Abstract :
Purpose: To report a case of central retinal artery (CRA) occlusion secondary to prepapillary loop in a 13‑year‑old girl.
Methods: A 13‑year‑old girl presented with a history of sudden visual loss in her left eye.
Results: Fundus examination confirmed thrombosis in a prepapillary arterial loop causing CRA occlusion and extensive retinal ischemia.
Macular region was watered by an anomalous macular branch, which explained her 20/20 vision central vision.
Conclusion: Congenital prepapillary vascular loops are rare and usually asymptomatic. We report a case of central artery occlusion confirmed by multimodal imaging.
