Abstract: Uveitis is a general term describing a group of inflammatory diseases that produces swelling anddestroys eye tissues. These diseases can slightly reduce vision or lead to severe vision loss.The uvea is the middle layer of the eye. It lies beneath the white part of the eye (the sclera). It ismade of the iris, ciliary body, and choroid. These structures control many eye functions,including adjusting to different levels of light or distances of objects. The term “uveitis” is used because the diseases often affect a part of the eye called the uvea.Nevertheless, uveitis is not limited to the uvea. These diseases also affect the lens, retina, opticnerve, and vitreous, producing reduced vision or blindness.It is characterized as seen in young adults with both eyes affected to it, mostly recurrent and cancause blindness.Uveitis may be caused by problems or diseases occurring in the eye or it can be part of aninflammatory disease affecting other parts of the body.It can happen at all ages and primarily affects people between 20-60 years old.Uveitis can last for a short (acute) or a long (chronic) time. The severest forms of uveitis reoccurmany times.
