OPTICAL COHERENCE TOMOGRAPHY FINDINGS IN CENTRAL RETINAL ARTERY OCCLUSION

摘要

Central retinal artery occlusion is a potentially devastating visual disorder usually caused by closure of the vessel by atheroma or emboli. Sustained blockage of blood flow to the eye may lead to irreversible blindness and secondary ocular complications. In central retinal artery occlusion, the retina appears white as a result of cloudy swelling caused by intracellular edema, especially at the posterior pole where the nerve fiber and ganglion cell layers are thickest. Because the central fovea is devoid of these layers, the orange reflex from the intact choroidal vessels beneath the foveola stands out in contrast to the surrounding opaque retina, giving rise to the "cherry-red spot" appearance. We describe optical coherence tomography (OCT) findings for a 65-year-old man with acute central retinal artery occlusion.
