What is Uveitis?
Uveitis is an inflammation that occurs in the middle layer of the eye. It can also lead to inflammation in the adjacent areas, like the retina and fluid in the back of the eye (called vitreous).
Importance of Uveitis
When any part of the uvea becomes inflamed, the condition is labeled as uveitis. This may be further subdivided depending upon the exact structures involved in the inflammation. Thus, if only the iris is inflamed it is called Iritis. Similarly Cyclitis is inflammation of the ciliary body. Anterior uveitis or iridocyclitis is inflammation of both the iris and ciliary body. Choroiditis or posterior uveitis is inflammation of the choroid. Intermediate uveitis is inflammation of the middle part of the uvea and is commonly also referred to as pars planitis. If all structures (iris, ciliary body and choroid) are inflamed then it is called panuveitis. These are medical terms but are helpful for you to know.
