A 26-year-old man presented for a routine examination. His visual acuity and anterior segments were normal in both eyes. Fundus examination of the right eye showed a large arteriole and venule arising from the main vascular trunk at the disc and crossing the macula [Figure 1]a. Fluorescein angiography showed dilatation of the capillary bed around these vessels with sparing of the foveal avascular zone [Figure 1]. | Figure 1: Fundus photograph of the right eye showing a large arteriole and venule arising from the main vascular trunk at the disc and crossing the macula (a). Fluorescein angiography showing early filling of the aberrant vessels with dilatation of the surrounding capillary bed. Foveal avascular zone is relatively spared (b)

Congenital macrovessel is a rare vascular malformation which is usually unilateral and asymptomatic.[1] Rare complications include macular hemorrhage, macular edema, macular ischemia, branch retinal artery occlusion, and angioscotoma.[2],[3],[4] There have been associations with cerebrovascular anomalies.[4]
