This Ophthalmic Image shows a prepapillary vascular loop in a teenage boy.

A teenage boy with a history of branch retinal artery occlusion secondary to traumatic torsion of a prepapillary vascular loop1 was re-examined 2 years later. Visual acuity was 20/20 OD with a relative superior visual field defect on Humphrey perimetry. Optical coherence tomography angiography was performed. Foveal perfusion was intact, without absence of flow surrounding the foveal avascular zone. Imaging of the superficial capillary plexus revealed absence of capillary flow and reduced visualization of vessels in the inferior macula consistent with prior artery occlusion (Figure). No recurrent artery occlusion occurred in the follow-up period.

Imaging of a prepapillary vascular loop. Fundus photography (A) and optical coherence tomography angiography (B) highlight a prepapillary vascular loop (yellow arrowheads). Optical coherence tomography angiography revealed absence of capillary flow in the superficial capillary plexus (white arrowheads) consistent with prior arterial occlusion. Foveal perfusion was preserved.
