Uveitis is the inflammation of the uvea, a part of the eye.
Uveitis may come on suddenly with redness and pain, or it may be slow in onset with little pain or redness, but gradual blurring of vision.
Uveitis in the front and middle part of the eye (iritis or cyclitis) is commonly more sudden in onset, generally lasting six to eight weeks, and in the early stages can usually be controlled by the frequent use of drops.

Uveitis is inflammation inside the eye, specifically affecting one or more of the three parts of the eye that make up the uvea: the iris (the colored part of the eye), the ciliary body (behind the iris, responsible for manufacturing the fluid inside the eye), and the choroid (the vascular lining tissue underneath the retina).
Uveitis is the THIRD leading cause of blindness in the United States, after diabetes and macular degeneration.
If the uveitis is on the basis of autoimmunity (the most common form of uveitis), then the uveitis is the manifestation of how your own immune system is inappropriately "attacking" part of your own body.

 Uveitis   (Site not responding. Last check: 2007-11-03)
Uveitis, a term correctly used to describe inflammation of the uveal tract (iris, ciliary body, choroid) alone, actually comprises a large group of diverse diseases affecting not only the uvea but also the retina, optic nerve and vitreous.
The prevalence of uveitis reported in 1984 was 38 per 100,000 in a general population, the annual incidence was 17 per 100,000 with maximum incidence in the 25-44 age group.
In cases of endogenous uveitis in which no link with an infectious agent can be identified, autoimmunity has been invoked as the cause, mainly on the basis of immunopathological findings from eyes removed as a result of the serious sight threatening complications of this group of diseases.

 THE MERCK MANUAL, Sec. 8, Ch. 98, Uveitis
Uveitis is most commonly classified anatomically as anterior, intermediate, posterior, or diffuse.
Anterior uveitis is localized primarily to the anterior segment of the eye and includes iritis and iridocyclitis.
Intermediate uveitis, also called peripheral uveitis, is centered in the area immediately behind the iris and lens in the region of the ciliary body and pars plana, hence the alternate terms "cyclitis" and "pars planitis." Posterior uveitis signifies any of a number of forms of retinitis, choroiditis, or optic neuritis.

 Uveitis
Uveitis is inflammation of the uvea, the middle layer of the eye between the sclera (white outer coat of the eye) and the retina (the back of the eye).
Although the exact cause of uveitis is often unknown, it may result from trauma to the eye, as in the case of chemical exposure.
In addition, uveitis may be caused by a viral infection (for example, cytomegalovirus, as seen in patients with AIDS), a fungal infection (such as histoplasmosis), or an infection caused by a parasite (such as toxoplasmosis; a newborn may develop uveitis if the mother was exposed to toxoplasmosis during pregnancy).

 eMedicine - Iritis and Uveitis : Article by Kilbourn Gordon III, MD   (Site not responding. Last check: 2007-11-03)
Uveitis may involve all areas of the uveal tract; however, involvement most often is (1) anterior, (2) confined to the iris and the anterior chamber (iritis), or (3) confined to the iris, the anterior chamber, and the ciliary body (iridocyclitis).
Uveitis often is associated with infections, such as herpes, toxoplasmosis, and syphilis; therefore, the postulated immune reaction directed against foreign molecules or antigens also may injure the uveal tract vessels and cells.
In uveitis, however, an increase in the protein content of the aqueous causes an effect upon examination known as flare, which is similar to that produced by a moving projector beam in a dark smoky room.
