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
