Retinal arteriolar macroaneurysms are a common cause of vision loss in elderly patients with hypertension and cardiovascular disease. Their occurrence in the young, however, is not well known. The purpose of this article is to describe an unusual cause of retinal arteriolar macroaneurysm in a healthy young man.

Case report

A 30-year-old man presented with preretinal hemorrhage and macular exudation due to ruptured retinal artery macroaneurysm. The patient was treated with intravitreal bevacizumab and laser photocoagulation to the macroaneurysm. The exudation and preretinal hemorrhage resolved over several months. Fluorescein angiogram at this stage revealed a congenital anomalous retinal artery.


Congenital anomalous retinal artery may be associated with retinal artery macroaneurysm even in the young age in the absence of any other predisposing factors. The presentation and treatment of such retinal artery macroaneurysm, however, may remain the same to those that occur in older patients.
