Uveitis is inflammation of any part of the uvea, which comprises the iris (the colored part of the eye), ciliary body (a ring of muscle behind the iris), and choroid (the tissue layer that supports the retina). In many cases, uveitis is thought to be due to an autoimmune disorder (in which the immune system attacks the body’s own tissues), such as Crohn’s disease or ankylosing spondylitis, or an infection, such as chicken pox , shingles , or tuberculosis. In some cases, there is no obvious cause.
Symptoms may include redness and soreness of the eye, blurred vision, small or irregularly shaped pupils, and sensitivity to bright light.
Treatment with corticosteroids is usually effective. In some cases, eye drops to relax muscles in the eye may also be given.
Without prompt treatment, there is a risk of permanent visual impairment
