PURPOSE: To evaluate the efficacy of intravitreal ranibizumab (IVR) for subfoveal polypoidal choroidal vasculopathy (PCV) in eyes with a best corrected visual acuity (BCVA) of 0.6 (logMAR 0.22) or better. METHODS: Fifty eyes with BCVA between 0.6 (logMAR 0.22) and 1.0 (logMAR 0) and subfoveal PCV were treated with IVR for 3 consecutive months. Additional IVR was given at subsequent monthly visits, if needed, up to 11 months after the initial injection. The patients were followed-up prospectively for 12 months, and changes in mean BCVA, central retinal thickness (CRT), serous retinal detachment (SRD), hemorrhage, and number of polypoidal lesions were evaluated. RESULTS: Mean BCVA improved significantly at the 3-, 6-, 9-, and 12-month follow-up visits and CRT decreased significantly at 1, 2, 3, 6, 9, and 12 months after the initial treatment as compared with the baseline. SRD was observed in 10 and 21 eyes at 3 and 12 months. Hemorrhage was observed in 6 eyes at 3 months and 3 eyes at 12 months. All polypoidal lesions had completely regressed in 19 % and the size of network vessels was either unchanged or enlarged in 98 % of the eyes at 12 months. CONCLUSION: Based on the maintenance of vision improvement for at least 12 months, IVR for PCV proved useful for eyes with BCVAs of 0.6 (logMAR 0.22) to 1.0 (logMAR 0), despite a low regression rate of polypoidal lesions and minimal network size reduction.
