PURPOSE: To report a rare case of kearns sayre syndrome.
METHOD: A 15 yr old male child presented with drooping of left upper eyelid since one year.
RESULTS: Ocular examination,BCVA was Log MAR 0.2 in BE. BE had ptosis with mild ptosis in right eye and a severe ptosis in the left eye with poor LPS function. There was restriction in extraocular movements of both eyes especially in elevation. Fundoscopy revealed a characteristic salt and pepper background.
