Case 5-13. Acute Central Retinal Artery Obstruction

Clinical Summary

An 85-year-old man experienced a sudden loss of vision in his right eye five days earlier. Fundus examination (A) showed a cherry-red spot in the fovea with pate and edematous tissue throughout the macula. The retinal arterioles and venules were markedly attenuated.

Optical Coherence Tomography

A horizontal OCT image (B) through the fovea displayed diffuse thickening of the neurosensory retina, increased reflectivity was noted from the inner retinal layers corresponding to retinal ischemia, and decreased back-scattering was observed from the retinal photoreceptors due to fluid accumulation and retinal edema.
