Purpose: To evaluate 1-year outcomes of intravitreal injections of aflibercept (IVA) in Japanese polypoidal choroidal vasculopathy (PCV) patients. Methods: In this prospective, open-label, single-arm multicenter clinical trial, treatment-naïve PCV patients received IVA (2.0 mg) every 2 months, after 3 initial monthly doses. The primary endpoint assessed was the proportion of patients maintaining baseline best-corrected visual acuity (BCVA) at 1 year. Results: Fifty eyes with PCV were included in the study. BCVA was maintained or improved in 97.6% of the patients. Mean logMAR BCVA at baseline was 0.33, and had improved to 0.12 logMAR 1 year after the initiation of aflibercept treatment (p < 0.001). Mean central foveal thickness decreased from 356 to 239 μm (p < 0.001). Complete regression of polypoidal lesions was seen in 72.5% after 1 year of treatment. Conclusions: One year of IVA resulted in stabilization of BCVA and anatomical improvement in Japanese PCV patients.
