Ischemic Ocular Syndrome - Color Fundus Photographs

These are color fundus photographs of a 61 year old man with reduced visual acuity to counting fingers in the left eye. He had hypertension, diabetes mellitus, and hypercholesterolemia, and previously had undergone coronary artery bypass grafting for coronary artery disease. Visual acuity in the right eye was 20/20. Note the deep retinal hemorrhages (white arrows) where retinal blood vessels traverse superficially. The veins of the affected left eye are dilated compared to the unaffected right eye. Note the absence of optic disc edema, an important distinguishing characteristic of this condition as compared to central retinal vein occlusion.
