What is uveitis and which part of the eye does it primarily affect?

• A. Inflammation of the retina; affects retina
• B. Inflammation of the uveal tract (iris, ciliary body, choroid); can be anterior, intermediate, or posterior
• C. Inflammation of the optic nerve
• D. Inflammation of the sclera

Answer: (B)

Uveitis is inflammation of the uveal tract, the middle layer of the eye made up of the iris, ciliary body, and choroid. This inflammation can occur in different regions: anterior uveitis affects the iris and/or ciliary body, intermediate uveitis involves the vitreous area near the lens, and posterior uveitis targets the choroid at the back of the eye. When multiple parts are involved, it’s called panuveitis. This is distinct from inflammation of the retina, optic nerve, or sclera, which involve those tissues rather than the uveal tract.
