Eye Health and Uveitis

Uveitis (pronounced you-vee-EYE-tis) is basically an inflammation of the eye. The condition involves all inflammatory processes of the middle layers of the eye, also called the uveal tract or uvea. The uvea includes the iris (colored part of the eye), choroid (a thin membrane containing many blood vessels), and ciliary body (the part of the eye that joins these together).

The uvea is very important because its many veins and arteries transport blood to the parts of the eye that are critical for vision.

What Are the Symptoms of Uveitis?

Symptoms of uveitis may include:

• Eye redness and irritation.
• Blurred vision.
• Eye pain.
• Increased sensitivity to light.
• Floating spots before the eyes.

Uveitis may develop rapidly, and it is very important that you see your ophthalmologist for a complete eye exam if you develop these symptoms, especially if a painful, red eye does not clear up quickly.

Left untreated, uveitis may permanently damage your vision.

What Causes Uveitis?

Uveitis has many potential causes, including infection with a virus, fungus, bacteria or parasite, inflammatory disease affecting other parts of the body, or injury to the eye.

There are four types of uveitis:

• Iritis is the most common form of uveitis. It affects the iris and is often associated with autoimmune disorders such as rheumatoid arthritis. Iritis may develop suddenly and may last up to eight weeks, even with treatment.

How Is Uveitis Diagnosed?

Uveitis can permanently damage your eyesight and even cause blindness. Therefore, if you have any symptoms of uveitis, is very important for you to see your ophthalmologist right away.
