Congenital retinal arteriovenous malformation¹ is a rare, unilateral, nonhereditary disorder with variable visual impairment depending on the severity of the vascular anomaly. Most cases do not show any anatomical progression.² Venous occlusion, intraretinal or vitreal hemorrhage,³ or optic atrophy² are rare causes of sudden or gradual visual loss. We describe the case of a child with visual loss caused by slow progression of a foveal vascular loop and relative amblyopia.

Report of a Case

A 6-year-old boy had deteriorating vision 1 year after the incidental detection of a retinal arteriovenous malformation in his right eye (Figure 1). At the time of the initial detection, his visual acuity was 20/20 OU. One year later, his visual acuity was 20/60 OD and 20/20 OS. Multiple dilated and tortuous vessels emerged from the right optic disc (Figure 2) with 1 superotemporal loop reaching the fovea. No retinal thickening, exudates, bleeding, or relative afferent . . .
