Abstract

Purpose: To identify factors influencing visual outcome in patients with neovascular age-related macular degeneration (NVAMD) and subfoveal hemorrhage (SFH) treated with anti-vascular endothelial growth factor (VEGF) agents.

Design: Retrospective case series.

Methods: Anti-VEGF-treated eyes with SFH > 1 disc area (DA) were identified (n = 16) and changes in visual acuity (VA) and central subfield thickness (CST) from baseline to last follow-up, along with SFH area, thickness, minimum distance from fovea to SFH border, and time to resolution, were determined.

Results: At baseline, mean (± standard error of the mean) size and thickness of SFH were 14.9 ± 2.8 DA and 386.6 ± 46.9 μm, and mean Snellen VA and CST were 20/250 and 591.7 ± 57.0 μm. Median follow-up was 47.6 months. While more than 50% of patients had VA ≤ 20/200 at baseline and all time points through week 48, the percentage of patients with VA ≥ 20/50 increased to 30%-40% at months 6 and 12 and remained stable through month 48. Spearman rank correlation demonstrated 2 independent variables that correlated with good visual outcome, smaller area of SFH at baseline (r = -0.630; P = .009), and high frequency of anti-VEGF injections (r = 0.646; P = .007). In exceptional patients with good visual outcome despite large baseline SFH, shortest distance between the fovea and hemorrhage border significantly correlated with baseline VA (r = -0.503, P = .047) and final VA (r = -0.575, P = .02).

Conclusions: Patients with NVAMD and thick SFH, but short distance between fovea and uninvolved retina, can have good visual outcomes when given frequent anti-VEGF injections.
