In the acute stage of VKH, fundus examination reveals small nodules at the level of the RPE, known as Dalen-Fuchs nodules, in the posterior pole (a). Fluorescein angiography (b) illustrates multifocal areas of punctate hypofluorescence with late staining or leakage and central pooling within the subretinal fluid. Indocyanine green angiography (c) indicates active inflammation at the level of the choroid as evidenced by the hypofluorescent dark spots. 3 × 3 mm (d) and 6 × 6 mm (e) optical coherence tomography angiography illustrates areas of flow void at the level of the choriocapillaris (d, e) proving that the choriocapillaris is involved and ischemic
