Purpose: To assess visual and optical coherence tomography-derived anatomical outcomes of treatment with intravitreal aflibercept (Eylea®) for diabetic macular oedema in patients switched from intravitreal ranibizumab (Lucentis®).
Design: Retrospective, cohort study.
Participants: Ninety eyes (of 67 patients) receiving intravitreal anti-vascular endothelial growth factor therapy were included.
Methods: This is a retrospective, real-life, cohort study. Each patient had visual acuity measurements and optical coherence tomography scans performed at baseline and 12 months after the first injection of aflibercept was given.
Main Outcome Measures: We measured visual acuities in Early Treatment Diabetic Retinopathy Study letters, central foveal thickness and macular volume at baseline and at 12 months after the first aflibercept injection was given.
Results: Ninety switched eyes were included in this study. The mean (standard deviation) visual acuity was 63 (15.78) Early Treatment Diabetic Retinopathy Study letters. At baseline, the mean (standard deviation) central foveal thickness was 417.7 (158.4) μm and the mean macular volume was 9.96 (2.44) mm. Mean change in visual acuity was +4 Early Treatment Diabetic Retinopathy Study letters (p = 0.0053). The mean change in macular volume was -1.53 mm in SW group (p = 0.21), while the change in central foveal thickness was -136.8 μm (p = 0.69).
Conclusion: There was a significant improvement in visual acuity and in anatomical outcomes in the switched group at 12 months after commencing treatment with aflibercept for diabetic macular oedema.

Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, Miami, FL.
Purpose: The purpose of this study was to report the management of chemoimmunotherapy-resistant ocular surface squamous neoplasia (OSSN) with iodine-125 (I-125) brachytherapy.
Methods: A 36-year-old man presented to the clinic with biopsy-proven OSSN that covered ∼70% of the corneal surface and extended to the 6 o'clock position of the inferior limbus of the OS. The visual acuity was 20/20 in the OD and 20/40 in the affected OS.
Cataract surgical coverage in Indian population aged 50 years and above.

Dr Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences (AIIMS), New Delhi, India.
Objectives: The objectives of the study were to obtain the current estimates of cataract surgical coverage (CSC) at varying thresholds of vision and gender variations across districts in diverse Indian populations aged ≥50 years.
Methods: Data collected from the national blindness survey from 31 Indian districts between 2015 and 2019 were analyzed. CSC at varying thresholds of presenting visual acuity <3/60, <6/60, and <6/18 were estimated along with gender variations across districts in population ≥50 years of age.
