What does uveitis mean?
Uveitis is the medical term for inflammation of the uvea, the vascular middle layer of the eye. The uvea comprises the iris, ciliary body, and choroid, so uveitis can affect the front or back of the eye and may occur in several distinct forms. Anterior uveitis, posterior uveitis, and panuveitis are common classifications based on location and extent. Symptoms can include redness, eye pain, sensitivity to light, and blurred or distorted vision, although the presentation varies. Uveitis may be associated with infections, autoimmune disorders, injuries, or other conditions, and its cause is not always identified. Prompt diagnosis is important because persistent inflammation can cause complications such as glaucoma, cataract, or permanent visual impairment. The word belongs primarily to medicine rather than everyday vocabulary, but it is useful for understanding a broad range of inflammatory eye conditions and the anatomical layer responsible for them.

"Uveitis may cause pain, redness, light sensitivity, and blurred vision."
The plural occurs in specialist and clinical writing; general usage more often treats the condition as a mass noun and uses the singular form.
"Severe uveitides may require immunosuppressive treatment."
Behind the familiar “eye” sound in uveitis lies the uvea—the eye’s middle layer, whose Latin name literally means “grape.”

Etymology of uveitis
Uveitis was formed in medical Latin from uvea, the name of the eye's vascular middle layer, together with the Greek-derived suffix -itis, meaning inflammation. Medieval Latin uvea came from Latin uva, “grape,” a reference to the structure's grape-like appearance. The same root produced related English forms such as uveal and uveous.
How uveitis is actually used
Uveitis is primarily a medical term used in clinical and specialist contexts. It may refer to inflammation limited to one part of the uvea or involving the entire uveal tract; the part affected is usually specified when relevant.
Easily confused with uveitis
Iritis specifically means inflammation of the iris and often corresponds to anterior uveitis, whereas uveitis is the broader term for inflammation anywhere in the uveal tract.
