We report three cases of female patients who presented a first episode of unilateral scleritis or acute anterior uveitis while they were treated for 12-16 months by TNF inhibitor: etanercept (Enbrel((R))) 25mg twice weekly for rheumatologic diseases (rheumatoid arthritis or ankylosing spondylitis). Ocular inflammation was resistant to the usual treatment. Some cases of scleritis and uveitis are known to be drug-induced. TNF inhibitors seem to be part of them. Ocular inflammation is usually the first episode. It appears generally in the first year of the treatment by TNF inhibitors and resists to usual treatment. The general disease is usually well stabilized. In our cases, inflammation decreased only when the etanercept was discontinued.
