Non-infectious uveitis is a type of inflammation of the eye that is not caused by an infection. It is a leading cause of blindness in the United States and can affect any part of the eye, including the iris, ciliary body, and choroid. Symptoms of non-infectious uveitis include redness, pain, blurred vision, and sensitivity to light. Treatment typically involves the use of topical or oral corticosteroids, as well as other medications to reduce inflammation.
