What Is Uveitis?

Uveitis is an inflammation that occurs in the uvea, or the middle layer of the eye. The uvea sits right behind sclera, or white outer layer. The three parts of the uvea are:

• Iris: Colored circle of the eye, that controls the dilation of the pupil
• Ciliary body: The muscle that controls the focusing of the eye’s lens
• Choroid: The layer that contains blood vessels that supply nutrients to the eye

Uveitis can occur in any or all of these parts, and it can affect one or both eyes. No matter which part is affected, it’s crucial to see your eye care provider for treatment that can protect your vision. Untreated uveitis can lead to cataracts, glaucoma, detached retina and damage to the optic nerve.
