Tributary (Branch) Retinal Vein Occlusion, Unspecified Eye: Causes, Symptoms, and Treatment

Tributary (branch) retinal vein occlusion is a condition that occurs when there is a blockage in one of the small veins that carry blood away from the retina. This blockage can cause blood to pool in the retina, leading to swelling and vision loss. The condition can affect one or both eyes and can be caused by a variety of factors.


The most common cause of tributary retinal vein occlusion is a blood clot. This clot can form in the small veins that drain blood from the retina or in larger vessels that supply blood to these smaller veins. Other causes of the condition include:

  1. Diabetes
  2. High blood pressure
  3. Glaucoma
  4. Macular edema
  5. Retinal detachment
  6. Atherosclerosis

The symptoms of tributary retinal vein occlusion can vary depending on the severity of the condition. Some common symptoms include:

  • Blurred or distorted vision
  • Loss of peripheral vision
  • Floaters or spots in your vision
  • Difficulty seeing in low light conditions
  • Sensitivity to light

If you experience any of these symptoms, it is important to see an eye doctor immediately. Early treatment can help prevent further vision loss.


The treatment for tributary retinal vein occlusion depends on the cause of the condition. In some cases, the blockage will clear up on its own within a few weeks or months. However, if the blockage persists, your doctor may recommend one or more of the following treatments:

  1. Injections of anti-VEGF medications to reduce swelling and improve blood flow
  2. Laser photocoagulation to seal leaking blood vessels and reduce swelling
  3. Vitrectomy surgery to remove blood and scar tissue from the eye
  4. Corticosteroid injections to reduce inflammation and swelling
  5. Aspirin therapy to help prevent blood clots

If you have been diagnosed with tributary retinal vein occlusion, it is important to follow your doctor's treatment plan closely. With proper treatment, many people are able to regain some or all of their vision.
