OCT and ultrasound biomicroscopic findings in iris arteriovenous malformation.

Iris arteriovenous malformation, also labeled as iris racemose hemangioma, is a rare condition in which abnormal vessels are present on the iris surface. Slit-lamp findings in addition to anterior segment fluorescein angiographic features of such lesions have been described in the past. The authors report anterior segment optical coherence tomography and ultrasound biomicroscopic features in two patients with iris arteriovenous malformation.
