PURPOSE: To prospectively determine the long-term success of medial rectus advancement alone or in combination with other procedures in the management of consecutive exotropia. METHODS: All patients with consecutive exotropia who underwent medial rectus advancement alone or in combination with medial rectus resection or lateral rectus recession or both, performed by a single surgeon between 1999 and 2010, were included. Initially, a retrospective review was performed. Patients were then recalled and examined by a masked observer. Good results were defined as final alignment within 10(Δ) of orthotropia. RESULTS: A total of 46 patients were enrolled in the study with a mean age of 43 ± 15.5 years (range, 14-76) and a mean exotropia of 32 ± 18(Δ) (range, 10-90). Good results were achieved in 33 patients (72%) at a mean follow-up time of 2.5 years. Of the 21 patients returning for prospective examination, 15 (71%) had good alignment at an average follow-up of 4.2 years (range, 6.9 months to 8.6 years). Adduction deficits were improved in 30 of 33 (91%) patients at final follow-up. CONCLUSIONS: In patients with consecutive exotropia, surgery including medial rectus advancement alone or in combination with resection or lateral rectus recession or both usually is effective.
