(Greek: a suffix; inflammation, burning sensation; by extension, disease associated with inflammation)
This suffix has come to mean "inflammation of" but originally it meant "pertaining to" or "of the". The Greek word nosos ["disease"] was either expressed or understood, although it might not be included with the basic element. For example, bursitis nosos would mean "disease of the bursa".
2. A nonspecific or general term for any intraocular inflammatory disorder or any part of the uveal tract: The uveal tract structures (iris, ciliary body, and choroid) are usually involved in uveitis, but other nonuveal parts of the eye, including the retina and cornea, may also be involved.
Uveitis that is not associated with known infections, or that is associated with diseases of unknown cause, is termed endogenous uveitis. This is thought to be due to an autoimmune phenomenon.
