This case report describes an uncommon presence of a retinal arterial macroaneurysm complicated by retinal neovascularization.This is a case history of a 49-year-old woman presenting with preretinal, intraretinal, and subretinal hemorrhage with an adjacent retinal arterial macroaneurysm complicated by the development of retinal neovascularization.The neovascularization, intraretinal lipid, and retinal and preretinal hemorrhage resolved after laser photocoagulation, topical steroids, and nonsteroidal antiinflammatory agent treatment.The rapid development of a large frond of neovascularization is atypical for retinal arterial macular aneurysms and has not been previously reported.
