Key clinical point: Among patients with ankylosing spondylitis or undifferentiated spondyloarthritis who had not recently experienced anterior uveitis, risk was highest with secukinumab and etanercept.

Major finding: After excluding patients who had experienced anterior uveitis in the past year, secukinumab and etanercept carried higher adjusted risks for first on-treatment anterior uveitis (hazard ratios, 2.23 and 1.80, respectively) relative to adalimumab.
