title: Evolution of a retinal arterial macroaneurysm.
abstract: A 58-year-old hypertensive male developed a superior temporal branch vein occlusion in the left eye in 1979. Fluorescein angiography documented the venous occlusion, as well as normal arterial flow. Subsequent laser photocoagulation was performed for cystoid macular edema. In 1981 the patient developed a pre- and sub-retinal hemorrhage in the left eye due to a retinal arterial macroaneurysm in the superior temporal quadrant. Fluorescein angiography documented normal retinal arterial blood flow in the affected vessel at the time of development of the macroaneurysm, but the vessel subsequently occluded. This case adds to the scant literature documenting the evolution of a retinal arterial macroaneurysm.
