What is Uveitis?

Uveitis is inflammation of the middle layer of the eye, which contains much of the eye’s blood vessels. The uvea is the pigmented inside layer of the eye, lying beneath the sclera and cornea, and comprises the iris, choroid, and ciliary body. The term Uveitis is frequently used for any inflammation of the interior of the eye. Infections, injury and autoimmune disorders may be associated with the development of uveitis, though the exact cause is often unknown. Uveitis disrupts vision by primarily causing problems with the lens, retina, optic nerve, and vitreous.

Uveitis FACTS

• According to the CDC (Centers for Disease Control and Prevention), USA, approximately 10% of all cases of blindness in the United States are caused by uveitis.
• Uveitis disrupts vision by primarily causing problems with the lens, retina, optic nerve, and vitreous.
• The National Eye Institute conducts and supports a number of studies investigating uveitis, including, testing new methods for treating uveitis.
• MERSI is actively conducting Researchon Uveitis and offers several clinical trials for this condition

 

Symptoms of Uveitis:

• Blurred vision
• Cloudy vision
• Floaters
• General vision problems
• Eye pain
• Eye redness
• Photophobia – abnormal sensitivity to light
• Headaches
• A small pupil
• Alteration of the color of the iris

Types of Uveitis

• – Anterior uveitis frequently termed iritis. This type affects the front of the eye.
Inflammation of the iris (iritis) is the most common type of uveitis.
• Intermediate uveitis – consists of vitritis, inflammation of the jelly-like part of the eye (vitreous cavity). When there is inflammatory material on the pars plana, the condition is called pars planitis
• Posterior uveitis – inflammation of the retina and choroid. Posterior refers to the back of the eye.
• Pan-uveitis – is when inflammation exists in all layers of the uvea.
