Aspirin may be given to thin the blood, thus encouraging circulation. In almost all cases, only one eye is affected. Of the 33 patients, 16 48.5% had central retinal vein occlusion, 9 27.3% had branched retinal vein occlusion, 4 12.1% had hemiretinal vein occlusion, and 1 each 3.0% had central retinal arterial occlusion, branch retinal arterial occlusion, and combined hemiretinal vein occlusion and branch retinal artery occlusion.
