Abstract

PURPOSE. To examine the baseline factors associated with good (20/60 or better) versus poor (20/200 or worse) visual outcomes in eyes with treatment-naïve neovascular age-related macular degeneration (AMD) receiving intravitreal antivascular endothelial growth factor (VEGF) on a treat-and-extend regimen (TER). METHODS. An observational, retrospective series of patients managed with a TER, identified as having either good or poor visual outcomes, was examined. A multivariate regression analysis of baseline characteristics identified factors associated with good and poor vision at 2, 3, and 4 years. Neovascular subtypes were identified using fluorescein angiography (FA) alone and the anatomic classification system with FA and optical coherence tomography (OCT). RESULTS. One hundred thirty-eight patients (154 eyes) fit the inclusion criteria at 2 years, 106 patients (113 eyes) at 3 years, and 72 patients (74 eyes) at 4 years. In the multivariate analysis, type 1 lesions, according to anatomic classification, had better vision at 24 months (95% CI: [3.1, 82.7], P = 0.01), 36 months (95% CI: [1.97, 24.17], P = 0.003), and 48 months (95% CI: [2.01, 65.47], P = 0.006). Clopidogrel use was associated with poor vision at 24 months (95% CI: [0.03, 0.68], P = 0.013). Vision at 3 months was the best predictor of vision at year 4 (b = -4.277, P = 0.002). CONCLUSIONS. Eyes with neovascular AMD managed with a TER of anti-VEGF therapy having type 1 neovascularization at baseline were more likely to maintain good vision over 4 years, whereas clopidogrel use predicted poor vision at 2 years. Vision at 3 months was the best predictor for favorable long-term vision.
