Vascular layer of eyeball
Tunica vasculosa bulbi oculi
- Latin synonym: Uvea; Tunica media bulbi oculi
- Synonym: Uvea; Middle layer of eyeball
Definition
The vascular tunic of the eye is formed from behind forward by the choroid, the ciliary body, and the iris.
The choroid invests the posterior five-sixths of the bulb, and extends as far forward as the ora serrata of the retina. The ciliary body connects the choroid to the circumference of the iris. The iris is a circular diaphragm behind the cornea, and presents near its center a rounded aperture, the pupil.
