Retinal Vein Occlusions (RVO)
Comprehensive Management for RVO and Macular Swelling
Superotemporal BRVO: The image shows a blocked vein in the upper-outer retina with leakage (exudates) affecting the central vision.
At a Glance
- The Condition: A blockage in the veins that carry blood away from the retina.
- Primary Symptom: Sudden, painless blurring or vision loss, typically in only one eye.
- Common Causes: Often linked to high blood pressure, diabetes, or cardiovascular disease.
What is Retinal Vein Occlusion?
Retinal vein occlusion occurs when one of the veins that carries blood away from the retina becomes blocked. This blockage causes blood and fluid to leak into the retina, often leading to sudden, painless blurring or vision loss in one eye. This leakage can cause the macula to swell (macular edema), which is the primary cause of vision loss in RVO patients.
Types of Vein Occlusion
- Branch Retinal Vein Occlusion (BRVO): A blockage in one of the smaller “branches” of the retinal veins.
- Central Retinal Vein Occlusion (CRVO): A blockage in the main vein of the retina, often leading to more widespread vision changes.
Is your vision distorted or wavy?
Patients with macular edema from a vein occlusion often notice that straight lines appear bent or fuzzy. You can use an Amsler Grid at home to monitor for these changes.
Protect Your Vision from RVO Damage
Managing macular swelling is essential to recovering sight after a vein occlusion. Dr. Elshatory specializes in the latest treatments to reduce edema and preserve your sight.
