Retinal arterial macroaneurysms.
Retinal arterial macroaneurysm is a distinct, infrequently occurring fundus sign usually found in older patients with systemic vascular disease. The lesion arises on a main branch of the retinal artery within the first three orders of bifurcation. Visual disturbance is uncommon, although it may occur as a result of vitreous or retinal hemorrhage or macular edema. This paper presents two cases of retinal arterial macroaneurysm and discusses the diagnosis, etiology, and management of this condition.
