[Uveitis in spondyloarthritis]

Acute anterior uveitis (AAU) is the most frequent uveitis subtype. It is often associated with HLA-B27 and with inflammatory rheumatic diseases, in particular with spondyloarthritis (SpA), which itself is strongly associated with HLA-B27. About 40-60% of patients with AAU have an associated spondyloarthritis, and 20-40% of patients with spondyloarthritis also have uveitis. The incidence of AAU in patients with SpA clearly correlates with disease duration. The AAU has an acute onset, usually affects only one eye at a time, and shows a tendency for recurrence. Early therapy of AAU with topical steroids is relevant for good visual outcomes. Minimum duration of therapy of flares of AAU is 6-8 weeks in order to prevent early recurrency. The rate of local complications correlates with the rate of AAU flares and the visual outcome is often good. Refractory uveitis and frequent recurrencies of AAU may be treated with conventional disease-modifying antirheumatic drugs (DMARDs, such as sulfasalazine and methotrexate) and biologicals (e.g. TNF-alpha inhibitors). Any first episode of AAU diagnosed by an ophthalmologist should prompt referral to rheumatology for suspected SpA, particularly if rheumatic symptoms are present.
