title: Macroaneurysms of the retinal arteries.
abstract: Six patients with spontaneous retinal and/or vitreous hemorrhages were found, on evaluation by fluorescein angiography, to have macroaneurysms involving the major retinal arteries. All showed evidence of other vascular disease. With absorption of the hemorrhages, five patients experienced appreciable improvement in vision. The aneurysms appeared to diminish in size as a result of fibrous changes within the arterial walls. In one patient, however, a second vitreous hemorrhage occurred several months later. The possibility of repeated hemorrhage suggests that more consideration should be given to treatment of these aneurysms.
