating to definitions, causes, compliance and attitudes towards diabetes. The patients' responses were compared to the data in their medical files. Results: Participants were 44 men and 56 women. Only 43% acknowledged having diabetes. Twenty (47%) individuals who acknowledged having the disease reported taking their medications regularly, 23 (51%) reported exercising regularly, and 38 (88%) reported visiting an ophthalmologist within the previous year; compared to 0 (0%), 7 (12%) and 38 (67%) respectively of those who did not acknowledge having the disease. Conclusion: This study showed a very low level of awareness of diabetes among patients diagnosed with the disease, as manifested by complete denial of the disease despite recommendations for treatment and large gaps in understanding. Though ophthalmic visits were relatively better in patients with acceptance and denial there are still cultural and socioeconomic barriers that hinder recognition and care of diabetes among Arab Israelis should be addressed.
22 Managing Corneal Epithelial Defects Using High Molecular Weight Fluorescein to Prevent Contact Lens Staining and Removal of Bandage Contact Lenses , Muhammad Hamza, Chrishan Gunasekera, Samar Nahas, Z CX Lin, Hatch Mukherjee and Richard Allen
Abstract: Method: A small group of patients with epithelial defects requiring bandage contact lenses were identified at Colchester Hospital University Hospital. Both Purevision lenses and Biofinity contact lenses were utilized. The lead researcher took anterior segment photography initially devoid of fluorescein. After Fluorosoft was introduced, the process was repeated where anterior section photograph was acquired after 30 seconds to guarantee Fluorosoft was fitted under the lens. Subsequently, removal of the bandage contact lens followed. Later, pictures of the bandage contact lens were taken to evaluate the staining. A second photography was obtained on the anterior segment photograph in order to compare the epithelial defect visibility with normal fluorescein relative to Fluorosoft. Conclusion: • Main aim for this exercise is find a way of not replacing BCL on each examination without compromising the assessment of corneal epithelial defects hence reducing the chance of infection. • The research demonstrates that the fluorosoft (high molecular weight fluorescein) can successfully detect epithelial deficiencies in patients having a series of bandage contact lenses devoid of lens’ staining.
23 Serpentine Appearance of Giant Retinal Tear , Lagan Paul, Neha Chowdhary and Ranobir Ghosh
Giant retinal tears (GRTs) are described as full-thickness cir-cumferential retinal tears involving more than 3 clock hours (90 degrees) of the peripheral retina . GRTs are caused by vitreous traction on the peripheral retina in the area of the vitreous base as there is condensation of the peripheral vitreous along with liq-uefaction of the central vitreous. Due to subsequent transvitreal contraction of the cortical gel, the tear occurs along the vitreous base in a zipper fashion.The sonographic appearance of the GRT has been described in literature as a double linear echo that is dis-continuous with the contour of the globe . We describe the ser-pentine appearance of the GRT on ultrasound B scan
24 Managing Postoperative Astigmatism in Cataract Surgery: A Short Review , Mohammed Abdulkarem and Mustafa Ali Shata
Abstract Cataract surgery is no more a visual rehabilitation surgery. Today along with cataract removal, astigmatism correction has become a routine procedure. Patients want a spectacle free life at any stage of life. 10 years before it was still impressive to have a residual of +2.0 D astigmatism following cataract surgery. But in last 10 years, a lot of technological advancement has happened. The residual astigmatism following cataract surgery has come down from 1.5D to 0.75D, even 0.5D when a premium IOL is implanted. Here we are going to discuss in short the journey of astigmatism correction from choosing the incision in steep axis to Toric IOL implantation and so on.
25 Micro-pulse Diode Laser Transcleral Cyclophotocoagulation- A Rescue in Therapeutic Exhaustion , Meena Menon, Shreeshruthi N, Anand Balasubramaniam and Harshavardhan VK
Abstract Essential iris atrophy (EIA) is one of the most common irido-corneal endothelial syndromes, predominantly characterised by pro-gressive iris stromal atrophy leading to iris hole formation and secondary glaucoma. Predominantly unilateral in affection, glaucoma is refractory to both medical and surgical management. We hereby report a rare case of association of EIA with primary open angle glaucoma (POAG). Glaucoma progressed with the maximum medical treatment and surgical intervention. Micro-pulse diode laser transcleral cyclophotocoagulation (MP-TSCPC) proves effective in control of intra-ocular pressure (IOP) in refractory glaucomas, especially in eyes with good central vision.
26 Comparative Study of Visual Outcomes Following Vitrectomy for Nucleus Drop Caused by Various Aetiologies , Mehul Shah, Shreya Shah, Ruhi Gunay and Raunaq Khanna
Abstract Purpose: Nucleus drop is a rare and serious complication. We investigated visual outcomes following corrective surgery and compared outcomes between surgeries performed in various aetiologies. Method: A retrospective cohort study was performed after obtaining the approval of the ethical committee. The data of patients who underwent vitrectomy for nucleus drop were collected from electronic medical records. Patients were grouped based on the following aetiologies: traumatic, iatrogenic, spontaneous, and congenital. After pars plana vitrectomy and nucleus removal, comorbidities were managed either medically or surgically. All data were collected according to a pretested format and exported to SPSS 22. Results: Our cohort consisted of 169 eyes of 169 patients. The mean age of patients was 55.36 ± 15.7 years. Of 169 patients, 107 (63.3%) were men and 62 (33.7%) were women. Of 169 patients, 44 (26%) were classified as having traumatic nucleus drop and 125 (74%) developed spontaneous nucleus drop without trauma following cataract surgeries (Table 2). In the iatrogenic group, 33 (38.56%) patients developed nucleus drop during phacoemulsification and 59 (62.9%) following MSICS. Conclusion: The visual outcome following corrective vitrectomy for nucleus drop may be satisfactory if managed well; no significant difference in the outcome was noted based on the aetiology.

28 A Case Series of Conjunctival Rhinosporidiosis: Extremes of Presentation , Shobita Nair, Anitha Venugopal, Vinit J Shah and Meenakshi Ravindran
Abstract Rhinosporidiosis is a rare infection caused by Rhinosporidium seeberi, an organism classified into class, Mesomycetozoea. It com-monly affects mucus membranes. The diagnosis of rhinosporidiosis is based on its clinical appearance, microscopic features and the treatment is surgical excision. This condition is endemic in the temperate regions of the Indian subcontinent. Although a rare clinical entity, the possibility of rhinosporidiosis must be considered when evaluating any polypoidal conjunctival mass in patients belonging to any socioeconomic strata. Here we present 3 patients of different age groups and socioeconomic status with varied presentations suggestive of Conjunctival rhinosporidiosis, their evaluation, management, and outcomes

30 A New Approach to Microsurgical Medical Education: Mobile Phone Repairs , José Henrique Fazzi, Marina Schor and Paulo Schor
Background: Technology has been increasingly used as a teaching tool in medical education, and simulation training is at the fore-front of that shift in teaching methods. This project proposes an innovative tool for training students in microsurgery. Through fixing their cell phones under the guidance of a supervisor, students got a chance to improve their technique in microscope use. Furthermore, the procedure allowed for students to discuss insecurities surrounding the performance of microsurgery. Materials and Methods: Eight students from the Federal University of São Paulo were involved in the project and were selected through a phone screening process. Those students brought in their own faulty cell phones which were the main materials used. Other materials included pieces that needed replacing in the phones and the tools needed to open, close and handle the apparatus generally. Results: 87.5% of the students achieved the expected result with a successful procedure and 25% of students had technical problems during the procedure. 75% of students, however, had no major technical problems during the procedure. Two of the eight students who participated in this project had trouble with the cell phones one month after the procedure. The remaining had fully functional devices. Conclusion: The majority of students successfully completed the cell phone repairs. Overall, there was a high level of acceptance of the project by students as a successful learning tool which increased both their abilities and self-confidence. Students overall left satisfied with the activity and said they would recommend it to others.

32 Lid Hygiene Versus Lid Hygiene Plus Microblepharoexfoliation for the Treatment of Demodex folliculorum Blepharitis , Michael B. Choi and Rebecca Stein
Purpose:To compare lid hygiene versus lid hygiene and microblepharoexfoliation (MBE) (BlephEx®) in the treatment of Demodex folliculorum blepharitis.Methods:This study was an Institutional Review Board approvedrandomized prospective single masked trial of 50 patients with microscopically proven Demodex blepharitis. All subjects received lid hygiene two times a day and half were randomized to in-office MBE treatment. All subjects at baseline and one month were evaluated for the total number of Demodex on 4 eyelashes, Ocular Surface Disease Index (OSDI), tear osmolarity, MMP-9, Schirmer 1, Non-invasive tear break-up time (NIBUT), lipid layer thickness, meibography, lissamine green staining, and eyelid margin exam. Results:The total number of Demodex decreased by 3.88 from baseline to month 1 for the lid hygiene plus MBE group vs. 0.4 for the lid hygiene alone group (p < 0.001). NIBUT increased 1.1 seconds from baseline to month 1 for the lid hygiene plus MBE group vs. 2.8 seconds for the lid hygiene alone group (p = 0.52). All other measurements were similarly not statistically significantly different (lipid layer thickness, OSDI, Osmolarity, MMP-9, Schirmer 1, meibography, lissamine green staining, and eyelid margin exam). Conclusion:Both lid hygiene plus MBE and lid hygiene alone decreased the amount of Demodex with the group receiving MBE showing a greater decrease that was statistically significant (p < 0.001). MBE may have a positive role in the treatment of Demodexblepharitis
33 Deficit Convergence and Headache: The Invisible Facts , Gaurav Dubey, Mahesh Chandra, Ragni Kumari, Richa Jangra and Aysworya Mohapatra Suneel Kumar Dixit
The inadequate convergence is a state where your eyes will not cooperate if you look at objects in the vicinity. This disorder allows one eye to face out with the other eye, instead of inward, causing a double or blurred vision.Insufficiency in fusion is normally diagnosed in children and teenagers in school age. It may cause reading problems, about which parents or teachers can believe the child is experiencing learning difficulties rather than an eye disease. Persons of all ages can be treated with convergence insufficiency after a stroke or traumatic brain injury

De-spite early initiation of both topical and systemic antibiotic therapy the baby had a deteriorating course and the eye was eviscerated.
35 Optimum Utilization of Electric Bulbs , B Shukla
Centuries back all work was done during daytime and night was utilized mainly for rest. In modern times with the development of electric gadgets little difference is left between day and night. Nevertheless, in developing countries and more so in rural areas still electric filament bulbs are the commonest source of illumination. Even in daytime electric bulbs are needed for indoor work. However, the use of these bulbs has been mainly empirical by common sense as knowledge about illumination is rather primitive even in cities and in educated persons also.Continued use of improper illumination is a very common cause of eye strain which may lead to great discomfort and even organic disease. Students who form a large bulk of population suffer the most as they have to read for long hours. In the present work an effort has been made to measure the illumination emitted by different type of bulbs by a luxmeter at different distances. Theoretical requirement of illumination is available from books but hardly anyone knows how to get that illumination by electric bulbs. Even an approximate required illumination for different types of work has been worked out. If this guideline is followed many persons suffering from eye strain can be relieved without any medicine. The efficiency of work will also increase.
36 Needs and Challenges of Correction of Refractive Error among School - Aged Children , Nahid Ferdausi
Visual impairment from uncorrected refractive-errors can have immediate and long-term consequences in school-aged children, such as lost educational opportunities, lost an economic gain for individuals, families, and societies, and impaired quality of life. Un-corrected refractive-error is recognized as the principal cause of visual impairment in school-aged children as failure to the treatment of refractive-error in children may lead to Amblyopia which turns into the blindness of the children.
37 Challenges Face during Fitting of RGP Contact Lenses in Keratoconus , Shivam Bajoria
Introduction: RGP contact lenses is of paramount importance in Keratoconus patient management to rehabilitate vision and improve patients quality of life.There’s always been on focus to find alternative to Contact lenses options which is already been proposed. Like if patient show contact lens intolerance or disease progresses, basically the surgical procedures along with the non optical options can be applied, as looking on to which option the patient is more convenient according to his requirement.Also there's can be an option of Scleral Contact Lenses which can even be the first choice if the RGP intolerance occurs or there can be the option of Kerasoft lenses if the comfort is the main priority of the patient.
38 Evaluation of the Efficacy of Single Dose of Intravitreal Bevacizumab in the Management of Macular Edema due to Retinal Vein Occlusions , Vinit Shah, Panneer Selvam V, Sindhanai VP, Shobita Nair, Amal Gupta, and Radha Jayaraman
Aim: Evaluation of the efficacy of single-dose intravitreal Bevacizumab in the management of macular edema due to retinal vein oc-clusions. Objectives: 1. To evaluate the efficacy of single-dose intravitreal bevacizumab in the management of macular edema due to retinal vein occlu-sions in terms of reduction in central macular thickness. 2. To evaluate the efficacy single dose of intravitreal bevacizumab in the management of macular edema due to retinal vein occlu-sions in terms of improvement in visual acuity. 3. To evaluate the change in the Intraocular pressure in the eyes receiving intravitreal Bevacizumab. Methods: This study was an Institutional Review Board approved prospective interventional study done in a Retina clinic at a ter-tiary eye hospital, where 45 patients were enrolled. All patients clinically diagnosed to have retinal vein occlusions with macular edema with all risk factors were enrolled for the study. After informed consent, all participants were subjected to the following examinations, visual acuity was recorded on Snellen’s vision chart, followed by anterior segment evaluation, intraocular pressure, go-nioscopy, slit-lamp biomicroscopy with 90D lens and fundus finding were confirmed by indirect ophthalmoscopy. Optical coherence tomography was done in every patient. The diagnosis of macular edema was established by clinical examination and optical coher-ence tomography was done to quantify central macular thickness (CMT) at baseline, 4 weeks and 8 weeks after a single injection of 1.25 mg (0.05 ml) intravitreal Bevacizumab. Results: The mean central macular thickness (CMT) at presentation was 482.88 μm ± 173.6 μm (SD). The mean CMT decreased from baseline to 314.3μm ± 129.9 μm at one month. The mean CMT decreased to 237.1 μm ± 97.08 μm at the end of 2 months which was statistically significant (p < 0.05). The logarithm of minimal angle of resolution (logMAR) vision at presentation 1.043 ± 0.443 improved to 0.690 ± 0.424 and 0.529 ± 0.440 at 1 month and 2 months respectively (p < 0.05). There was no statistically insignificant change in IOP after a single injection of Bevacizumab. Conclusion: Intravitreal Bevacizumab even in a single dose is effective in the treatment of all types of retinal vein occlusions. There was a statistically significant improvement in visual acuity, the decrease in the central macular thickness was also statistically signifi-cant and effects were maintained throughout the follow-up period without any changes in IOP
39 How Often Should Healthy Optic Nerves be Scanned for the Development of Glaucomatous Optic Neuropathy? , Paul Varner
Background: No data exist for the time period required for the conversion of healthy optic nerves to glaucomatous optic neuropathy (GON). It is not possible to predict which patients will develop glaucoma. Periodic screening of ONHs via nerve fiber layer (NFL) scans might allow for the early detection of GON. Method: Retrospective chart review of patients who developed definitive unilateral (n = 18) or bilateral (n = 13) glaucoma to de-termine time course for conversion to/discovery of GON, as corroborated by optic nerve head (ONH) evaluation, NFL scans, and automated visual field (VF) perimetry.Results: Median time of conversion for this cohort was 7 years for unilateral and 8 years for bilateral GON. Conclusion: Screening ONHs/NFL at five-year intervals may be adequate for the detection of new cases of GON in its early stages.
40 Outcome of External Dacryocystorhinostomy with Excision of Both the Anterior Lacrimal Sac and Nasal Mucosal Flaps and Preservation of the Posterior Flaps , Abdullah S Al-Mujaini1*, Maryam S Al-Issai2 and Buthaina I Sabt
Purpose: An external dacryocystorhinostomy (Ex-DCR) is a surgical procedure wherein a fistula is created between the lacrimal sac and nasal mucosa. Although the conventional approach to an Ex-DCR procedure is time-consuming and may result in complications, it is considered the gold-standard technique for the management of nasolacrimal duct obstruction (NLDO). This study aimed to evaluate the outcomes of a modified Ex-DCR approach with intubation and in which both the anterior lacrimal sac and nasal mucosal flaps were excised while the posterior flap was left hanging free. Methods: A retrospective chart review study, included all consecutive adult patients with primary NLDO who underwent modified Ex-DCR procedures. Data were collected from electronic patient records, including oculoplastic and orbital surgical notes. All pa-tients underwent a minimum of 12 months of follow-up. Success was defined according to lacrimal patency and symptomatic relief. Results: A total of 45 patients underwent modified Ex-DCR procedures with intubation and excision of both the anterior lacrimal sac and nasal mucosal flaps. During the 12-month follow-up period, 43 (95.6%) demonstrated a patent lacrimal drainage system and were symptom-free. Two patients (4.4%) developed secondary obstruction with persistent epiphora. Conclusion: The excision of both the anterior lacrimal sac and nasal mucosal flaps during a modified Ex-DCR procedure resulted in a high success rate comparable to that reported in the international literature with standard techniques. In addition, this procedure might shorten the surgical time required. However, further studies are required to determine if such modifications hold a statistical advantage over conventional techniques.
41 Ocular Morbidities among the Elderly Attending Outreach Eye Care Clinics in Gandaki Zone, Nepal , Pawan Baral, Indraman Maharjan, Nabin Baral and Bhoja Raj Gautam
Purpose: To determine the causes of visual impairment in patients attending outreach services in Gandaki, Nepal. Methods: This was a prospective cross sectional study conducted within two districts of Gandaki Zone Nepal. The patients forty years and above and attending the screening outreaches conducted by Himalaya Eye Hospital (HEH) were taken for the study. The pa-tients attending the screening outreach underwent a thorough eye examination by an Ophthalmologist and an ophthalmic assistant. For the purpose of the study we only considered the distance and near visual acuity and the diagnoses. Distance visual impairment (DVI) was categorized as the presenting visual acuity of worse than 6/18 to 3/60 in the better eye. Blindness was categorized as the visual acuity of worse than 3/60 in the better eye. For all subjects the near visual impairment (NVI) was categorized as the present-ing near vision of worse than N8 at patient’s preferred reading distance. The main cause of distance visual impairment or blindness was considered the main diagnosis. Results: Eight hundred sixty-two subjects within the age group forty and above were taken for the study. The mean age of the study subjects was 64.75 ± 10.65. The odds ratio of having DVI in persons aged 60 years and older compared to those aged less than 60 years was 4.79 (CI: 2.94 to 7.83; p < 0.0001). The odds ratio of having DVI among illiterates compared to those who were literates was 2.77 (CI: 1.96 to 3.92; p < 0.0001). The odds ratio of having DVI among widowed individuals compared to married or single individuals was 2.86 (CI: 1.44 to 5.63; p = 0.002). 818 (94.9%) of the study population had NVI. The proportion of subjects who had NVI differed significantly between the occupations χ2 (3, N = 861) = 14.37, p = .006. Cataract was the main cause of DVI (56.47%) followed by Age-Related Macular Degeneration (ARMD) (15.29%), refractive error (12.35%), and others (7.06%). Conclusion: These data indicate that DVI and NVI is common in elderly population in Gandaki zone. The DVI and NVI are specifically dependent on the age, education level, occupation and marital status of the elderly people. Considering these factors as the determi-nants of vision loss, more focus on eye care services need to be provided to the population within these categories.
42 Sonographic Features and its Association with Visual Outcome and Microbiological Profile in Acute Post Cataract Surgery Endophthalmitis - A Prospective Analysis , Tharini Senthamizh, Tanpreet Pal Singh, and Haripriya Aravind
Background and Aims: Cataract surgery is the commonest eye surgery performed worldwide. Endophthalmitis is a sight threaten-ing complication of cataract surgery which causes reduced vitreous clarity and media opacities and precludes visualization of the posterior segment. Ultrasonography is done in cases of suspected endophthalmitis with poor media clarity. This study aims at evalu-ating, baseline sonographic features of acute post-cataract surgery endophthalmitis and its association with initial vision, final visual outcome and microbiological profile. Materials and Methods: This prospective study conducted at Aravind Eye Hospital, Madurai, South India, included all patients who presented with clinical symptoms and signs of endophthalmitis, between January 2014 to December 2015. They underwent A-mode and B-mode ultrasonography and were managed with either ‘tap and inject’ strategy or primary vitrectomy and followed up for three months. The sonographic features like vitreous opacities, vitreous membranes, retinal detachment, choroidal detachment, posterior vitreous detachment, and retino-choroidal thickening were documented and their association with vision at presentation, microbio-logical profile and final visual acuity was studied. Results: There were 54 patients (54 eyes), their mean age was 59.9 ± 19.2 years and male : female ratio was 1:1. Of them, 33 patients (61.1%) had dense vitreous opacities, 16 patients (29.6%) had dense vitreous membrane, 3 patients (5.6%) had retinal detachment and 1 patient (1.9%) had choroidal detachment. Median retino-choroidal thickening was found to be 1.82 mm (1.67-1.96 mm). In-creased retino-choroidal thickening (P = 0.049) and dense vitreous opacities (P = 0.000) was significantly associated with poor initial presenting acuity. The occurrence of retinal detachment was significantly associated with poor final vision (P = 0.006) and infection by virulent organisms (P = 0.028). Conclusion: In conclusion, sonographic warning signs are associated with infection by virulent organisms and poor visual outcome.
43 A New CM T Flex Aphakia Foldable IOL with Trabeculectomy for a Case of Traumatic Aphakia with Secondary Glaucoma , Nivean M, Murali Ariga, Pratheeba Devi Nivean and Archana N
Here, we report a case of 37-year-old male who came with a history of traumatic aphakia in the right eye 10 years back along with uncontrolled intraocular pressure (IOP). His Uncorrected vision was hand movements in the right eye at presentation. He was managed with a new CM T-FLEX foldable aphakic scleral fixated intraocular lens with superior trabeculectomy. Fornix based conjunctival partial-thickness triangular scleral flap of 4mm were raised. Mitomycin c was placed for 1 minute. Surgical iridectomy was done using Kelly's punch. Flap closed with releasable sutures. Two partial-thickness limbal-based scleral flaps of 2.5mm*2.5mm were created 180 degree apart; sclerotomies were made using 23G needle 1.5mm away from limbus. The new CM T-flex intraocular lens was injected through the 2.8mm clear corneal incision and the specially designed T shaped lens haptics were externalised with the 23G PraNiv T flex forceps, brought out and left under the scleral flap and using the hand shake technique the second arm was grasped using the NiShi Grasping forceps and exchanged to the PraNiv T flex forceps and brought out through the other sclerotomy. The intraocular lens was stable. Anterior chamber wash was done and air bubble was injected. Fibrin glue was used to close the scleral flaps and conjunctiva. Postoperative period was uneventful. At the end of 1 month, the patient's best corrected visual acuity was 6/24 in the right eye with a good filtering bleb superiorly and a stable, well-centered CM T flex Aphakia intraocular lens.
44 Perception and Scenario of Contact Lens Use in Developing Countries like Nepal , Raju Kaiti and Ranjila Shyangbo
Contact lenses have been making a huge difference to the life of their wearers, providing a certain level of freedom that traditional glasses are unable to. Their existence has been a boon especially for those living with refractive or cosmetic ramifications, as some-times with contact lens use it is impossible to judge if a person is visually impaired or has significant cosmetic concerns. Nowadays, beside their therapeutic and refractive use, contact lenses have been sought-after cosmetic enhancement of the eye. Although the use of contact lenses has been preceding ahead of other means of refractive corrections in developed countries, their use has been stigmatized and severely misunderstood in developing countries like Nepal. Could it owe to lack of knowledge on contact lenses among the patients or are we, eye care professionals, failing them due to our ineptitude to provide proper patient education on con-tact lenses?
45 Does Hypovitaminosis A in Mothers Cause Congenital Malformation of the Eye? , Shreya Shah, Mehul Shah, Ashit Desai, Mrugesha Vaghela and Deeksha Thorat
Abstract Introduction: Congenital malformation is an important cause of childhood blindness. Hence, we attempted to study the factors responsible for it. Methods: This was a retrospective cohort study. We collected data from our hospital EMR for the period 2008 - 2019. We retrieved the total number of paediatric outdoor and children with congenitally malformed eyes. We also explored the history of night blind-ness in mothers during pregnancy, exported the data to excel sheets, and calculated the type of anomalies using descriptive analyses with SPSS 22. Results: Our cohort included 1435 children out of the total 100946 (1.42%) outdoor of paediatric ophthalmology. We found various anomalies in our analyses. We discerned that 423 (29.47%) cases had a history of night blindness to mother during pregnancy, sug-gesting vitamin A deficiency. Conclusion: Based on our clinical observation, it could be concluded that hypovitaminosis A in mother results in maldevelopment and congenital anomalies of the eye in children.Keywords: Vitamin A Deficiency; Congenital Malformation of Eye; Hypovitaminosis A in Mothers
46 Low Level Light Therapy as an Adjunct Treatment for Meibomian Gland Dysfunction , Karl Stonecipher, Casey Komm and Richard Potvin
Abstract Importance: This study highlights the adjunctive value of low-level light therapy (LLLT) in the management of meibomian gland dysfunction (MGD). Background: To evaluate the effects of LLLT treatment on clinical measures of dry eye related to MGD in patients unresponsive to previous therapies.Design:A retrospective chart review of patients treated at one site.Participants:Fifty eyes of 25 treated patients who were documented treatment failures with previous pharmaceuticals and/or devices were evaluated.Methods: LLLT treatment consisted of 3 treatments in one week, with adjunct use of a topical steroid/antibiotic combination. The post-treatment diagnostic measures had to have been made 3 to 5 weeks after the last LLLT treatment. Main Outcome Measures:Results included changes in the graded MGD score (grading scale 0 - 4), tear breakup time (TBUT), an Ocular Surface Disease Index (OSDI) questionnaire score and lissamine green (LG) staining. Results: Significant improvements in the mean OSDI score (p = 0.002), MGD grading (p < 0.001), TBUT (p < 0.001) and both nasal and temporal LG staining (p < 0.02) were observed after treatment. An MGD grade reduction of 1 or more was observed in 72% of eyes (36/50), and 2 or more in 32% of eyes (16/50). There were no ocular or facial adverse events or side effects related to the treatment. Conclusion: The application of LLLT over a short series of sessions for the treatment of MGD appeared to be beneficial in the majority of patients who had failed to improve with alternative pharmaceutical and device interventions.
47 Evaluation of the Efficacy of Subconjunctival Anti Vascular Endothelial Growth Factor Antibody Injection in the Treatment of Retinopathy of Prematurity in an Experimental Rat Model , Tuncay Topal, Yakup Aksoy and Ali Ayata
Abstract IntroductionVEGF plays an essential role in the vasoproliferative process in ROP. It is secreted from Müller cells and astrocytes in response to hypoxia caused by hypoperfusion in the retinal layers. Inhibition of VEGF bioactivation is a key target in the treatment of ROP [1]. The first attempt in ROP treatment was the ablation of VEGF-pro-ducing retinal avascular areas. For this, cryotherapy was first used Purpose: To observe the effect of subconjunctival (SC) approach for the treatment of retinopathy of prematurity (ROP) in an experi-mental rat model. Methods: We used 4 groups (G) comprising 18 new-born rats in each. G1: healthy control, G2: untreated oxygen induced retinopathy (OIR) control, G3: SC rat anti vascular endothelial growth factor antibody (antiVEGFab) injected and G4: Intravitreal (IVT) antiVEG-Fab injected. G2, G3 and G4 were exposed to oxygen fluctuations alternating between 50% and 10% every 24 hours until postnatal day (p) 14 at which time the groups were placed into room air for 4 days. At p18; OIR was observed through fluorescein angiography (FA). G3 and G4 were treated immediately 1 μg/10 μl and 50 ng/2 μl respectively. FAs repeated at p19, p25 and p30. To evaluate OIR; modified retinopathy scoring system (MRSS) was calculated according to the FA images, including retinal vascular development, vascular tuft formation, extraretinal neovascularization, vascular tortuosity and retinal haemorrhage. Blood analysis was performed on the same three days for the measurement of serum VEGF levels. Histopathological evaluation was performed with haematoxylin & eosin staining for the vascular lumen quantification on the retinal specimens of the enucleated eyes on the same days.Results: There was no significant difference between the G3 and G4 at the end of the study according to the MRSS values(p: 0,101), systemic VEGF levels (p: 0,796) and vascular lumen counts of histopathological specimens (p: 0,359). Conclusion: The therapeutic effect of SC and IVT on OIR were similar. SC anti VEGF treatment may be a safer and effective alternative to IVT injection for the treatment of ROP.Keywords: Subconjunctival; Retinopathy of Prematurity; Vascular Endothelial Growth Factor; Oxygen Induced Retinopathy
48 To Study the Effect on Central Foveal Thickness Following Prompt/Deferred Macular Photocoagulation After Single Intravitreal Bevacizumab Injection , Aashka Shah, Vidhi Solanki and Dipal Patel
Abstract Aim:To find out the efficacy of macular photocoagulation when given in the early or late period after single intravitreal bevacizumab injection in terms of central foveal thickness change and visual acuity gain.Methods:40 patient eyes were studied and they were divided into groups based on sex, age, hba1c levels, severity of disease and treatment received over the period of 6 months. Result and Conclusion: Patients receiving deferred macular photocoagulation after a single intravitreal injection of bevacizumab had better outcomes regarding reduction of central foveal thickness and improvement in visual acuity at the end of 6 month observa-tion period compared to those patients receiving prompt macular photocoagulation.
49 A Study of Hypertension and Associated Health Related Life Style Behaviours in Patients with Depression , Varum Malhotra, Hena Dhir1, Rakesh Malhotra, Ankit Daral3 and Rahul Bhargava
Abstract Background: Patients with severe mental illness including depression may have multiple co-morbid physical illnesses. Systemic hypertension and lifestyle factors may increase mortality in patients with depression. Objective: To study co-morbid hypertension and associated lifestyle factors in patients with major depression. Methods: Cross section observational study at a tertiary care hospital. Results: Patients evaluated after exclusion were 400. Majority of patients 69(34.5%) had moderate depression. The mean duration of illness was 58.94 ± 77.26 months with no significant difference between males and females (P = 0.830). Co-morbid psychiatric ill-ness was present in 73(36.5%) study subjects. Co-morbid conditions were present in 106 (26.5%) patients. The prevalence of hyper-tension in our cohort was 18.5%. A total of 216 patients (54%) were found to be obese; it was significantly higher (Chi-square test, P = 0.024) in females (63.7%) as compared to males (47.5%). Inadequate physical activity was seen in 44.5% patients. On correlation analysis, a significant correlation (P<0.05) was observed between hypertension with obesity and family history of non-communi-cable disease. On binary logistic regression, in patients with depression, those with positive family history of non-communicable disease (OR = 2.6), increased duration of illness (OR = 1.3) and physical inactivity (OR = 2.1) were more likely to have hypertension. Conclusion: A bidirectional association may exist between depression and hypertension with increased risk of cardiovascular mor-bidity.
50 Cystic Schwannoma Arising from Supraorbital Nerve Masquerading as a Dermoid: An Unusual Case , Kanishk Singh, Ankur Shrivastava and Amrita Singh
We are presenting a rare case of Cystic Schwannoma which was masquerading as a dermoid .The patient was 23 year old male pre-sented with a slow growing mass over his right supero-medial side of the orbit since last two and a half years. Examination showed a solid, non-tender, freely mobile mass of around 15 × 15 mm in the supero-nasal orbit, which was firm to hard in consistency, non-pulsatile, non-reducible in nature. CT scan of right orbit revealed a well-defined hypo attenuated skin based lesion in the right supra-orbital region which measures 11.9 × 14.6 × 15.2 mm (AP × TRA × CC). A complete tumour resection was performed, and pathologic examination showed it as a case schwannoma of orbit. Schwannomas are infrequent tumours which arise from the orbit coming behind Inflammatory, vascular and lymphoproliferative diseases; treatment is complete resection of the mass with subsequent moni-toring to prevent recurrence.
51 Role of ASOCT in Preoperative Assessment of Posterior Polar Cataract , Abhinav Dhami, Nimratabajaj Dhami and Gobinder Singh Dhami
Abstract Objective: Preoperative anterior segment optical coherence tomography in assessing posterior polar capsule integrity. Method: A prospective observational study of 40 eyes of 25 patients. Patients with posterior polar cataracts undergoing elective cataract surgery were planned for ASOCT [Copernicus Revo (OCT NX700 Optopol technology) and the IOL master 700 (Carl Zeiss Meditec AG, Jena, Germany)] for determining the posterior capsular integrity and planned for phacoemulsification, by two surgeons during the period of January 2019 to December 2019. Posterior polar cataracts were categorized: Type 1- “continuous”; Type 2: abrupt, Type 3: “dehiscent”.Results: A total of 40 eyes (25 patients) were included. 30 eyes (75%) were bilateral (15 patients) and 10 eyes (25%) were unilateral patients. ASOCT findings noted were, type-1 PPC were observed to be 85% (34 eyes) and 70% (30 eyes) equally detected with both the IOL master 700 and the Optopol ASOCT, Type-2 PPC were 12.5% (5) and 15% (6) of the cases and type-3 PPC were 2.5% (1) with the IOL master 700 and 10% (4) with the Optopol Revo ASOCT. The sensitivity and specificity for the IOL master 700 for predicting the PPC integrity was 90.32% and 66.27% each, and for the Optopol REVO ASOCT was 96.77% and 90% each. Intraoperatively, pos-terior capsular rent was noted in type-3 PPC, 2 cases (5%). Conclusion: AS-OCT provides a relevant insight for predicting preoperative PC deficits thus enabling better surgical planning and in anticipating PCR.
