Uveitis is estimated to be responsible for approximately 10% of the blindness in the United States.[citation needed] Uveitis requires an urgent referral and thorough examination by an ophthalmologist, along with urgent treatment to control the inflammation.

Uveitis is usually categorized anatomically into anterior, intermediate, posterior and panuveitic forms.

  • Anywhere from two-thirds to 90% of uveitis cases are anterior in location (anterior uveitis), frequently termed iritis - or inflammation of the iris and anterior chamber. This condition can occur as a single episode and subside with proper treatment or may take on a recurrent or chronic nature. Symptoms include red eye, injected conjunctiva, pain and decreased vision. Signs include dilated ciliary vessels, presence of cells and flare in the anterior chamber, and keratic precipitates ("KP") on the posterior surface of the cornea.
  • Intermediate uveitis consists of vitritis - inflammatory cells in the vitreous cavity, sometimes with snowbanking, or deposition of inflammatory material on the pars plana.
  • Posterior uveitis is the inflammation of the retina and choroid.
  • Pan-uveitis is the inflammation of all the layers of the uvea.

A myriad of conditions can lead to the development of uveitis, including systemic diseases as well as syndromes confined to the eye. In anterior uveitis, no specific diagnosis is made in approximately one-half of cases. However, anterior uveitis is often one of the syndromes associated with HLA-B27. Human Leukocyte Antigen B*27 (subtypes B*2701-2724) is a class I surface antigen encoded by the B locus in the MHC on chromosome 6. ...

  • Posterior segment

The prognosis is generally good for those who receive prompt diagnosis and treatment, but serious complication (including cataracts, glaucoma, band keratopathy, retinal edema and permanent vision loss) may result if left untreated. The type of uveitis, as well as its severity, duration, and responsiveness to treatment or any associated illnesses, all factor in to the outlook.[1] Cataract is also used to mean a waterfall or where the flow of a river changes dramatically. ...

Uveitis is typically treated with glucocorticoid steroids, either as topical eye drops (such as betamethasone, dexamethasone or prednisolone) or oral therapy with prednisolone tablets.
