A 10-year-old boy noted gradual visual loss in the left eye and sought medical advice. His vi-sion was 1.2 in the right eye and 0.4 in the left. Numerous dots of yellowish-white exudates and edema were seen in the macular area in the left eye. Also, retinal vessels showed marked dilata-tion and tortuosity with arteriovenous loop for-mations. Fluorescein angiography confirmed arte-rio-venos anastomoses and showed generalized dye leakage.The right eye was unaffected. Patches of simple angioma were present on the left fore-head. Other physical, neurological and labora-tory findings were within normal ranges.
