The median ESR and CRP of patients with uveitis of established cause were higher than the median ESR and CRP of patients with unknown uveitis (17.0 mm/h, range 1–120 mm/h vs. 11.0 mm/h, range 1–140 mm/h for ESR and 3.4 mg/L, range 0.4–262.0 mg/L vs. 1.9 mg/L, range 0.3–229.0 mg/L for CRP; P = 0.015 for both, Mann-Whitney U test). This evidence concerns the gene CRP and uveitis.
