Uveitis is a form of eye inflammation. It affects the middle layer of tissue in the eye wall (uvea).
Uveitis (u-vee-I-tis) warning signs often come on suddenly and get worse quickly. They include eye redness, pain and blurred vision. The condition can affect one or both eyes. It primarily affects people ages 20 to 50, but it may also affect children.
Possible causes of uveitis are infection, injury, or an autoimmune or inflammatory disease. Many times a cause can’t be identified.
Uveitis can be serious, leading to permanent vision loss. Early diagnosis and treatment are important to prevent the complications of uveitis.
Eye with uvea
The signs, symptoms and characteristics of uveitis include:
- Eye redness
- Eye pain
- Light sensitivity
- Blurred vision
- Dark, floating spots in your field of vision (floaters)
- Decreased vision
Symptoms may occur suddenly and get worse quickly, though in some cases, they develop gradually. They may affect one or both eyes.
The uvea is the middle layer of tissue in the wall of the eye. It consists of the iris, the ciliary body and the choroid. The choroid is sandwiched between the retina and the sclera. The retina is located at the inside wall of the eye and the sclera is the outer white part of the eye wall. The uvea provides blood flow to the deep layers of the retina. The type of uveitis you have depends on which part or parts of the eye are inflamed:
- Iritis (anterior uveitis) affects the front of your eye and is the most common type.
- Cyclitis (intermediate uveitis) affects the ciliary body.
- Choroiditis and retinitis (posterior uveitis) affect the back of your eye.
- Diffuse uveitis (panuveitis) occurs when all layers of the uvea are inflamed.
In any of these conditions, the jelly-like material in the center of your eye (vitreous) can become inflamed and infiltrated with inflammatory cells.
When to seek medical advice
Contact your doctor if you think you have the warning signs of uveitis. He or she may refer you to an eye specialist (ophthalmologist). If you’re having significant eye pain and unexpected vision problems, seek immediate medical attention.

Useful info and health tips
What is uveitis?
Uveitis is swelling of the middle layer of the eye, which is called the uvea. It may occur from both infectious and non-infectious causes. The uvea supplies blood to the retina. The retina is the light-sensitive part of the eye that focuses the images you see and sends them to the brain. It’s normally red due to its blood supply from the uvea.
Uveitis usually isn’t serious. More severe cases can cause vision loss if not treated early.
