Fundus photograph (A), a late phase (10 minutes and 55 seconds) image of fluorescein angiography (B), and montaged images of horizontal (C) and vertical (D) EDI-OCT scans in the right eye with acute Vogt–Koyanagi–Harada disease. Dramatic choroidal thickening in the area of macular serous retinal detachment obscures the chorioscleral boundary (asterisk in C and D). Choroidal thickening is also noted in the periphery in the absence of overlying retinal edema. The wide dark zone, possibly indicating exudative fluid accumulation, is delineated in the suprachoroidal space in the temporal periphery (arrows in C). A notable finding is the undulations and bumps on the RPE surface associated with the irregular thickening of the choroid when compared with a normal choroidal configuration in Figure 4. The multiple small undulations (or folds) of the RPE surface are evident in the vertical scan (D) and correspond to the horizontal folds seen in the fundus photograph (black arrows in A). Although serous retinal detachment is clearly located in the macula, choroidal pathology is also evident in the periphery.
