The term intermediate uveitis is an anatomically based description of the primary site of the ocular inflammation. The inflammation is localized to the vitreous base overlying the ciliary body, pars plana, and peripheral retina, as well as the anterior vitreous (Fig 24-2). Intermediate uveitis accounts for 12%–28% of uveitis cases in the pediatric age group. In children, it may occur with various conditions, including sarcoidosis, syphilis, Lyme disease, multiple sclerosis, and tuberculosis. Idiopathic disease, known as pars planitis, accounts for 85%–90% of cases.
