PURPOSE: To report features of neovascular age-related macular degeneration (AMD) in Brazilian patients. PROCEDURES: Data were prospectively collected from patients diagnosed with neovascular AMD. Eyes were classified as having typical neovascular AMD, polypoidal choroidal vasculopathy (PCV), or retinal angiomatous proliferation (RAP). RESULTS: In total, 265 eyes of 207 patients of predominantly Caucasian ancestry were included; 166 (62.6%) eyes had typical neovascular AMD, 65 (24.5%) eyes had PCV, and 34 (12.8%) eyes had RAP. RAP demonstrated a higher percentage of bilateral cases (p = 0.015). The mean foveal subfield thickness was significantly lower in eyes with PCV (p < 0.001). Cases with typical neovascular AMD had a higher percentage of predominantly classic and minimally classic lesions on fluorescein angiography (FA; p = 0.005). CONCLUSIONS: In Brazilian patients, PCV and RAP represented 24.5 and 12.8% of neovascular AMD cases. Neovascular AMD subtypes differ in relation to clinical features, mean foveal subfield thickness and FA presentation.
