Purpose To analyse the characteristics of children who had maintained the successful outcome at 2 years after surgery for intermittent exotropia. Methods A retrospective study was performed in 216 patients who had undergone intermittent exotropia surgery and had had at least 2 years of follow-up. Surgical outcomes were grouped, according to the angle of deviation at postoperative 2 years, as success (esophoria/tropia ≤ 5 prism dioptres (PD) to exophoria/tropia ≤ 10PD), recurrence (exotropia > 10PD or reoperation within 2 years) or overcorrection (esophoria/tropia > 5PD). We investigated various clinical factors for their possible associations with the surgical outcomes. Results Of the 216 patients, 128 (59%) were assigned to the success group, and 84 (39%) to the recurrence group. According to a univariate analysis, surgical method and the angle of deviation at the postoperative day 1 showed statistically significant associations with the surgical outcome for intermittent exotropia. However, in the results of a logistic regression test, the angle of deviation at distance at postoperative day 1 was the only factor showing a significant association (p = 0.023). Conclusions Early postoperative overcorrection was significantly associated with the maintenance of successful surgical outcome of intermittent exotropia at postoperative 2 years.

Surgical treatment of childhood intermittent exotropia (XT) is associated with high recurrence rates. In addition, the natural history of intermittent XT has not been rigorously studied and, anecdotally, some cases resolve without surgery. We compared long-term cure rates in children with surgically and non-surgically managed intermittent XT. Children undergoing surgery for intermittent XT who had 5 years follow-up were retrospectively identified. A non-surgical cohort of comparable children was...

Aims To classify patients with intermittent exotropia (IXT) according to the level of near stereopsis, evaluate postoperative stereoacuity and assess the surgical outcomes among groups. Methods The records of 137 patients with IXT were reviewed. Patients were divided into three groups based on the degree of stereopsis: good (40–60 arcsec), moderate (80–200 arcsec) and poor (>200 arcsec). These groups were compared with each other with respect to preoperative and postoperative clinical features. ...

Background Esotropic overcorrection on postoperative day 1 after surgery for intermittent exotropia is generally thought to increase the likelihood of long-term satisfactory alignment; however, it is unclear why some patients who are initially overcorrected demonstrate recurrent intermittent exotropia whereas others maintain esotropic to orthotropic alignment. Methods The records of all patients who underwent primary surgical correction of intermittent exotropia were reviewed; those with any deg...

Purpose To investigate the course of near stereoacuity in a cohort of children with untreated intermittent exotropia. Methods A total of 95 children ages 2-16 years with untreated intermittent exotropia were identified who had measurements of near stereoacuity using the Preschool Randot (PSR) test on at least 2 successive examinations, with no intervening treatment. Deterioration was defined as a drop of at least 3 octaves, as determined by test–retest data. Alternative secondary analyses were p...

Purpose To determine the relationship between initial postoperative deviation and long-term results after surgery for intermittent exotropia. Methods A nonrandomized, retrospective case series. The records of patients who underwent surgery for intermittent exotropia between 2002 and 2006 and had 2 or more years of follow-up were evaluated. Distance alignment at postoperative week 1 was used to predict long-term surgical outcomes. A successful outcome was defined as no recurrence of exodeviation ...

Purpose To examine long-term surgical success rates (>10 years) for patients with intermittent exotropia and the risk factors for failure of surgery in these patients. Methods An attempt was made to contact all patients who underwent surgical treatment for intermittent exotropia between the years of 1970 to 1998 with a minimum postoperative follow-up of 10 years. Each patient underwent a detailed sensory and motor examination, including measurements of near and distance stereoacuity, cover testi...

Purpose While initial overcorrection after exotropia-correcting surgery is widely accepted for a favorable long-term outcome, some have not advocated such overcorrection in younger children owing to concerns regarding rapid deterioration of bifixation ability. This study aimed to evaluate the relationship between initial overcorrection after intermittent exotropia surgery and the surgical outcome in patients aged <4 years. null null Methods In this retrospective study, 391 patients who had under...

Purpose. To evaluate whether clinical measures of postoperative binocular functions could predict the long-term stability of postoperative ocular alignment in children with intermittent exotropia. Methods. A retrospective study was performed in thirty-nine children (median: 7 years) who have been surgically treated from intermittent exotropia without overcorrection (less than 10 prism diopters [pd] of exodeviation at 1 month postoperatively). Angles of deviation and binocular functions were meas...

In this paper the optimum timing for the postoperative functional cure of basic intermittent exotropia is explored based on support vector machine (SVM). One hundred and thirty-two patients were recruited in this prospective cross-sectional study with 6 months of follow-up. Examinations included angle of deviation, central and peripheral fusion, controllability, and near and distance stereopsis. Influencing factors of postoperative alignment and stereopsis were analyzed with a chi-squared test a...

We compare the surgical outcomes of intermittent exotropia of the basic, pseudo-divergence excess (pseudo-DE) and true divergence excess (true DE) types. A study was performed with 342 patients who had undergone surgery for intermittent exotropia of the basic, pseudo-DE or true DE type with a postoperative follow-up period of 6 months or more. The main outcome measures were postoperative angles of deviation at distance and near, and surgical success rates. Surgical success was defined as alignme...
