This patient has benign congenital prepapillary vascular loops, which can be unilateral or bilateral.
Learning Points:
Although usually just an incidental finding, they can rarely cause a branch arterial or venous occlusion (see Retinal Cases Brief Rep 2014;8;124-126 and Ophthalmology 2020;127;124-126).
They should also not be confused with disc neovascularization, which consists of much smaller caliber vessels that leak on fluorescein angiography.
