Purpose: To investigate the long-term clinical course of intermittent exotropia after surgical treatment to determinewhether and when postoperative exo-drift stabilizes, and the required postsurgery follow-up duration incases of intermittent exotropia. Methods: We retrospectively reviewed the medical records of patients diagnosed with intermittent exotropiawho underwent surgical treatment between January 1992 and January 2006 at Yeungnam University Hospitaland postoperatively performed regular follow-up examinations for up to 7 years. We also analyzed the differencein exo-drift stabilization, according to surgical procedure. Results: A total of 101 patients were enrolled in the study. Thirty-one patients underwent lateral rectus recessionand medial rectus resection (R&R) and 70 patients underwent bilateral lateral rectus recession (BLR). Thepostoperative angles of deviation increased significantly during the initial 36 months, but no subsequent significantchanges were observed for up to 84 months. Follow-ups for 7 years revealed that more than 50% of thetotal amount of exo-drift was observed within the first postoperative year. In addition, the angles of deviation at1 year correlated with those at 7 years postoperatively (Pearson correlation coefficient r = 0.517, p < 0.001). Nosignificant exo-drift was observed after 36 months in patients who underwent BLR, whereas after 18 monthsin patients who underwent R&R. Conclusions: The minimum postoperative follow-up required after surgical treatment to ensure stable results is36 months. In particular, careful follow-up is necessary during the first postoperative year to detect rapid exodrift. Patients who underwent BLR required a longer follow-up than those who underwent R&R to ensure stablepostoperative alignment.
