Familial pars planitis

Pars planitis has rarely been noted to occur in more than one member of a family. We report the occurrence of this disorder in more than one member of two unrelated families. The affected members of one of these families included a 37-year-old woman and three of her six children. The affected members of the other family were two teenaged brothers. No specific cause for the familial clustering of pars planitis has been identified in the affected members of these families.
