Superior Branch Retinal Artery Occlusion (S-BRAO)

Superior Branch Retinal Artery Occlusion (S-BRAO) is a medical condition that affects the eye, specifically the retina. It occurs when a blood vessel that supplies the retina with oxygen and nutrients becomes blocked. In this article, we’ll break down S-BRAO into simple terms, explaining its types, causes, symptoms, diagnostic tests, treatment options, and relevant medications.

Types of Superior Branch Retinal Artery Occlusion:

1. Complete S-BRAO: This is when the entire branch artery becomes blocked, leading to a more severe vision loss.
2. Partial S-BRAO: In this case, only a part of the branch artery is blocked, resulting in a partial loss of vision.

Causes of Superior Branch Retinal Artery Occlusion:

1. Atherosclerosis: A buildup of fatty deposits in the arteries can restrict blood flow to the retina.
2. Embolism: A small clot or debris can travel to the retinal artery and block it.
3. Hypertension (High Blood Pressure): High blood pressure can damage the blood vessels in the eye, increasing the risk of S-BRAO.
4. Diabetes: Poorly managed diabetes can lead to changes in the blood vessels, making them more prone to blockages.
5. Cardiovascular Diseases: Conditions like heart disease can increase the risk of embolisms.
6. Glaucoma: Elevated eye pressure can reduce blood flow to the retina.
7. Vasculitis: Inflammation of blood vessels can lead to blockages.
8. Blood Disorders: Certain blood disorders can make clots more likely to form.
9. Medications: Some drugs can increase the risk of blood clots.
10. Trauma: An injury to the eye can damage blood vessels and cause blockages.
11. Genetic Factors: In rare cases, genetic factors may contribute to S-BRAO.
12. Smoking: Smoking is a risk factor for many vascular diseases, including those that can lead to S-BRAO.
13. High Cholesterol: Elevated cholesterol levels can contribute to atherosclerosis.
14. Age: The risk of S-BRAO increases with age.
15. Obesity: Being overweight can increase the risk of hypertension and diabetes.
16. Oral Contraceptives: Some birth control pills can increase the risk of blood clots.
17. Migraine with Aura: This type of migraine may increase the risk of S-BRAO.
18. Autoimmune Diseases: Certain autoimmune conditions can affect blood vessels.
19. Radiation Therapy: In rare cases, radiation therapy near the eye can cause damage to blood vessels.
20. Alcohol and Drug Abuse: Substance abuse can lead to various health problems, including those affecting blood vessels.

Symptoms of Superior Branch Retinal Artery Occlusion:

1. Sudden Vision Loss: The most common symptom is a sudden and painless loss of vision in one eye.
2. Blurred Vision: Objects may appear blurry or distorted.
3. Field of Vision Loss: You may experience a blind spot or dark area in your visual field.
4. Decreased Color Perception: Colors may appear less vibrant.
5. Floaters: Tiny specks or spots may float across your field of vision.
6. Eye Pain: Some individuals may experience mild eye discomfort.
7. Headache: In some cases, a headache may accompany S-BRAO.
8. Halos: You may see halos around lights.
9. Eye Redness: The affected eye may appear red or bloodshot.
10. Difficulty Reading: Reading may become challenging due to the loss of central vision.
11. Loss of Contrast Sensitivity: It may be harder to distinguish between shades of gray.
12. Distorted Vision: Straight lines may appear wavy or crooked.
13. Photophobia: Increased sensitivity to light can occur.
14. Double Vision: Some individuals may experience double vision in the affected eye.
15. Nausea and Vomiting: This is rare but can happen in severe cases.
16. Eye Swelling: The eye may become swollen or appear bulging.
17. Tearing: Excessive tearing can occur.
18. Eyelid Drooping: The eyelid on the affected side may droop slightly.
19. Difficulty with Depth Perception: Judging distances may become more challenging.
20. Vision Improvement: In some cases, vision may spontaneously improve over time.

Diagnostic Tests for Superior Branch Retinal Artery Occlusion:

1. Ophthalmoscopy: An eye doctor examines the retina using a special instrument to look for blockages and changes in blood vessels.
2. Fluorescein Angiography: A dye is injected into a vein, and photographs are taken to identify blood flow problems in the retina.
3. Optical Coherence Tomography (OCT): This imaging test provides detailed cross-sectional images of the retina.
4. Visual Field Test: This assesses the extent of your visual field loss.
5. Blood Pressure Measurement: High blood pressure can contribute to S-BRAO, so your blood pressure will be checked.
6. Blood Tests: These can identify underlying conditions like diabetes or high cholesterol.
7. Echocardiogram: This ultrasound of the heart can help identify potential sources of emboli.
8. Carotid Ultrasound: This test checks for blockages in the carotid arteries, which can contribute to embolism.
9. Doppler Ultrasound: It measures blood flow in the eye and can identify blockages.
10. Magnetic Resonance Imaging (MRI): In some cases, an MRI of the brain and eye may be performed.
11. Electroretinogram (ERG): This test measures the electrical activity of the retina.
12. Complete Blood Count (CBC): It can reveal abnormalities in blood cells that may indicate underlying conditions.
13. Erythrocyte Sedimentation Rate (ESR): Elevated ESR can suggest inflammation in the blood vessels.
14. C-reactive Protein (CRP) Test: High CRP levels can indicate inflammation.
15. Lipid Profile: This measures cholesterol levels in the blood.
16. Coagulation Profile: It assesses the blood’s clotting ability.
17. Holter Monitor: A portable device records your heart’s electrical activity over a period.
18. Transesophageal Echocardiogram (TEE): This specialized echocardiogram provides detailed images of the heart’s structures.
19. Carotid Angiography: A contrast dye is injected into the carotid artery, and X-rays are taken to check for blockages.
20. Chest X-ray: This can reveal any issues with the heart and lungs.

Conclusion

Superior Branch Retinal Artery Occlusion (SBRARO) might be a mouthful, but understanding it doesn’t have to be complicated. It’s a condition where the upper part of your eye’s “film” loses its blood supply, causing vision problems. There are different types, causes, symptoms, diagnostic tests, treatments, drugs, and even surgery options to consider.

Remember, if you experience any symptoms or suspect you have SBRARO, it’s crucial to see an eye specialist promptly. Early diagnosis and appropriate treatment can make a significant difference in preserving your vision and overall eye health.
