Uveitis
Iritis; Pars planitis; Choroiditis; Chorioretinitis; Anterior uveitis; Posterior uveitis; Iridocyclitis
Uveitis is swelling and irritation of the uvea . The uvea is the middle layer of the eye. The uvea provides most of the blood supply to the retina .

Causes
Uveitis can be caused by autoimmune disorders . These diseases occur when the body's immune system attacks and destroys healthy body tissue by mistake. Examples are:

Tuberculosis
Tuberculosis
Pulmonary tuberculosis (TB) is a contagious bacterial infection that involves the lungs. It may spread to other organs.
Exposure to toxins or injury can also cause uveitis. In many cases, the cause is unknown.
The most common form of uveitis involves inflammation the front part of the eye. It is often called iritis because it most often only affects the iris. The iris is the colored part of the eye. In most cases, it occurs 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 eye. It involves primarily the choroid . This is the layer of blood vessels and connective tissue in the middle layer of the eye. This type of uveitis is called choroiditis. If the retina is also involved, it is called chorioretinitis.
Choroid
The choroid is the layer of blood vessels and connective tissue between the white of the eye and retina (at the back of the eye). It is part of the ...
Another form of uveitis is pars planitis. Changes involve the narrowed area (pars plana) between the colored part of the eye (iris) and the choroid. Pars planitis most often occurs in young men. It is generally not associated with any other disease. However, it may be linked to Crohn disease and possibly multiple sclerosis.
Symptoms
Uveitis can affect one or both eyes. Symptoms may develop rapidly and can include:
-
Blurred vision
Blurred vision
There are many types of eye problems and vision disturbances, such as: HalosBlurred vision (the loss of sharpness of vision and the inability to see ...
- Dark, floating spots in the vision
-
Eye pain
Eye pain
Pain in the eye may be described as a burning, throbbing, aching, or stabbing sensation in or around the eye. It may also feel like you have a forei...
-
Redness of the eye
Redness of the eye
Eye redness is most often due to swollen or dilated blood vessels. This makes the surface of the eye look red or bloodshot.
-
Sensitivity to light
Sensitivity to light
Photophobia is eye discomfort in bright light.
Exams and Tests
The health care provider will take a complete medical history and do an eye exam. Lab tests may be done to rule out infection or a weak immune system.
If you are over age 25 and have pars planitis, your provider will suggest a brain and spine MRI. This will rule out multiple sclerosis.
Treatment
Iritis (anterior uveitis) is most often mild. Treatment may involve:
- Dark glasses
- Eye drops that dilate the pupil to relieve pain
- Steroid eye drops
Pars planitis is often treated with steroid eye drops. Other medicines, including steroids taken by mouth, may be used to help suppress the immune system.
Posterior uveitis treatment depends on the underlying cause. It almost always includes steroids taken by mouth.
If the uveitis is caused by a body-wide (systemic) infection, you may be given antibiotics. You may also be given powerful anti-inflammatory medicines called corticosteroids.
Outlook (Prognosis)
With proper treatment, most attacks of anterior uveitis go away in a few days to weeks. However, the problem often returns.
Posterior uveitis may last from months to years. It may cause permanent vision damage, even with treatment.
Possible Complications
Complications may include:
- Cataracts
- Fluid within the retina
-
Glaucoma

When to Contact a Medical Professional
Symptoms that need urgent medical care are:
- Eye pain
- Reduced vision
Prevention
If you have a body-wide (systemic) infection or disease, treating the condition will prevent uveitis.

Eye - illustration
The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle tunic layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.
