Understanding Retinal Vein Occlusion: Causes Symptoms and Treatment Options
Your eyes work hard every single day, but sometimes things can go wrong deep inside where you can’t see it happening. One of those issues is called retinal vein occlusion. It sounds complicated, but it basically means there’s a blockage in one of the veins that carries blood away from your retina—the part of your eye responsible for sharp, detailed vision.
When that blockage happens, it can cause sudden blurry vision or even vision loss. You might not feel any pain, but the changes in your sight can be hard to ignore. In this article, we’ll explain the different types of retinal vein occlusion, what causes it, and how treatment can help.
What is Retinal Vein Occlusion?
The Symptoms of Retinal Vein Occlusion Can Include:
- Blurry vision that appears suddenly or slowly worsens
- Dark spots or floaters drifting across your sight
- Loss of part or all of your field of vision
- Sudden vision loss without any pain
- Distorted central vision that affects daily activities
- Swelling or pressure around the eye area
What Causes Retinal Vein Occlusion?
Several risk factors can increase your chances of developing this condition. High blood pressure, diabetes, glaucoma, and smoking all damage blood vessels over time. A blood clot can also trigger the blockage, restricting blood flow in the affected area.
When the blockage happens, abnormal blood vessels sometimes grow in the retina to make up for the loss. Unfortunately, these fragile vessels can leak, leading to more damage. In severe cases, macular edema—swelling in the center of the retina—develops, causing further vision loss.
Treatment Options for Retinal Vein Occlusion
Treatments focus on protecting your sight and managing complications like macular edema, which can lead to vision loss if left untreated. One of the most common approaches is eye injections that target vascular endothelial growth factor. These injections help stop abnormal new blood vessels from growing and reduce swelling inside the eye.
In some cases, your doctor might recommend laser therapy to seal off leaking blood vessels and prevent further damage. If you’re dealing with retinal vein occlusion CRVO or branch retinal vein occlusion, medications might also be used to lower eye pressure, dissolve a blood clot, and improve blood flow to the retina.
Managing underlying conditions like high blood pressure or diabetes is just as important. Catching it early and following a personalized treatment plan can protect your vision and prevent long-term complications. Don’t wait—always get your eyes checked if anything doesn’t feel right.
