A case of cilioretinal artery occlusion resembling hemicentral retinal artery occlusion

摘要

A 77-year-old man presented with an inferior hemivisual field defect in the left eye. Funduscopy revealed well demarcated retinal edema of the superior quadrant resembling hemicentral retinal artery occlusion. Further, the upper and inferior retinal arteries emerged separately from the optic disc. Fluorescein angiography demonstrated a marked filling delay of the upper retinal artery. We repeated fluorescein angiography, which showed that the involved upper retinal artery was a cilioretinal artery having an earlier dye appearance than the lower retinal artery. We suggest that when cases of hemicentral retinal artery occlusion are encountered, vascular architecture at the optic disc should be evaluated carefully.
