Uvea
Definition
The uvea is the middle layer of the eye. It lies beneath the white part of the eye (the sclera). It is made of the iris, ciliary body, and choroid. These structures control many eye functions, including adjusting to different levels of light or distances of objects. Inflammation of one or more of these structures is called uveitis.
