Uveitis is the inflammation of the uvea, the pigmented layer that lies between the inner retina and the outer fibrous layer composed of the sclera and cornea. The uvea consists of the middle layer of pigmented vascular structures of the eye and includes the iris, ciliary body, and choroid. The exact cause of uveitis is often unknown, but it can be related to an underlying autoimmune or infectious disease, as well as trauma or exposure to toxins.
Symptoms of uveitis can include eye redness, pain, light sensitivity, blurred vision, and floaters. Diagnosis is typically made through a comprehensive eye exam and may include laboratory tests or imaging studies. Treatment options depend on the underlying cause and severity of the inflammation and may include medications such as corticosteroids, immunosuppressants, or antibiotics. Without prompt treatment, uveitis can lead to complications such as cataracts, glaucoma, or permanent vision loss.
