Long-term data of intravitreal injections of vascular endothelial growth factor (VEGF) inhibitors are lacking.
This study aims to assess visual and anatomic outcomes of eyes with neovascular age-related macular degeneration (nAMD) after 10 years of anti-VEGF therapy.
Retrospective analysis of data from a prospectively designed database.
116 eyes with nAMD (94 participants) that started anti-VEGF therapy at least 10 years earlier.
Eyes were tracked by the Fight Retinal Blindness! registry.
Mean change in visual acuity at 10 years vs baseline. Visual acuity was assessed by the number of letters read on a logarithm of the minimum angle of resolution chart.
Eyes received a median of 27.5 injections over 10 years. Mean visual acuity was 57.5 letters (SD 17.5) at baseline. It increased slightly at 1 year, then dropped steadily by 18 letters (95% CI: 13.7; 22.3) at 10 years. Overall, 10% of eyes gained ≥10 letters, 64% lost ≥10 letters and 23% remained stable (±5 letters from baseline). Geographic atrophy and subretinal fibrosis were found in 93% and 71% respectively after 10 years, both mostly affecting the centre of the fovea. Pre-treated eyes (47.5%) had significantly worse visual acuity than treatment-naïve eyes at baseline and during follow-up and were significantly more likely to have atrophy and fibrosis.
Despite short-term stabilization, long-term visual outcomes of nAMD eyes under anti-VEGF therapy may be poor. Development of atrophy and fibrosis, resulting from the natural progression of the disease, may partly explain this evolution. This article is protected by copyright. All rights reserved.
