Uvea
Alternate Names : Vascular tunic
Definition
The uvea is the middle layer of the eye beneath the white part of the eye (the sclera). It consists of the iris, ciliary body, and choroid. These structures control many of the functions of the eye such as adjusting to different levels of light or different distances of objects.
