Answer

In the acute phase, fundus autofluorescence in ischemic areas is decreased because of retinal edema blocking the normal RPE. Eventually, this could return to normal baseline or may be associated with increased autofluorescence owing to a window defect created by the thinned-out inner retinal layers. [24]
