Major Branch Retinal Vein Occlusion (BRVO) is a medical condition that affects the blood vessels in the eye, specifically the veins that carry blood away from the retina. When one of these veins becomes blocked, it can lead to various problems with vision and can even cause permanent damage if not treated promptly. In this article, we will provide simplified explanations for different aspects of BRVO, including its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgery options.
Types of Major Branch Retinal Vein Occlusion
- Branch Retinal Vein Occlusion (BRVO): This condition occurs when a small branch of the main retinal vein gets blocked.
Causes of Major Branch Retinal Vein Occlusion
- Age: As we get older, the risk of developing BRVO increases.

Diagnostic Tests for Major Branch Retinal Vein Occlusion
- Ophthalmoscopy: An eye doctor examines the retina using a special instrument with a bright light.
- Fluorescein Angiography: A dye is injected into a vein, and photographs are taken to assess blood flow.
- Optical Coherence Tomography (OCT): High-resolution images of the retina are created to detect swelling and damage.
- Visual Acuity Test: Measures how well you can see at various distances.
- Tonometry: Measures eye pressure, which can help diagnose glaucoma.
- Blood Tests: Assess cholesterol, blood sugar, and other factors that may contribute to BRVO.
- Dilated Eye Exam: Pupil-dilating drops allow a thorough examination of the retina.
- Visual Field Test: Determines if there are any blind spots in your field of vision.
- Ultrasound: Uses sound waves to create images of the eye’s interior.
- Electroretinography (ERG): Measures the electrical activity of the retina.
- Intraocular Pressure Measurement: Measures the pressure inside the eye.
- Color Vision Testing: Checks for color perception abnormalities.
- Contrast Sensitivity Test: Assesses your ability to detect subtle differences in shades.
- Amsler Grid: A grid pattern helps detect distorted or missing areas in your vision.
- Retinal Photography: Detailed photos of the retina for monitoring changes over time.
- B-scan Ultrasonography: Provides cross-sectional images of the eye.
- Visual Evoked Potentials (VEP): Measures the time it takes for visual signals to reach the brain.
- Blood Coagulation Tests: Checks for abnormal clotting factors.
- Erythrocyte Sedimentation Rate (ESR): Evaluates inflammation levels.
- Genetic Testing: Identifies genetic factors that may contribute to BRVO.
Treatments for Major Branch Retinal Vein Occlusion
