Uveitis is inflammation inside the eye, specifically affecting one or more of the three parts of the eye that make up the uvea: the iris , the ciliary body , and the choroid. The eye is shaped like a tennis ball with three different layers surrounding a gel-filled caviety. The impetus for this project came from owners across the country seeking information on this disease and pooling their knowledge to help each other. The choroid is a pigmented layer to prevent the light from entering the eye other than through the pupil. It also contains blood vessels which nourish the retina by diffusion. Anterior uveitis refers to inflammation of the iris alone or the iris and ciliary body; anterior uveitis is the most common form. In surveys of the causes of blindness uveitis has usually not been included and is probably underestimated. Inflammation of the uvea may involve other parts of the eye, or any part of the eye, including the cornea , the sclera , the vitreous body, the retina and the optic nerve. Intermediate uveitis - this affects the area behind the ciliary body, as well as the retina and the most forward edge of the retina . Symptoms include decreased vision, pain, redness, photophobia, and floaters.

Uveitis also is found in association with autoimmune disorders, such as systemic lupus erythematosus and rheumatoid arthritis.Symptoms include decreased vision, pain, redness, photophobia, and floaters. The uvea extends toward the front of the eye and consists of the iris, choroid layer and ciliary body. Uveitis requires an urgent referral and thorough examination by an optometrist or an ophthalmologist, along with urgent treatment to control the inflammation.The material included here will serve to provide information about the wide range of causes, methods of treatment and means of handling equine recurrent uveitis.
