Uveitis in dogs and cats is a common eye disease that mainly affects the iris, ciliary body and choroid tissue, causing inflammation.

This disease can be caused by a variety of reasons, including infection, autoimmunity, tumors, trauma, etc. Symptoms of uveitis in dogs and cats include redness of the eyes, tearing, pain, decreased vision, etc.

Treatment principles include mydriasis treatment, local and systemic antibiotic treatment, and targeted treatment according to the specific cause.

Function:

Iris

The amount of light entering the retina can be adjusted by changing the size of the pupil. It is equivalent to the "aperture" in a camera.

Ciliary body

In addition to producing aqueous humor that nourishes the eye tissues, it also plays a role in supporting the lens.

Chrooid

It is a vascular-rich tissue that plays a role in providing nutrients and oxygen to the outer layer of the retina.

Causes of canine uveitis:

Infection; such as bacterial, fungal, and viral infections.

Trauma; such as cat scratches.

Abnormal metabolism; such as diabetes, hyperlipidemia, hypertension, and blood coagulation failure.

Immune abnormalities;

Various eye tumors or metastatic tumors. Melanocytoma is one of the most common tumors in the eye. Lymphoma is a metastatic tumor that can also cause uveitis.

Inheritance; Golden Retriever is a breed that is prone to pigmentary uveitis. In addition, it is understood that Akita dogs, Samoyeds, etc. are prone to Koyanagi-Harada syndrome.

Other eye diseases; Various eye diseases, such as keratitis, scleritis, and corneal ulcers, can all lead to secondary uveitis.

Causes of feline uveitis:

Infection: Bacterial and fungal infections are common causes, especially anterior uveitis.

Autoimmunity: Autoimmune diseases, tumors (such as melanoma, intraocular lymphoma), etc.

Trauma: Including corneal ulcers, blunt or penetrating eye trauma, etc.

Others: Including breed-related uveitis syndrome, systemic diseases (such as hypertension, coagulation dysfunction), etc.

Symptoms: include redness, tearing, pain, decreased vision, etc.

Diagnosis: The diagnosis is made through clinical manifestations, the strength of the pupil's reaction to light, and whether the humoral fluid is turbid.

The treatment of uveitis in dogs and cats needs to be based on the specific cause. Early diagnosis and timely treatment are essential to prevent complications and protect vision. If your pet has symptoms of eye discomfort, it is recommended to seek medical attention in time so that a professional veterinarian can diagnose and treat it.
