ABSTRACT
PURPOSE: To determine the outcomes of intentionally suspending anti-vascular endothelial growth factor (anti-VEGF) injections in eyes with advanced neovascular age-related macular degeneration (nAMD). DESIGN: Retrospective cohort study. METHODS: The study sample comprised 93 patients with nAMD and best available Snellen visual acuity (VA) ≤20/400 in which anti-VEGF treatment was suspended by the treating physician. VA and optical coherence tomography (OCT) characteristics were evaluated to determine visual and anatomical outcomes up to 24 months after treatment suspension. RESULTS: A total of 93 eyes from 93 patients who had received a mean of 16 anti-VEGF injections over a mean of 962 (SD 562) days were included. Comparing the treatment suspension visit to 24 months later, no significant change in mean central foveal thickness (163 [SD 118, range 19-704] µm vs 164 [SD 217, range 19-1468], P = .97), greatest lesion diameter (2547 [SD 1294, range 134-5707] µm vs 2442 [SD 1158, range 421-5305] µm, P = .43), greatest lesion thickness (194 [SD 136, range 0-618] µm vs 205 [SD 131, range 0-573] µm, P = .40), or VA (1.87 [SD 0.37], 20/1482, vs 1.94 [SD 0.28], 20/1741, P = .16) was found. In total, 7 eyes (7.5%) restarted treatment following a mean of 977 (SD 450) days after treatment suspension. CONCLUSIONS: Suspension of anti-VEGF injections in eyes with advanced nAMD and VA ≤20/400 may be reasonable in cases where the treating physician deems additional treatment is unlikely to provide benefit. Although the visual and anatomical findings remained stable after treatment suspension in most, a small number restarted anti-VEGF therapy, suggesting that eyes should still be monitored for disease progression.
