Recurrent posterior scleritis--report of a case.

Posterior scleritis is a serious ocular inflammatory and potentially blinding disorder. It is uncommon and often under-recognized due to its varied presentations, and general ophthalmologists are not familiar with it. Posterior scleritis may be idiopathic or associated with systemic diseases. Visual disturbances such as blurring or distortion are the commonest symptoms. There may be pain, tenderness, and deep-seated discomfort in and around the orbit. One study reported a 49% recurrence rate of posterior scleritis. Posterior scleritis responds well to systemic nonsteroidal anti-inflammatory agents, systemic steroids, and immunosuppressive agents. Recurrences are known to occur despite therapy. However, multiple recurrences in posterior scleritis are uncommon. We report a patient with posterior scleritis who had one episode in the right eye and four episodes in the left eye over a 35-month period.
