Pars planitis is best described as which type of uveitis?

• A. Posterior
• B. Intermediate
• C. Anterior
• D. Panuveitis

Answer: (B)

Pars planitis is a form of intermediate uveitis. The inflammation primarily involves the vitreous and pars plana, with characteristic findings such as inflammatory cells in the vitreous and aggregates called snowballs, along with exudates forming snowbanks at the pars plana. This places the disease in the middle segment of the eye rather than the anterior segment (iris/ciliary body) or the posterior segment (retina/choroid). Panuveitis would imply involvement of all uveal tracts, which isn’t the defining feature here. Pars planitis is typically noninfectious and often seen in younger patients, reinforcing its classification as intermediate uveitis.
