PURPOSE: The purpose of this study is to compare real-world visual acuity (VA) in patients with neovascular age-related macular degeneration (nAMD) treated with a single anti-vascular endothelial growth factor (VEGF) drug monotherapy for 1 year from the American Academy of Ophthalmology (AAO) Intelligent Research in Sight (IRIS) Registry. DESIGN: Retrospective, nonrandomized, comparative study. PARTICIPANTS: IRIS Registry patients with nAMD who received bevacizumab, ranibizumab, or aflibercept only for 1 year between 2013-2016. METHODS: Participants were divided into 3 groups based on monotherapy type. Multivariate analysis of covariance models (ANCOVA) was constructed in a stepwise fashion. MAIN OUTCOME MEASURES: The logarithm of the minimum angle of resolution (logMAR) VA at 1 year and mean change in logMAR VA between baseline and 1 year were compared between drug types. RESULTS: Of 13 859 patients, 6723 received bevacizumab, 2749 received ranibizumab, and 4387 received aflibercept only for 1 year. A total of 84 828 injections were performed. The mean number of injections (standard deviation) at 1 year was higher in the ranibizumab (6.4 [±2.4]) and aflibercept groups (6.2 [±2.4]) compared to bevacizumab group (5.9 [±2.4]; P < 0.0001). In the age-adjusted model, both ranibizumab and aflibercept achieved better logMAR VA at 1 year compared with bevacizumab (0.50 [±0.49], 0.49 [±0.44], 0.55 [±0.57]; P < 0.0001). However, this difference was not significant after multivariate adjustment (age, baseline VA, diabetes, posterior vitreous detachment, number of injections, race, insurance). There was no statistical difference in the age-adjusted or multivariate-adjusted mean logMAR VA change (standard deviation) at 1 year among treatment groups (-0.048 [0.44] bevacizumab, -0.053 [0.46] ranibizumab, -0.040 [0.39] aflibercept; P = 0.46). A higher percentage of patients achieved a ≥3-line VA improvement at 1 year in the bevacizumab group (22.7%) compared with ranibizumab (20.1%; P = 0.0093) and aflibercept (17.8%; P < 0.0001). However, after multivariate adjustment, aflibercept exhibited a greater log odds of a ≥3-line VA loss compared with bevacizumab only (1.25 log odds ratio; P < 0.0016). CONCLUSIONS: This study suggests that all 3 drugs improve VA similarly over 1 year of monotherapy.
