Uveitis

Uveitis refers to inflammation (irritation) of the part of the eye that supplies blood to the eye, which is the pigmented, vascular part of the eye. The iris (which is the colored part of the eye that forms the pupil), ciliary body and choroid, uvea are one piece, shaped like a hollow ball with a large slit inside. The slit is the pupil, and the rest of the bulb is the iris, ciliary body, and choroid, all "blended" together as vascular cups. Therefore, if the iris becomes inflamed, the ciliary body and choroid may also be slightly or severely affected.

Causes of uveitis:

The cause cannot be determined. However, when a cause can be determined, it is usually trauma, cataracts, infectious disease, or cancer that can cause uveitis. Canine infections include Rocky Mountain spotted fever, Ehrlichiosis, female uterine infections, hepatitis viruses and systemic fungal infections, and possibly Lyme disease and aplasmacytosis. Causes in cats include: feline leukemia virus, feline HIV, FIP virus, bartonellosis, and toxoplasmosis. However, many people with uveitis have no obvious underlying cause.

Clinical symptoms of uveitis:

turbidity, redness, tearing, squinting, eye bleeding and vision loss, strabismus, light sensitivity, redness of the white part of the eye, abnormal pupil shape or size, etc. .

How to treat uveitis:

Treatment depends on the cause. If cancer is present, the affected eye usually needs to be surgically removed unless the cancer is also present elsewhere in the body. If cancer is not present, anti-inflammatory drugs are usually prescribed for topical use and sometimes for oral use. Uveitis can lead to a variety of eye complications, such as cataract formation, scar tissue, retinal disease, and glaucoma. Treatment of uveitis aims to reduce inflammation and prevent complications. Treatment options vary from patient to patient, but typically include steroid eye drops to reduce inflammation, atropine to relieve pain (people with uveitis have terrible headaches!), oral anti-inflammatory medications to reduce inflammation, and possibly medication to prevent glaucoma. Improving immunity is also very necessary.
