uveal

Uveal is a specialist medical adjective meaning of or relating to the uvea, the pigmented, blood-vessel-rich middle layer of the eyeball. The uveal tract comprises the iris, ciliary body, and choroid, and the adjective is common in terms such as uveal melanoma, uveal inflammation, and uveal effusion. In general use, the word is uncommon, but it is important in ophthalmology because the uvea can be affected by inflammation, melanoma, and other disorders. Uveal should be distinguished from uvea: uvea is the noun naming the anatomy, whereas uveal functions as its modifier. The word has a striking history: the Latin anatomical term uvea literally means “grape.” Uveal is therefore especially useful to readers who encounter the eye’s layered anatomy in clinical or scientific writing, while uvea and uveal tract are the clearer terms for the structures themselves.

The same Latin grape word underlies uvula (“little grape”), while uveitis and uveoma are later medical formations based on uvea.
