The uvea consists of the iris, ciliary body, and choroid, and it provides most of the blood supply to the retina.<unk>  may occur in either eye or both eyes.<unk>  may be classified into the following forms, depending on which part of the uvea is primarily affected by the inflammation:
Anterior<unk>  involves inflammation in the front part of the eye.  It is the most common form of<unk> , making up 40-70% of all<unk>  cases.   It is often called iritis because it is usually only effects the iris.
Intermediate<unk>  (also known as cyclitis, pars planitis, or vitritis) involves inflammation of the ciliary body, the vitreous humor, and the front end of the retina.  This is the least common form of<unk> , constituting 7-15% of cases.
Posterior<unk>  (also known as choroiditis if just the choroid is involved, or chorioretinitis if the retina is also involved) affects the back part of the uvea and involves primarily the choroid, a layer of blood vessels and connective tissue in the middle part of the eye. It can also involve inflammation of the retina and optic nerve.  It makes up 15-22% of all<unk>  cases.
