Retinal Vein Occlusion
What is Retinal Vein Occlusion?
Retinal vein occlusion is a blockage of one or more veins in the retina, the light-sensitive tissue at the back of the eye responsible for sending visual signals to the brain.
There are two main types of RVO: Branch retinal vein occlusion (BRVO) occurs when a branch of the main retinal vein is blocked, affecting only a portion of the retina.
Central retinal vein occlusion occurs when the main retinal vein is blocked, affecting the entire retina.
RVO can cause sudden, painless vision loss or blurring in the affected eye. Without prompt treatment, it can lead to serious complications, including permanent vision loss.

Symptoms of Retinal Vein Occlusion
The symptoms of retinal vein occlusion may include:
- Sudden, painless loss of vision or blurring in one eye
- Gradual vision loss over a few days or weeks
- Dark or blind spots in your field of vision
- Floaters (small specks or cobweb-like shapes that appear to float in your vision)
- Pain or pressure in the affected eye (less common)
If you experience any sudden changes in your vision, it’s crucial to schedule an appointment with the knowledgeable team at The Sight Centre.

What are the Causes of Retinal Vein Occlusion?
Retinal vein occlusion (RVO) occurs when a blood clot blocks a vein in the retina, causing blood and fluid to leak into the surrounding tissue. Several factors can increase the risk of developing RVO.
Age is a significant risk factor, as RVO is more common in people over 50. Hypertension, or high blood pressure, can damage blood vessels in the retina, increasing the risk of RVO.
Diabetes is another risk factor, as it can cause damage to the blood vessels in the retina, making them more susceptible to blockage. High cholesterol levels can contribute to the formation of blood clots and increase the risk of RVO.
People with glaucoma, an eye condition that damages the optic nerve, have an increased risk of developing RVO. Certain blood disorders that increase the risk of clotting can also increase the likelihood of RVO.
