Uveitis is an inflammation of the uvea, the middle layer of the eye, which includes the iris, ciliary body, and choroid. This condition can cause redness, pain, light sensitivity, and blurred vision. Uveitis can affect one or both eyes and may develop suddenly or gradually. The causes of uveitis can vary and include infections, autoimmune diseases, or exposure to toxins. Treatment often involves corticosteroids to reduce inflammation and may include other medications depending on the underlying cause. Early diagnosis and treatment are essential to prevent complications, such as vision loss.
