Macular Branch Retinal Artery Occlusion (BRAO)

Macular Branch Retinal Artery Occlusion (BRAO) is a medical condition that affects the eye, specifically the retina. In this article, we will break down what BRAO is, its different types, potential causes, common symptoms, how it is diagnosed, various treatment options available, and medications or surgeries that may be prescribed to manage the condition.

Macular Branch Retinal Artery Occlusion, or BRAO, occurs when a small blood vessel in the retina gets blocked. The retina is like the camera film at the back of your eye, responsible for capturing images and sending them to your brain.

BRAO can affect a specific area of the retina known as the macula, which is essential for sharp and detailed vision. When this area doesn’t get enough blood supply due to the blockage, it can lead to vision problems.

Types of BRAO

There are different types of BRAO, depending on the location of the blocked blood vessel. The two main types are:

1. Central BRAO: When the central artery, which supplies blood to the macula, gets blocked. This can cause severe vision loss in the central part of your field of vision.
2. Branch BRAO: This occurs when a smaller branch of the central artery gets blocked. It affects a smaller area of the retina and typically causes less severe vision loss.

Causes of BRAO

Various factors can lead to BRAO. Here are 20 common causes:

1. Atherosclerosis: Narrowing and hardening of the arteries due to plaque buildup.
2. High Blood Pressure: Increased blood pressure can damage blood vessels.
3. Blood Clots: Clots can block the retinal artery.
4. Diabetes: Uncontrolled diabetes can harm blood vessels.
5. Smoking: Smoking increases the risk of artery damage.
6. High Cholesterol: Elevated cholesterol levels can contribute to plaque formation.
7. Glaucoma: Increased eye pressure may affect blood flow.
8. Inflammation: Conditions like vasculitis can cause artery inflammation.
9. Cardiovascular Disease: Heart issues can lead to BRAO.
10. Blood Disorders: Conditions like sickle cell anemia can affect blood flow.
11. Medications: Certain drugs may increase the risk of BRAO.
12. Migraines: Some types of migraines can trigger BRAO.
13. Hypercoagulability: Blood clotting disorders can be a cause.
14. Age: Risk increases with age.
15. Family History: Genetics may play a role.
16. Gender: Men may be more prone to BRAO.
17. Obesity: Excess weight can contribute to vascular problems.
18. Sleep Apnea: Breathing problems during sleep may affect blood vessels.
19. Radiation Exposure: Certain treatments may increase risk.
20. Eye Trauma: Injuries can damage blood vessels in the eye.
