Branch Retinal Vein Occlusion (BRVO) occurs when one of the small veins in the retina becomes blocked. This blockage can lead to fluid leakage and bleeding in the retina, causing vision problems. Symptoms may include blurred or distorted vision in one eye, and it often affects older adults or those with underlying health conditions like diabetes or high blood pressure. Diagnosis typically involves a comprehensive eye exam, including fundoscopy to examine the retina. Treatment options may include laser therapy, injections of medications to reduce swelling, or managing underlying health issues. Early detection and intervention are crucial to preserving vision.
