BOOK TITLE: Retina: Medical and Surgical Management
Retinal arterial macroaneurysm is a fusiform or saccular dilatation of the retinal arterioles that usually arises within the first three orders of bifurcation. Retinal artery macroaneurysm typically occurs in elderly hypertensive women. Females are three times more commonly affected than males. Retinal arterial macroaneurysms may be found in asymptomatic patients on routine examination. In acute form, patient presents with a sudden loss of vision due to retinal or vitreous hemorrhage. Fundus Fluorescein angiography, indocyanine green angiography, and optical coherence tomography are investigations options for retinal arterial macroaneurysms. Treatment of retinal artery macroaneurysm depends on the clinical presentation. Patients with asymptomatic aneurysm without leakage should be treated conservatively with close follow-up. Macroaneurysms that have regressed/fibrosed spontaneously with or without rupture and hemorrhage could be observed without active intervention as these macroaneurysms rarely rebleed. Intervention in cases with retinal artery macroaneurysm includes treatment targeted to the macroaneurysm, treatment for macular edema and treatment of secondary complications
