Uvea - English Definition & Meaning

Definition

The uvea is the middle layer of the eye, located between the sclera (the white outer layer) and the retina (the inner, light-sensitive layer). It's made up of three parts: the iris, the ciliary body, and the choroid. Think of it as the eye's vascular core, providing blood supply to other parts. The iris controls the size of the pupil, the ciliary body produces aqueous humor and helps with focusing, and the choroid nourishes the retina. Inflammation of the uvea, called uveitis, can cause serious vision problems. This crucial layer maintains the health and functionality of the eye.

Etymology

The word 'uvea' comes from the Latin word 'uva,' meaning 'grape.' This is because when the outer layers of the eye (the sclera and cornea) are removed, the remaining pigmented layer resembles a dark purple grape. The term was adopted into anatomical terminology to describe this specific layer of the eye. This etymological connection highlights the visual similarity that early anatomists observed.
