BACKGROUND: Scott described a method of achieving the effect of a posterior fixation procedure by combining resection and recession of a rectus muscle, while maintaining the ability to adjust primary position alignment with adjustable sutures. METHODS: A retrospective review of combined recession-resection procedures on rectus muscles between 1998 and 2002 was carried out. RESULTS: We identified 22 patients, 17 females and 5 males. The mean age at presentation was 44 years. The etiology was felt to be paralytic in seven patients (31.8%), mechanical/restrictive in seven patients (31.8%), and due to residual childhood strabismus in eight patients (36.4%). Twenty patients had undergone previous strabismus surgery, ranging from one to six operations (mean, 1.75). Scott procedures were performed on 25 rectus muscles of 22 patients; 12 on the lateral rectus muscles, 7 on the inferior rectus muscles, 3 on the medial rectus muscles, and 3 on the superior rectus muscles. All but one patient had a measurable improvement in gaze incomitance, and 11 of 12 who had a measurement of the field of binocular single vision showed improvement. Twenty patients had follow-up periods of 3 months or more, with a range of 3 to 30 months and a mean of 9.35 months. CONCLUSIONS: The combined recession-resection procedure advocated by Scott has a role in the management of incomitant strabismus.
