Arteriovenous malformations of the iris

This is the first report in the American literature elaborating on the clinical and angiographic characteristics of an iris arteriovenous malformation. Iris vascular abnormalities that do not leak fluorescein have previously been described only in association with underlying disorders. Iris arteriovenous malformations must be differentiated from neovascularization and other diseases affecting iris vasculature in which treatment is necessary in order to prevent further sequelae.
