ABSTRACT
Uvea is the collective term traditionally used to describe the central vascular layer of the eye. The uvea is divided anatomically into three parts: anterior iris, intermediate ciliary body, and the posterior choroid (188). The ciliary body is further delineated by an anterior portion, the pars plicata, and a posterior portion, the pars plana. The functions of the uvea include thermoregulation, production of the aqueous fluid, and nutritional support for the structures of the eye. Over 95% of the blood flow to the eye is distributed throughout the uvea with a majority transported through the choroid.
