Uveitis Guide, Meaning , Facts, Information and Description

Definition

Uveitis specifically refers to inflammation of the middle layer of the eye, termed the "uvea" but in common usage may refer to any inflammatory process involving the interior of the eye.

Uveitis is estimated to be responsible for approximately 10% of the blindness in the United States. Uveitis requires a thorough examination by an ophthalmologist.

types

• Anywhere from two-thirds to 90% of uveitis cases are anterior in location, 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.
