Abstract
Fundus autofluorescence (FAF) is a noninvasive imaging tool helpful in various retinal and choroidal diseases. In this series, we report the utility of FAF in two cases of retinal artery occlusion (RAO). Cholesterol embolus was seen as a bright hyper autofluorescent foci on FAF in a case of branch RAO. Platelet fibrin embolus exhibited minimal hyper autofluorescence in another case of multiple RAO in contrast to bright hyper autofluorescence of cholesterol embolus. Fundus autofluorescence may be helpful in easier identification of cholesterol embolus in RAO and helps in differentiating it from platelet fibrin embolus.
