Research progress in the treatment of retinal arterial macroaneurysm

Abstract

The retinal arterial macroaneurysm, also known as isolated aneurysm, is an acquired retinal vascular abnormality, which is characterized by fusiform or circular dilatation of the posterior polar retinal arteries, forming one or more aneurysms. Most of aneurysms are located on the temporal vessels of the retina. There are no clinical symptoms in the early stage. If the tumor ruptures and hemorrhage involving the macula, may suddenly appear central dark spots and vision loss. The hemorrhage may be located in the vitreous cavity, under the posterior vitreous boundary membrane, under the retinal inner boundary membrane, and subretinal region. Treatments for RAM include retinal laser photocoagulation, vitrectomy, intravitreal or intraretinal injection of tissue plasminogen activator, and anti-VEGF agent. In this paper, the latest research progress in the treatment of RAM is discussed and prospected.
