A case is reported of neovascularization of the iris and anterior chamber angle in both eyes of a patient with bilateral occlusion of the temporal branches of the central retinal arteries. Although the etiology of the arteriolar occlusions remains uncertain, blockage secondary to embolization from a mural thrombus in the left ventricle seems most likely. The maintenance of normal intraocular pressure and outflow facility in both eyes, despite rubeosis iridis of at least seven months' duration, is noted. The documentation of this relatively benign course should encourage a careful search for asymptomatic neovascularization of the anterior segment in all patients with any degree of occlusive retinal vascular disease.
