Uveitis is a form of eye inflammation that affects the uvea, which is the middle layer of tissue in the wall of the eye. This swelling may also affect the lens, retina, optic nerve, and vitreous.
Symptoms of uveitis may include redness in the eye, pain, and blurry vision. Possible causes may include infection, injury, or an autoimmune or inflammatory disease. Early diagnosis and treatment are important to prevent potential permanent vision loss.
