Retinal Arteriovenous Malformation (AVM): A Case Report

A retinal AVM is a rare, unilateral, nonhereditary congenital anomaly with variable presentation and variable visual involvement. Presentation can vary from subtle arteriovenous communications to marked dilation of the entire retinal vascular system. Most commonly involved areas are papillomacular and the superotemporal retina. We describe a case of 22 year old male patient presented with complaint of decreased vision in right eye. Fundus examination showed multiple dilated tortuous vessels involving whole of the Retina of right eye, including disc and macula. Left eye was within normal limits. No other systemic involvement was noted. Detailed evaluation and further follow-up is necessary because of associated systemic conditions and CNS anomalies.
