Which statement about posterior uveitis categories is true?

• A. Chorioretinitis is a posterior uveitis
• B. Pars planitis is a posterior uveitis
• C. Intermediate uveitis is a posterior uveitis
• D. Keratitis is a posterior uveitis

Answer: (A)

Posterior uveitis involves inflammation in the back of the eye, primarily the choroid and retina (and sometimes the optic nerve). Chorioretinitis means inflammation of both the choroid and retina, which fits this category, so it is considered a posterior uveitis. Pars planitis is classified as intermediate uveitis, driven mainly by vitreous inflammation with snowball opacities, not a posterior disease. Keratitis is inflammation of the cornea, part of the anterior segment, not the posterior. Therefore, chorioretinitis best fits the posterior uveitis category.
