Given the high predicted uveitis risk for ANA‐positive patients with oligoarthritis, psoriatic arthritis, or undifferentiated arthritis and age at JIA onset ≤6 years, screening for uveitis once every 2 months during the first year after JIA onset, once every 3 months during the second year, and once every 4 months during the third and fourth years seem appropriate. This evidence concerns the gene BTG3 and juvenile idiopathic arthritis.
