The Iridocyclitis of Early Onset Pauciarticular Juvenile Rheumatoid Arthritis: Outcome in Immunogenetically Characterized Patients

In a cohort of 72 patients with iridocyclitis (iritis) and early onset pauciarticular juvenile rheumatoid arthritis (EOPA-JRA) the course of the eye disease was matched with ocular outcome. Chronicity of inflammation (greater than 6 months/episode) was correlated with complications of eye disease that caused impairment of vision. HLA antigens in these patients were compared with the HLA antigens in a cohort of 77 patients with EOPA-JRA in whom iridocyclitis had failed to develop over a followup of 5 years or longer. HLA-DR5 (11) was correlated with the presence of eye disease, and HLA-DR1 with its absence; HLA-DRw8, which strongly predisposes to EOPA-JRA, was neutral with respect to eye disease.
