Retinal Arterial Macroaneurysms

Abstract

Aneurysmal alterations of the retinal vasculature are a frequent finding in clinical ophthalmic practice. These changes most commonly involve the retinal veins or capillaries and are usually seen as a sequel to diabetes mellitus, venous occlusive disease, sickle cell disease, or radiation retinopathy. Less commonly, larger aneurysms arise directly from the major retinal arteries. Although mentioned sporadically in the earlier literature [1, 2], the entity currently known as retinal arterial macroaneurysms was formally described in 1973 by Robertson [2].
