Brown's syndrome (superior oblique tendon sheath syndrome) presents as an inability to raise the adducted eye and a positive forced duction test. Since first recognized in 1950, this syndrome has been the subject of much controversy concerning its etiology and consequent treatment. Catagorized by Brown himself into true, simulated, acquired, intermittent and spontaneous recovery cases, the origins for this mobility anomaly range from a short anterior sheath of the superior oblique tendon to stenosing tenosynovitis and trauma. Treatment is difficult and is accomplished largely by tenotomy or tenectomy. This article provides the reader with an overview of the syndrome, its signs, history of etiology, prognosis and treatment.
