Type of disease: Rare conditions
Uveitis is inflammation of the middle layer of the eye called the uvea. The uvea consists of the layer and structures beneath the white of the eye. The uvea is made up of the iris, the choroid layer, and the ciliary body. The iris is the colored part of the eye, the choroid layer is the layer of blood vessels and connective tissue, and the ciliary body is the structure in the eye that releases the transparent liquid in the eye. The cause of uveitis is unknown but may be associated with infections, injury, inflammatory and autoimmune disorders, and certain cancers that can affect the eye. Symptoms include eye pain and redness, blurred vision, seeing floaters, light sensitivity, decreased vision, and a whitish area on the inside of the lower part of the iris.
