Central retinal artery occlusion; Branch retinal artery occlusion; CRAO; BRAO

Measures used to prevent other blood vessel (vascular) diseases, such as coronary artery disease, may decrease the risk of retinal artery occlusion. These include:

• Eating a low-fat diet
• Exercising
• Stopping smoking
• Losing weight if you are overweight

Sometimes blood thinners may be used to prevent the artery from becoming blocked again. Aspirin or other anti-clotting drugs are used if the problem is in the carotid arteries. Warfarin or other more potent blood thinners are used if the problem is in the heart.
