Lee JY, et al. – This paper gauged the effect of initial postoperative deviation on subsequent reoperation in patients with intermittent exotropia. Furthermore, it performed a comparison of the clinical factors and surgical outcomes between the two surgical failure groups. The findings revealed that initial postoperative overcorrection following primary surgery for intermittent exotropia could not speculate long–term success. Hence, a need arose for cautious monitoring for consecutive esotropia, 6 months postoperatively. Annual check–ups were advised for all patients with under– and overcorrections for a period of at least 5 years after surgery.
