This 37 year old was found to have a prominent iris vessel on his right iris during a routine examination. This vessel was found to be non-leaking on fluorescein angiography. This patient has arterial venous malformation of the iris. A series of 14 cases were published by Shields, et. al., in the Archives of Ophthalmology, Vol. 124, pp. 370-375, 2006. To quote Dr. Shields “Iris AV malformation has characteristic clinical and fluorescein angiographic features. It appears to be a benign stationary condition that has no apparent systemic associations and no local complications.”
