What is uveitis in horses?

Uveitis in horses is a condition characterized by inflammation of the uvea, which is the middle layer of the eye that includes the iris, ciliary body, and choroid. This inflammation can be caused by a variety of factors, including infections, trauma, autoimmune diseases, and certain systemic diseases. Uveitis can be a painful and potentially vision-threatening condition if left untreated, and can lead to symptoms such as squinting, tearing, sensitivity to light, and cloudiness of the eye. Treatment typically involves addressing the underlying cause of the inflammation and providing medication to reduce inflammation and manage pain.
