What is uveitis?
Uveitis is swelling and irritation of the uvea, the middle layer of the eye. The uvea[ provides most of the blood supply to the retina.
What are the symptoms of uveitis?
Uveitis can affect one or both eyes. Symptoms may develop rapidly and can include:
- Blurred vision
- Dark, floating spots in the vision
- Eye pain
- Redness of the eye
- Sensitivity to light
What are the causes of uveitis?
Uveitis can be caused by autoimmune disorders such as rheumatoid arthritis or ankylosing spondylitis, infection, or exposure to toxins. However, in many cases the cause is unknown.
The most common form of uveitis is anterior uveitis, which involves inflammation in the front part of the eye. It is often called iritis because it is usually only effects the iris, the colored part of the eye. The inflammation may be associated with autoimmune diseases, but most cases occur in healthy people. The disorder may affect only one eye. It is most common in young and middle-aged people.
Posterior uveitis affects the back part of the uvea, and involves primarily the choroid, a layer of blood vessels and connective tissue in the middle part of the eye. This type of uveitis is called choroiditis. If the retina is also involved it is called chorioretinitis. You may develop this condition if you have had a body-wide (systemic) infection or if you have an autoimmune disease.
Another form of uveitis is pars planitis. This inflammation affects the narrow area between the colored part of the eye (iris) and the choroid. Pars planitis usually occurs in young men and is generally not associated with any other disease. However, some evidence suggests it may be linked to Crohn's disease and possibly multiple sclerosis.
Uveitis can be associated with any of the following:
- AIDS
- Ankylosing spondylitis
- Behcet syndrome
- CMV retinitis
- Herpes zoster infection
- Histoplasmosis
- Injury
- Kawasaki disease
- Psoriasis
- Reactive arthritis
- Rheumatoid arthritis
- Sarcoidosis
- Syphilis
- Toxoplasmosis
- Tuberculosis
- Ulcerative colitis
Who is at risk for uveitis?
How to know you have uveitis?
A complete medical history and eye examination should be performed. Laboratory tests may be done to rule out infection or an autoimmune disorder.
Persons over age 25 with pars planitis should have an MRI of their brain and spine to rule out multiple sclerosis.
