Uveitis is a serious eye problem that can damage your vision. It is a redness and swelling (inflammation) of the uvea. The uvea is the fragile tissue just inside your eye’s white outer layer (the sclera). If you have uveitis, you must see an eye doctor (ophthalmologist) right away. You must get treatment to keep your eyesight.
Uveitis has many possible causes, including:
An eye injury
Exposure to toxins
Autoimmune or inflammatory conditions, such as rheumatoid arthritis and inflammatory bowel disease
In many cases, the cause can’t be found.
Uveitis most often inflames the colored part of your eye (iris). This inflammation is called iritis. The iris opens and closes the pupil, the hole through which light enters your eye. Because of this, uveitis can cause pain and sensitivity to light. Often, the eye becomes red. Your vision may get blurry. You may see spots floating in your eye. Uveitis can affect one or both eyes. If it is not treated, it can get worse. It can lead to other eye diseases that affect your vision, such as glaucoma or cataracts. It can even cause permanent vision loss.
