Historically, uveitis is a term used to describe inflammatory processes of the portion of the eye known as the uvea, which is composed of the iris, ciliary body, and the choroid; however, any area of the eye can be inflammed. Uveitis can be further subdivided into anterior, intermediate, posterior, and panuveitis based on the primary anatomical location of the inflammation in the eye.
