Vein | Vascular Occlusion of the eye

Vein or vascular occlusion can occur in the eye, affecting the veins or arteries that supply blood to the retina, the part of the eye responsible for vision.

When a vein in the eye becomes occluded, it can result in a condition called central retinal vein occlusion (CRVO), which is a blockage of the central retinal vein that can lead to vision loss. CRVO can occur due to a blood clot or other obstructions that prevent blood from flowing out of the retina. Risk factors for CRVO include high blood pressure, diabetes, glaucoma, and a history of blood clots.

Similarly, occlusion of the arteries in the eye can cause a condition called central retinal artery occlusion (CRAO), which is a blockage of the central retinal artery that can result in sudden, painless vision loss. CRAO can occur due to an embolus, a piece of material that blocks the artery and prevents blood flow to the retina. Risk factors for CRAO include high blood pressure, high cholesterol, heart disease, and smoking.

Treatment for vein or vascular occlusion of the eye may depend on the underlying cause and severity of the blockage. In some cases, treatment may involve medications to reduce swelling and prevent further blood clots, while in other cases, laser therapy or surgical procedures may be necessary to restore blood flow and prevent vision loss. Early diagnosis and treatment are essential to prevent permanent damage to the retina and preserve vision.
