Uveitis is inflamation of the iris, ciliary body, and choroid. These major structures of the eye are very sensitive and perform numerous functions required for vision.

Uveitis is described in 3 ways:
Anterior uveitis: the iris and ciliary body are affected.
Posterior uveitis: the choroid is affected.
Uveitis: the iris, ciliary body, and choriod are affected.

Causes include inflammation, infection, immune-mediated reactions (a complex allergic-type reaction), and injuries.

Uveitis is painful and can cause blindness.

The cause determines the treatment used and may range from routine outpatient therapy to intense and complex procedures requiring hospitalization. Special diagnostic tests are sometimes required. Specific attention is given to pain control, and any factors that cause further irritation should be eliminated or avoided. These include wind, dirt, sand, sprays, smoke, and bright light.

Notify your veterinarian if a sudden change is noted in the appearance of the eye(s).
