Disease: Uveitis
Symptoms: Eye with uvea The uvea consists of structures of the eye beneath the white of the eye (sclera). It has three parts: (1) the iris, which is the colored part of the eye; (2) the ciliary body, which is the structure in the eye that secretes the transparent liquid within the front of the eye; and (3) the choroid, which is the layer of blood vessels between the sclera and the retina.

The signs, symptoms and characteristics of uveitis may include:  Eye redness. Eye pain. Light sensitivity. Blurred vision. Dark, floating spots in your field of vision (floaters). Decreased vision.  Symptoms may occur suddenly and get worse quickly, though in some cases, they develop gradually. They may affect one or both eyes. Occasionally, there are no symptoms, and signs of uveitis are observed on a routine eye exam. The uvea is the middle layer of tissue in the wall of the eye. It consists of the iris, the ciliary body and the choroid. When you look at your eye in the mirror, you will see the white part of the eye (sclera) and the colored part of the eye (iris). The iris is located inside the front of the eye. The ciliary body is a structure behind the iris. The choroid is a layer of blood vessels between the retina and the sclera. The retina lines the inside of the back of the eye, like wallpaper. The inside of the back of the eye is filled with a gel-like liquid called vitreous. The type of uveitis you have depends on which part or parts of the eye are inflamed:  Anterior uveitis affects the inside of the front of your eye (between the cornea and the iris) and the ciliary body. It is also called iritis and is the most common type of uveitis. Intermediate uveitis affects the retina and blood vessels just behind the lens (pars plana) as well as the gel in the center of the eye (vitreous). Posterior uveitis affects a layer on the inside of the back of your eye, either the retina or the choroid. Panuveitis occurs when all layers of the uvea are inflamed, from the front to the back of your eye.  When to seek medical advice Contact your doctor if you think you have the warning signs of uveitis. He or she may refer you to an eye specialist (ophthalmologist). If you're having significant eye pain and unexpected vision problems, seek immediate medical attention.
