A retinal vein occlusion is a blockage of the small veins that carry blood away from the retina. It results in dramatic hemorrhages (as seen in this patients right eye above) , retinal swelling and profound vision loss.

Prevention involves eating a low-fat diet, regular exercise, maintaining an ideal weight, not smoking and controlling diabeties.
