Uveitis is an infection of the eye that is often painful. If you are unsure about an eye problem, it is best to talk to a health professional. If you have sudden pain in your eye, see a doctor as soon as possible.
What is uveitis?
Uveitis is an inflammation of the middle layer of the wall of your eye. The uvea, which becomes inflamed, sits under the sclera, which is the white outer layer.
You can get different types of uveitis, such as:
- anterior uveitis, which affects the iris in the front of the eye
- intermediate uveitis, which affects between the iris and the lens
- posterior uveitis, which affects the retina and blood vessels at the back of your eye
- panuveitis, which involves all parts of the middle layer.
What causes uveitis?
Uveitis can be caused by:
But often, the cause isn’t clear.
Uveitis usually causes a red painful eye. The light hurts your eyes. You might get blurred vision and seeing dark floating spots. It can come on suddenly or slowly, and it can affect one or both eyes.
If you are worried about your eyes, see your doctor or optometrist. Many eye conditions go away on their own, but if you have uveitis and it is left untreated, it can result in loss of vision.
Your doctor or optometrist will do a full eye examination. If they suspect uveitis, you might also need:
- blood tests
- testing the fluid of the eye
- photography of the blood flow of the eye
- photography of the retina.
Treatment aims to reduce inflammation and resolve any underlying condition, such as infection. Medication might include:
- corticosteroid eyedrops, pills or injection
- antibiotics or antivirals
- other medications known as immune system modifiers.
Some people with uveitis need surgery to remove some fluid or to implant a medicated device into the eye.
