Abstract:
The prepapillary vascular loops are rare congenital vascular anomalies. Often unilateral and asymptomatic, they may be complicated by ischemic events by twisting or thrombosis of the loop. We report a rare case of double prepapillary arterial loop complicated by left retinal ischemia due to thrombosis of the loop.
