title: Retinal venous macroaneurysm associated with premacular hemorrhage.
abstract: To report an unusual association of a retinal venous macroaneurysm with premacular hemorrhage in a 50-year-old man, using a case report method. The patient exhibited a dense premacular hemorrhage in the left eye. Fluorescein angiography demonstrated that the source of bleeding was an isolated retinal venous macroaneurysm. The anterior surface of the hematoma was opened with an argon green laser, resulting in rapid clearing of the premacular hemorrhage and improvement in vision. Treatment of the retina surrounding the macroaneurysm to prevent recurrence of bleeding was ineffective to achieve occlusion of the lesion. No recurrent hemorrhage occurred during the observation period. Retinal venous macroaneurysm, a quite rare condition, may be complicated by premacular hemorrhage. Argon green laser may be useful in treating such hemorrhage. Hemorrhagic detachment of the internal limiting membrane or subhyaloid hemorrhage in the macula may occur after retinal vessel rupture with physical exertion (Valsalva retinopathy) or in retinal vascular diseases, such as proliferative diabetic retinopathy, and retinal arterial macroaneurysm. Arterial macroaneurysms are a common, well-described retinal vascular disorder. In contrast to retinal arterial macroaneurysms, retinal venous macroaneurysms are quite rare. In this article we describe a patient who presented with premacular hemorrhage that was caused by a retinal venous macroaneurysm. The hematoma and the macroaneurysm were treated with argon green laser.
