A 3-year-old child with newly diagnosed juvenile idiopathic arthritis (JIA) is referred for an initial ophthalmic consultation. The parents are anxious to know the risk of developing uveitis. Which historical information is least helpful in answering their question?
Gender of patient
Antinuclear antibody (ANA) positivity
Number of joints involved
Answer: D) Ocular complaints
Explanation: The majority of patients with JIA-associated uveitis are asymptomatic, and therefore, the presence or absence of symptoms is of limited predictive value. The patients at highest risk of ocular involvement are females with ANA-positive, pauciarticular (four or fewer joints) JIA.
