Cilioretinal Artery Imaged with Optical Coherence Tomography Angiography

A 48-year-old woman presented with peripapillary chorioretinal atrophy and cilioretinal artery in the left eye without other findings (Fig 1A). Optical coherence tomography angiography (OCTA) through full-thickness retinal segmentation (Fig 1B) showed intact retinal perfusion. The cilioretinal artery arose from the temporal margin of the optic nerve and coursed into the retina, resembling a hook. On OCT B-scan with angio-overlay (Fig 1C), the cilioretinal artery was visualized at 2 levels, with the point of the hook (arrow) at the level of the retinal pigment epithelium and the shank of the hook (arrowhead) at the level of the nerve fiber layer (Magnified version of Fig 1A-C available online at www.aaojournal.org).
