Regression of outer retinal abnormalities on OCT preceding the recovery of choroidal perfusion abnormalities on ICG-A. a-b Combined ICG-A and OCT during the ongoing process of remission. The restoration of outer retinal abnormalities is detectable with OCT, as shown in the right part of a and b images, while persistent patchy hypofluorescences can be identified in the corresponding locations with ICG-A, as shown in the left part of the images (the green orizontal lines crossing the ICG-A images highlight examples of persisting focal non-perfused areas, while the vertical lines crossing the OCT images represent the corresponding locations). c ICG-A in the inactive stage of disease showing the regression of patchy hypofluorescences; green arrows indicate the locations corresponding to previous focal hypoperfusion areas in a and b images
