title: Peripapillary arterial loop--case report.
abstract: Peripapillary arterial loops are uncommon congenital retinal arterial anomalies, which are characterized by retinal arterial loops that originate and terminate on the retina beyond the optic disc borders. We report a case of peripapillary arterial loop associated with preretinal and vitreous hemorrhage. The fluorescein angiography demonstrates the arterial loop and leakage from the loop and its capillaries. The origin of hemorrhage of peripapillary arterial loop might result from the loop and its adjacent capillaries.
