Abstract
PURPOSE: To report a case of branch retinal artery occlusion and prepapillary loop in a 10-year-old girl. METHODS: Case report with funduscopic and fluorescein angiography imaging. RESULTS: A 10-year-old girl presented with a history of the sudden onset of a superior visual field defect in her right eye. Fundus findings were consistent with thrombosis in a prepapillary arterial loop causing an inferior branch retinal artery occlusion. CONCLUSION: Bilateral congenital prepapillary vascular loops are rare, and are usually asymptomatic. However, they can be complicated by vitreous hemorrhage and thrombosis. Such thrombotic events may be precipitated by hemodynamic or intravascular changes associated with exercise.
