Retinal venous macroaneurysm associated with premacular hemorrhage

To report an unusual association of a retinal venous macroaneurysm with pre macular hemorrhage in a 50-year-old man, using a case report method. The pa tient exhibited a dense premacular hemorrhage in the left eye. Fluorescein angiography demonstrated that the source of bleeding was an isolated retina l venous macroaneurysm. The anterior surface of the hematoma was opened wit h an argon green laser, resulting in rapid clearing of the premacular hemor rhage and improvement in vision. Treatment of the retina surrounding the ma croaneurysm to prevent recurrence of bleeding was ineffective to achieve oc clusion of the lesion. No recurrent hemorrhage occurred during the observat ion period, Retinal venous macroaneurysm, a quire rare condition, may be co mplicated by premacular hemorrhage, Argon green laser may be useful in trea ting such hemorrhage. Hemorrhagic detachment of the internal limiting membrane or subhyaloid hemo rrhage in the macula may occur after retinal vessel rupture with physical e xertion (Valsalva retinopathy) or in retinal vascular diseases, such as pro liferative diabetic retinopathy, and retinal arterial macroaneurysm.(1) Art erial macroaneurysms are a common, well-described retinal vascular disorder .(1) In contrast to retinal arterial macroaneurysms, retinal venous macroan eurysms are quite rare.(2,3) In this article we describe a patient who pres ented with premacular hemorrhage that was caused by a retinal venous macroa neurysm. The hematoma and the macroaneurysm were treated with argon green l aser.
