NBEO Ocular Disease Part 1 Practice Test

Pars planitis is a chronic intermediate uveitis with inflammation centered in the pars plana that often involves the peripheral retina. Classic signs include snowballs in the vitreous and snowbanking along the pars plana. It tends to have a long, chronic course and can be bilateral, and while it can be idiopathic, it may be associated with systemic conditions such as multiple sclerosis or sarcoidosis. Rheumatoid arthritis, however, is not a typical association for pars planitis, making that statement the one that doesn’t fit. The other points—involvement of the pars plana and peripheral retina, the chronicity, and the presence of snowbanking—are consistent features.
