Uveitis

What is it? 
The canine and feline eye contain 3 different structures that when combined make up the Uveal Tract. The Iris is a muscle that forms the pupil of the eye, the Ciliary Body produces the fluid inside the eye and the Choriod Layer provides blood and nutrients to the retina. The inflammation of the structures is called Uveitis.

There are many possible causes for Uveitis, and in many cases the cause may never be known. These can include:

1. Immune mediated
2. Infections from bacterial, viral or fungal sources
3. Trauma
4. Cataracts
5. Neoplasia

What are possible complications of Uveitis?

1. Secondary glaucoma – Inflammatory cells can block the drainage angle of the eye, leading to increased eye pressure (glaucoma), pain and blindness
2. Retinal detachment – Chronically low intraocular pressure can lead to retinal detachment and blindness.
