Haze to the fluid in the front chamber of the eye (aqueous flare).Cloudiness to the cornea (corneal edema).X-rays or ultrasound to look for cancerĪn eye exam confirms the diagnosis of uveitis – your vet may recommend referral to a veterinary ophthalmologist for a detailed, microscopic examination of the eye and advanced eye testing.Other infectious disease tests based on your geographic area (such as Bartonella, Toxoplasma gondii, or fungal infections).Common tests for cats with uveitis include: A complete physical examination will be performed to detect any signs of body illness, such as a fever or swollen lymph nodes, and your vet may recommend a work-up to determine the cause of the uveitis. Your cat should be examined by a veterinarian if they are showing symptoms of uveitis. Raised third eyelid with sunken eye appearance.If your cat develops uveitis, you may notice some of these clinical signs: Lymphoma is the most common type of body cancer to spread to the eye and cause uveitis in cats. The uvea is a common place for cancers to spread because it has such a good blood supply. Toxoplasmosis (infection caused by Toxoplasma gondii).Feline infectious peritonitis (FIP) coronavirus.Bartonellosis (infection caused by Bartonella).Several types of infections may cause severe uveitis in cats. It often develops into a chronic form of uveitis in middle-aged to older cats. This type of uveitis is also called “idiopathic uveitis” and has no underlying cause for the inflammation. This is the most common type of uveitis in cats, accounting for 60% of uveitis cases not caused by another eye problem. Systemic diseases that cause uveitis in cats include: Immune-mediated Uveitis Feline Post-Traumatic Ocular Sarcoma (FPTOS).The most common types of primary eye tumors in cats include:.The majority of these eye tumors in cats are malignant, meaning they not only grow within the eye, but also spread outside of the eye to other parts of the body (metastasis).These cancers develop first inside of the eye, often within the uvea.Trauma to the eye (blunt or penetrating injury).Ocular diseases in cats that cause uveitis include: Uveitis in cats can be caused by an ocular disease or a systemic disease that affects the eye. The causes of uveitis in cats are diverse and stem from either ocular disease or a systemic disease that affects the eye. If the retina becomes involved in the inflammation, it is called chorioretinitis. Uveitis may only affect the front chamber of the eye, called anterior uveitis, or the back portion of the eye, called posterior uveitis. If the uveitis is severe, actual blood and/or pus may develop in the front chamber. When uveitis develops, inflammatory cells like white blood cells and proteins leak into the aqueous humor, causing a haziness or cloudiness to the fluid – this is the hallmark finding of uveitis and is called an aqueous flare. Normally the aqueous humor in the anterior chamber is very clear, which is important for vision. Uveitis wreaks havoc within the eye causing swelling of the tissues, a reduced ability to produce aqueous humor, and leakiness to the blood vessels. Drainage from the front chamber of the eye happens through a microscopic, specialized drainage system within the base of the iris (the colored portion of the eye). Keep the eye pressure normal: The pressure inside of the eye is a balance between the production of aqueous humor and the drainage of the fluid out of the eye.
Remove unwanted materials: Any unwanted cells or material, along with the natural by-products of metabolism in the eye, are collected in the aqueous humor and are drained out of the eye.This fluid contains nutrition for important parts of the eye, like the lens and the cornea. Produce aqueous humor: The clear fluid in the front chamber of the eye is called aqueous humor.The uvea provides the main blood supply to the inside of the eye and extends from the front chamber of the eye all the way to the back of the eye just under the retina. Uveitis is inflammation on the inside of the eyeball, affecting the part of the eye referred to as the uvea, which includes the iris, the ciliary body, and the choroid.
