Retinal Disease

What is Retinal Vein Occlusion?

Retinal vein occlusion is a blockage in the veins in the eye which can lead to blurring, fuzziness or changes to vision. This blockage leads to a build up of fluid causing swelling in the area of the retina (the light-sensitive layer at the back of the eye). The swelling may lead to damage to the macular which affects central vision, used for tasks such as reading.

What is non-infectious uveitis?

Non-infectious uveitis occurs when the uvea in the eye becomes inflamed. The uvea is the middle layer of your eye and a healthy uvea is essential for normal vision. Non-infectious uveitis means there is no infection (caused by bacteria or viruses) in your eye.

Why do people get non-infectious uveitis?

Non-infectious uveitis can happen in people who have a condition affecting their immune system, such as multiple sclerosis or inflammatory bowel disease. However, in around half of cases, doctors don’t know why non-infectious uveitis has happened because it occurs spontaneously or from an unknown cause.
