Abstract
Purpose: We performed this study to evaluate the occurrence of consecutive esotropia after early surgery in the patients with intermittent exotropia less than 4 years of age. Methods: We analyzed the surgical results of 37 patients who underwent surgery before 4 years of age retrospectively. They were followed up at least more than 1 year after surgery. The orthophoria was defined as an exophoria of 0 to 12PD or an esophoria of 0 to 5PD after surgery. The consecutive esotropia was defined as an esodeviation lasting more than 3 months that needed surgical correction due to sensorial deterioration. Results: Preoperative angle of exodeviation at distance ranged from 20PD to 60PD (mean 35.19.2PD). Twenty-seven of 37 patients (75.7%) showed orthophoria after surgery in 1 year follow-up and 20 of 31 patients (64.5%) in 2 years follow-up. Five patients (13.5%) showed recurrence and 4 patients (10.8%) consecutive esotropia. Immediate postoperative overcorrection was 14.18.7PD(0-30) in patients who were orthophoric after postoperative follow-up more than 2 years. The rate of consecutive esotropia was high in patients with an exo-angle of 30PD or more and a large amount of recession of lateral recti more than 7mm. Conclusions: This study revealed that consecutive esotropia after early surgery for intermittent exotropia less than 4 years of age was noted to the 10.8%.

Purpose The correlation between the existence of the preoperative condition of ≥ 10 prism diopter (PD) in patients with basic type of intermittent exotropia (IXT) and postoperative outcomes was analyzed. Method The medical records of patients that underwent surgery for IXT were analyzed retrospectively. The analysis was conducted by dividing the patients into a group with change of < 10 PD (Group 1) and ≥ 10 PD (Group 2) before the time of the surgery. Patients who received at least 6 months of ...

Purpose To determine whether age at surgery influences postoperative outcome in infantile exotropia. Methods This longitudinal, retrospective study included children who underwent bilateral lateral rectus recession between 2004 and 2012 for an exotropia with onset by 12 months of age. Surgical outcomes were considered failures if recurrence with exodeviation of >8Δ or overcorrection with esodeviation of >5Δ developed during postoperative period. Univariate and multivariate analyses were conducte...

ABSTRACTPurpose: To investigate the long-term outcomes of intermittent exotropia surgery for children less than 4 years of age.Materials and Methods: Consecutive patients who underwent surgery for intermittent exotropia and had follow-up durations longer than 2 years were recruited. The patients were classified according to age at surgery—the patients of group 1 had undergone surgery before 4 years of age and those of group 2 at or after 4 years of age. Motor success was defined by exodeviation ...

Purpose: We performed this study to evaluate the surgical outcome of exotropia in children younger than 10 years with a short, preoperative work-up. Methods: The study subjects included 18 children who had received surgery for exotropia with preoperative work-ups less than 3 months. They were followed for more than 3 months after surgery. The age, symptoms, visual acuity, refractive errors, binocularity at surgery, and surgical results were analyzed. Results: The average age of the subjects was ...

While intermittent exotropia (X(T)) recurs in 20~30% of patients after surgery,1-11 consecutive esotropia (ET) arises in 2~20% because of overcorrection.12-16 Once consecutive ET has occured, the patient can suffer from cosmetic problems and diplopia. Moreover, suppression, amblyopia, and deterioration of stereovision may occur later.17 Lateral incomitancy, medial rectus muscle contracture, and overcorrection of at least 20 prism diopters (PD) immediately after surgery have been reported as risk...
