The causative organism isolated was similar to that documented in other reports. Endophthalmitis must be treated with vitrectomy and intra-vitreal injections of antibiotics after a proper vitreous tap.

Purpose: To compare the post-cataract endophthalmitis (PCE) rates among eyes undergoing syringing or regurgitation on pressure over the lacrimal sac (ROPLAS) test prior to cataract surgery. Methods: We performed a single-center, retrospective, comparative analysis of eyes developing PCE who underwent syringing prior to cataract surgery (group A) in the pre-COVID-19 era between November 1 2019 and January 31, 2020 and the eyes that underwent ROPLAS test prior to cataract surgery (group B) in the COVID-19 era between November 1, 2020 and January 31, 2021. Results: A total of 87,144 eyes underwent cataract surgery during the two time periods of the study. Syringing was performed in 48,071 eyes, whereas ROPLAS was performed in 39,073 eyes. In group A, 19 eyes (0.039%) developed PCE, whereas 20 eyes (0.051%) developed PCE in group B ( P = 0.517). Between the two groups, the grade of anterior chamber cellular reaction ( P = 0.675), hypopyon ( P = 0.738), and vitreous haze ( P = 0.664) were comparable. Gram-positive organisms were detected in 4 eyes in group A and 6 eyes in group B; 2 eyes in group A had gram-negative bacilli. The presenting visual acuity (Group A: LogMAR 1.42 and Group B: LogMAR 1.30) and final visual acuity (Group A: LogMAR 0.52 and Group B: LogMAR 0.5) were comparable between the two groups. ( P = 0.544 and 0.384, respectively). Conclusion: The rates of PCE were comparable among the eyes undergoing either syringing test or ROPLAS prior to cataract surgery.
