Uveitis

 The uvea consists of the middle layer of pigmented vascular structures of the eye and includes the iris, ciliary body, and choroid. Uveitis is an ophthalmic emergency and requires a thorough examination by an ophthalmologist or optometrist and urgent treatment to control the inflammation. It is often associated with other ocular problems.

Anterior uveitis (iritis)
1. Burning of the eye
2. Redness of the eye
3. Blurred vision
4. Photophobia
5. Irregular pupil
Signs of anterior uveitis include dilated ciliary vessels, presence of cells and flare in the anterior chamber, and keratic precipitates ("KP") on the posterior surface of the cornea. In severe inflammation there may be evidence of a hypopyon. Old episodes of uveitis are identified by pigment deposits on lens, KPs, and festooned pupil on dilation of pupil.
Busacca nodules, inflammatory nodules located on the surface of the iris in granulomatous forms of anterior uveitis such as Fuchs heterochromic iridocyclitis (FHI).
