    Indocyanine Green Dye Filling Time for Polypoidal Lesions in Polypoidal Choroidal Vasculopathy Affects the Visibility of the Lesions on OCT Angiography

    Purpose To elucidate the factors that affect the visibility of polypoidal lesions on OCT angiography (OCTA) based on indocyanine green angiography (ICGA) findings in eyes with polypoidal choroidal vasculopathy (PCV). Design Retrospective, consecutive case series. Participants Thirty-one eyes of 31 patients with PCV diagnosed on ICGA. Methods We compared the numbers of polyps visible on ICGA and on OCTA. The following time points and durations were determined: first appearance of dye in the choroidal arteries, first appearance of dye within a polyp, and the time it took the dye to fill entire lesions. Then we compared visible and invisible polyps ...
