Uveitis is the most common extraarticular manifestation of AS. It is often unilateral, but bilateral uveitis also occurs. Attacks are usually somewhat acute in onset; however, a minority of patients may present with chronic symptoms of blurring and ocular hyperemia.
Clinically evident inflammatory bowel disease is observed in 6%-7% of patients with AS, which is significantly more frequent than in the general population.
Conjunctivitis and scleritis are infrequent ocular manifestations of AS.
