Abstract Objective To investigate the surgical outcome according to the angle of deviation at postoperative day 1 in patients with recurrent exotropia Design Retrospective case series Methods Surgical outcome in patients with recurrent exotropia for at least 1 year was analyzed retrospectively. Patients were divided into 3 subgroups according to the angle of deviation at postoperative day 1: overcorrection group (≥2 prism diopter [PD] of esodeviation), orthotropic group (orthotropia or Results One hundred and six patients were included in this study. Age at surgery was 11.8 ± 6.9 years, and preoperative angle of deviation was 22.9 ± 6.3 PD at distant. Patients were followed-up for 24.4 ± 12.8 months. There were 20 (18.9%), 82 (77.4%), and 4 (3.8%) patients in overcorrection, orthotropic, and undercorrection groups at postoperative day 1 ( p = 0.001). The surgical success rate at the final visit in the overcorrection group (95%) was higher than that in orthotropic and undercorrection groups (76.8% and 25%, respectively, p = 0.004). In univariate regression analysis, overcorrection at postoperative day 1 was the only reliable factor for long-term success (odds ratio [OR] = 24.101, p = 0.01). Conclusion Overcorrection at postoperative day 1 is a good surgical predictor of successful outcome in surgery for recurrent exotropia.

Purpose To report the results of surgical treatment for intermittent or constant comitant exotropia in adults and to examine the factors associated with the surgical outcome. Methods The medical records of consecutive patients older than 18 years of age at the time of surgery for intermittent or constant comitant exotropia and with at least 1 year's follow-up were retrospectively reviewed. Surgical success was defined as postoperative esodeviation of Δ , orthotropia, or exodeviation of Δ . Overc...

Purpose To determine if achieving the ideal postoperative target range increases the long-term success of pediatric strabismus surgery. Design Interventional case series. Methods Children below 12 years old with horizontal strabismus who underwent surgical correction by recession, resection, advancement, or a combination of both between 1996 and 2011 were included. Alignment was measured within 1 week and at a minimum of 6 months after surgery. The ideal postoperative target range was defined as...

Purpose To compare the outcomes of unilateral lateral rectus muscle re-recession and medial rectus muscle resection for treatment of recurrent or persistent exotropia. Design Retrospective nonrandomized clinical trial. Methods setting: Hospital-based clinical practice. patient population: Forty patients with recurrent or persistent exotropia following bilateral lateral rectus muscle recessions. intervention: Fourteen patients were treated with unilateral medial rectus muscle resection and 26 wit...

Purpose. To evaluate the surgical outcomes of unilateral or bilateral medial rectus (MR) muscle resection for recurrent exotropia after bilateral lateral rectus (BLR) muscle recession based on a novel surgical formula. Methods. Forty-one consecutive patients with unilateral or bilateral MR muscle resection for recurrent exotropia after BLR muscle recession were included in this retrospective study. All surgeries were performed according to the formula: 1.0 mm MR muscle resection for every 5 pris...

Purpose To investigate the effect of initial postoperative minimal overcorrection on the result of the surgical management of intermittent exotropia based on long-term follow-up results. Methods 111 patients who underwent surgery for intermittent exotropia and were followed up for at least 5 years after surgery were retrospectively reviewed. The outcome was judged to be successful when there was 10 prism dioptres (PD) or less of exodeviation and less than 5 PD of esodeviation without any reopera...

Purpose To compare outcomes after bilateral and unilateral medial rectus (BMR/UMR) resection for the treatment of recurrent exotropia after bilateral lateral rectus (BLR) muscle recession. Design Retrospective, cohort study. Methods Forty-four patients underwent BMR resection (BMR group) or UMR resection (UMR group) for recurrent constant exotropia of 25 prism diopters (PD) or less at distance after undergoing BLR muscle recession for intermittent exotropia in an institutional setting. The main ...

Top of pageAbstract Purpose Few reports have included large numbers of exotropia patients. Thus, we undertook this study to perform a survival analysis of over 350 patients with exotropia and to determine which factors might affect the outcome of exotropia surgery. Methods The clinical records of 365 patients who underwent exotropia surgery by one surgeon were retrospectively reviewed. Preoperative patient characteristics, surgical procedures performed, and early postoperative ocular alignment w...

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: To evaluate the success rate of 5 mm resection of one medial rectus (MR) as the second surgery for intermittent exotropia of childhood after bilateral lateral rectus recessions and after unilateral lateral rectus recessions, and to propose a theory of how this surgery works. CASES: The author performed a retrospective chart review of 10 years experience of routinely performing a 5 mm resection of one medial rectus as the second surgery for exotropia recurrent after unilateral or bilater...

Abstract To review and determine the long term outcome of surgery for intermittent exotropia in children. A total of 666 cases were reviewed. They were 15 years old or younger and underwent surgery for intermittent exotropia during the preceding 22 years. Bilateral recession of the lateral rectus muscles was performed in 349 cases. Unilateral recession of the lateral rectus and resection of the medial rectus muscles was performed in 298 cases. One and four muscle procedures were performed in 19 ...

We investigated the period of postoperative exodrift during follow-up and clinical factors that affect the rate of exodrift after surgery in the patients with intermittent exotropia (IXT). A retrospective review of medical records of patients with exodrift who underwent bilateral rectus recession for IXT was performed. Exodrift was defined as angle of deviation greater than 10 prism diopters (PD) at distance and near. The median survival period of postoperative exodrift was analyzed using Kaplan...
