Background: Prepapillary vascular loops are a type of congenital vascular anomaly seen on or around the optic disk. Patients with
this condition are usually asymptomatic and are detected incidentally on routine fundus examinations. Differential diagnosis for this
condition includes neovascularization of the disk and collaterals on the disk. Prepapillary capillary loops are not associated with any
systemic condition. They are usually unilateral in presentation, but can rarely be bilateral. Purpose: To discuss the new proposed
classification of prepapillary capillary loops. Synopsis: Prepapillary capillary loops are classified based on their location around the
disk, loop characteristics such as elevation, shape, and covering, and presence of vitreoretinal traction. Highlights: The most common
vascular loops are arterial in origin and rarely venous in origin. They can sometimes be associated with spontaneous and recurrent
vitreous hemorrhage, branch retinal artery or vein occlusion, and subretinal hemorrhage. It is an important differential diagnosis in
spontaneous vitreous hemorrhage. Treatment is symptomatic
