Fundus photography, combined fluorescein angiography (FA) and indocyanine green angiography (ICGA), and optical coherence tomography angiography (OCTA) of a patient with acute Vogt-Koyanagi-Harada (VKH) disease (subject #3). Fundus photograph (a) shows presence of vitritis with multiple yellowish choroiditis lesions in the posterior pole. Combined FA and ICGA in the early frame (b) shows early pin-point hyperfluorescence on FA and multiple hypocyanescent lesions on ICGA. In the late frame (d), there is progressive hyperfluorescence with pooling of the dye on FA and persistence of hypocyanescent lesions on ICGA suggestive of choriocapillaris ischemia. The en face OCTA (c) at the level of choriocapillaris shows presence of multifocal dark spots which are variably sized and corresponded to the hypocyanescent lesions on ICGA. Few such dark foci have been demarcated with yellow dashed line. The structural en face OCT scan shows only mild signal loss in the area of subretinal fluid but no loss in the areas of dark spots (e). The corresponding cross-sectional OCT B-scan (f) shows presence of subretinal fluid
