Purpose: To ascertain ophthalmologist‘s perceptions about webinars as a method of continued medical education during the COVID-19 pandemic. Methods: In a cross-sectional study, a 21-question survey was circulated using digital media platform to approximately 1400 ophthalmologists in India between 16 th August 2020 to 31 st August 2020. The questionnaire focussed on the quality and usefulness of webinars based on the Bloom‘s taxonomy. The responses (on 4- or 5-point Likert scale) were analyzed among three professional groups- ophthalmologists in-training, consultants in public sector, and private practitioners. Results: 393 ophthalmologists participated in the survey, with a response rate of 28%. The mean age was 34.6 ± 9.7 years, and males constituted 49.6% (199/393) of the respondents. Forty-seven percent of the respondents perceived the quality of webinars as good or excellent (185/393), 72.8% reported knowledge gain from webinars (286/393), and 63.9% felt that webinars are important in clinical practice and should continue post-COVID-19 pandemic (251/393), with distinct responses among the professional groups. The drawbacks perceived were overt number of webinars (371; 94.4%), confusion regarding which webinars to attend (313; 79.6%), repetition of the information (296; 75.3%), limited opportunity for participant interaction (146; 37.2%) and disparate weightage to the core disciplines of Ophthalmology. Conclusion: Most respondents had favorable perceptions of Ophthalmology webinars happening during the COVID-19 pandemic. However, there is need for improvisation in the volume of webinars, target-audience-based delivery, and participant interaction to add value to this new dimension of teaching-learning.

PURPOSEThe aim of this study was to assess bleb function using Wuerzburg bleb classification score (WBCS) for bleb morphology on slit lamp, intraocular pressure (IOP), and gonioscopy.METHODSA total of randomly selected 30 eyes posttrabeculectomy were assessed for bleb function with the trio of bleb morphology, IOP, and gonioscopy. Bleb was assessed using the WBCS of 0–12 on slit lamp, IOP was assessed using applanation tonometry, and visualization of inner ostium and iridectomy were assessed using gonioscopy. Postoperative patients of less than six weeks were excluded from the study.RESULTSThe correlation between WBCS and the duration of trabeculectomy was found to be highly significant (P value = 0.029). The correlation of IOP with WBCS was also found to be strongly positive (P = 0.000). IOP was found to be highly associated with peripheral iridectomy (P = 0.000), internal window (P = 0.001), and bleb characteristics.

Purpose: Pterygium is a triangular fibrovascular subepithelial ingrowth of degenerative bulbar conjunctival tissue over the cornea. It is now considered to be a result of uncontrolled cellular proliferation as overexpression of p53 protein and Ki-67 nuclear protein was found in the epithelium. This study was done to find the expression of p53 and Ki-67 with the severity and duration of the pterygium to explain the etiopathogenesis. Methods: Data were analyzed from 43 Indian participants of all age groups. All patients were divided according to the severity of pterygium (mild, moderate, and severe groups) and according to the duration of pterygium (<4 years and >4 years). The samples were studied by immunohistochemistry by using antibodies against p53 and Ki-67 proteins considering >5% expression as significant. Results: Of 43 cases, p53 and Ki-67 expression were positive in 33 cases. In mild, moderate, and severe cases p53 positivity was 33.3%, 78.4%, 100%, respectively. P53 expression increased with duration, 79.3% positive in <4 years, and 92.9% positive in >4 years. With increasing severity of pterygium, mild, moderate, and severe cases, Ki-67 positivity was 66.7%, 78.37%, 66.7%, respectively. Ki-67 expression with duration, 79.3% positive in <4 years, and 85.7% positive in >4 years of the duration of pterygium with no statistical significance. Conclusion: Our study revealed that with increasing duration and severity of pterygium, p53 expression was observed to be increasing. Ki-67 expression increased with the duration of pterygium but not with the severity.
