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 follow-up after surgery were included. The age, sex, angle of deviation and stereoacuity of the patients were studied. Surgical success was defined as exodeviation of < 10 PD or esodeviation of < 4 PD at the final visit after the surgery. The correlation between clinical factors and surgical success rate was analyzed by using correlative analysis. Results A total of 129 patients participated in the study. There were 108 (83.7%) and 21 (16.3%) patients in Groups 1 and 2, respectively. There were 89 (82.4%) and 17 (80.1%) patients with surgical successes in Groups 1 and 2, respectively (p = 0.18). Moreover, 13 (12.0%) patients in Group 1 and 3 (14.3%) patients in Group 2 required reoperation, showing no significant difference (p = 0.12). There was no statistically significant correlation between surgical success and preoperative change of angle of deviation < 10 PD (OR = 1.78, p = 0.17). Conclusion Among the patients with basic type of IXT subjected to the analysis, 16.3% had a change of ≥ 10 PD before surgery, and there was no significant correlation between surgical success and preoperative change of angle of deviation.

Background In patients with moderate- to large-angle exotropic deviations, surgical correction remains the definitive treatment. The purpose of this study was to identify preoperative factors that correlate with surgical success and to produce a binomial model that predicts success based on preoperative factors. Methods We performed a retrospective review of patients with intermittent exotropia who underwent uniocular recession-resection surgery. Success was defined as ocular deviation ≤10 Δ exo...

Purpose: We investigated the recommended minimum postoperative follow-up period for the determination of secondary corrective surgery for the consecutive esotropia (ET) and recurrent exotropia (XT) after the first intermittent XT surgery. Methods: The medical records of 728 patients who underwent surgical treatment for intermittent XT between 2004 and 2009 with a minimum postoperative follow-up of 1 year were retrospectively reviewed. Each patient underwent a detailed sensory and motor examinati...

Purpose To describe the long-term surgical outcomes in a population-based cohort of children with intermittent exotropia. Methods The medical records of all children ( Results Of 184 patients with intermittent exotropia, 61 (33%) underwent surgery at a mean age of 7.6 years (range, 3.2 to 23 years). Twelve of the 61 children (19.7%) underwent a second surgery (10 for recurrent exotropia and 2 for consecutive esotropia), and no patient received 3 or more surgeries during a mean follow-up of 10 ye...

Purpose: To determine the result of early surgery for intermittent exotropia for children under 4 year old and the factors which affect it. Methods: The study subjects consisted of 25 children younger than 4 years who had received surgery for intermittent Exotropia. They were followed up for more than 1 year after surgery by the Department of Ophthalmology of the Gachon Medical School, between July 1998 and December 2003. The interval from onset to initial surgery, preoperative deviation angle, ...

Abstract Purpose To determine the factors associated with favorable and less favorable outcomes in strabismus surgery for treatment of exotropia and to show the factors influencing the efficacy of the surgical procedure. Methods Case files of 225 patients with a diagnosis of primary exotropia were evaluated. Information about patient age at onset of deviation, patient age at surgery, interval between onset and surgery, preoperative deviation, refractive errors, degree of anisometropia, visual ac...

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 ...

Purpose: The purpose of this study is to compare the postoperative results of surgery for 60 patients with intermittent exotropia (20-30PD). Methods: They were classified into two groups : one group with bilateral lateral rectus recession (n=34) and another group with unilateral medial rectus resection and lateral rectus recession (n=26). We assessed the postoperative results by comparing the deviation at postoperative 1 year to those at 1day, 1week, 1month, and 6months after surgery. Results: T...

Purpose: Although intermittent exotropia is the most common strabismus of children in Korea, no previous studies have documented the natural course of intermittent exotropia. Therefore, this study was designed to evaluate the natural course of intermittent exotropia in Korean children. Methods: Sixty-two children with intermittent exotropia at the Department of Ophthalmology Chungbuk National University Hospital were selected for this study. Children who were operated or followed up during less ...

Purpose : This study was designed to determine the recurrence rate, the recurrence time after surgical correction of intermittent exotropia and the relationships between the factors and the surgical outcome of ntermittent exotropia. Methods: The surgical results were retrospectively investigated in 210 patients who had undergone surgery for intermittent exotropia with at least 3 months (average 26.3 months, range 165 months) after surgical correction. Surgical success was defined as a final dist...
