Purpose: To study efficacy of anti-vascular endothelial growth factor (anti-VEGF) in resolution of macular edema in epidemic retinitis (ER). Methods: In this retrospective, comparative study, patients diagnosed as ER with central macular thickness (CMT) ≥ 600 μm on SD-OCT at presentation were studied. Eyes which did not receive intravitreal anti-VEGF formed group A and eyes receiving additional anti-VEGF formed group B. Eyes receiving anti-VEGF monotherapy were studied separately. Cases with subsequent OCT scans with interval of more than 20 days and cases without OCT scan at the resolution were excluded. Treatment details, visual outcome, and days to resolution of macular edema were studied. Results: Mean CMT in group A (n = 8) was 820.1 μm (range 607-1004 μm) and in Group B (n = 4) was 756.0 μm (range 603-1000 μm). Macular edema resolved in 34.8 days (range: 16-65) and 39.0 days (range: 21–45) in group A and B, respectively. Two eyes with anti-VEGF monotherapy recovered in 45 and 18 days, respectively. Mean corrected distance visual acuity (CDVA) at presentation in group A was 19.1 (range: 0–61) ETDRS letters and in group B was 14.3 (range: 0–35) ETDRS letters. Mean CDVA improved to 65.7 (range: 0–85) and 50.8 (range: 20–76) ETDRS letters in group A and B, respectively. Anti-VEGF monotherapy eyes improved from 35 and 46 ETDRS letters to 70 and 85 ETDRS letters, respectively. Conclusion: Additional anti-VEGF therapy has no added advantage in speed of resolution of macular edema due to ER. A randomized controlled trial with steroids sparing “anti-VEGF monotherapy” may verify our observations.
