Antinuclear antibodies in arthritic and nonarthritic children with uveitis.

We determined whether a positive test for antinuclear antibodies correlated with uveitis only in children with juvenile rheumatoid arthritis (JRA) or whether they also represented a serologic marker for isolated idiopathic chronic uveitis in children. We conclude that the immunopathogenesis of uveitis associated with JRA is different from that of idiopathic chronic uveitis.
