PURPOSE: To evaluate the proportion, predictors, and outcomes of patients with neovascular age-related macular degeneration (nAMD) treated with a high burden of VEGF inhibitor intravitreal (IVT) injections after 2 years in routine clinical practice. DESIGN: Retrospective analysis of data from a prospectively designed observational outcomes registry, the Fight Retinal Blindness! Project, of patients treated in European centers. PARTICIPANTS: Treatment-naïve eyes (1 eye per patient) starting VEGF inhibitors for nAMD from January 2017 to March 2020 with 24 months of follow-up. We analyzed the following 3 treatment-burden groups defined by the mean interval of the 3 closest injections to the 24-month visit: (1) those with a high-treatment burden had injection intervals ≤ 42 days, (2) those with a low-treatment burden had injection intervals between 43 and 83 days; and (3) those with tolerable treatment burden had injection intervals between 84 and 365 days. METHODS: Multinomial regression was used to evaluate baseline risk predictors of patients requiring a high-treatment burden. MAIN OUTCOME MEASURES: The proportion of patients that experienced a high-treatment burden at 2 years and its predictors. RESULTS: We identified 2038 eligible patients completing 2 years of treatment (2038/3943 patients [60%]) with a median (quartile 1, quartile 3) of 13 (10, 17) injections. The proportion of patients with a high-treatment burden was 25% (516 patients) at 2 years. Younger patients (odds ratio [OR], 0.97; 95% confidence interval [CI], 0.96-0.99; P < 0.01) were more likely to have high-treatment burden, whereas eyes with type 3 choroidal neovascular lesions at baseline were significantly less likely (OR, 0.26; 95% CI, 0.13-0.52; P < 0.01). Regarding type of fluid, patients with subretinal fluid only at baseline (OR, 3.85; 95% CI, 1.34-11.01; P = 0.01) and persistent active intraretinal (OR, 1.56; 95% CI, 1.18-2.06; P < 0.01) or subretinal fluid only (OR, 2.21; 95% CI, 1.52-3.21; P < 0.01) after the loading phase had a higher risk of high treatment burden at 2 years. CONCLUSIONS: High treatment burden is a common issue in routine clinical practice in Europe, with a quarter of patients requiring injections of conventional VEGF inhibitors every 6 weeks at 2 years and 40% discontinuing treatment within 2 years.
