Retinal Vascular Occlusion is a condition where blood flow to the retina is blocked, leading to vision problems. This blockage can occur in either the central retinal vein or the retinal arteries, causing symptoms like sudden vision loss or blurred vision. It is often associated with risk factors such as high blood pressure, diabetes, and high cholesterol. Diagnosis typically involves a comprehensive eye examination, including fundoscopy to visualize the retina. Treatment options may include medications, laser therapy, or injections to reduce swelling and improve blood flow. Early detection is crucial to prevent permanent vision loss.
