BACKGROUND: The correction of oculomotor disorder in Grave's disease is applied on pathological extraocular muscles. Based on the global muscular restriction (bilateral forced duction test) and angular measurements, we have used a non-adjustable technique. PATIENTS AND METHODS: We performed a retrospective analysis of 21 patients (23 operations) with thyroid-associated orbitopathy operated for persisting diplopia. The angles of deviation in the 9 diagnostic directions of gaze and the field of binocular vision were measured with the Harm's tangent scale before and after surgery. Sixteen patients were operated only on vertical muscles. The mean follow-up was 45 months. RESULTS: 76 % of the patients (95 % confidence interval [CI], 58-94 %) obtained a large and centred field of binocular vision without prisms. 14 % (95 % CI, 0-29 %) had binocular vision with the use of prisms. Diplopia persisted in one patient despite 3 operations. Taking into consideration the interventions done before the patient was referred to us, the reintervention rate was 13 % (95 % CI, 0-28 %). CONCLUSIONS: A binocular field of vision can be successfully restored in the majority of patients with Graves' orbitopathy, using a non-adjustable surgical technique.
