Clinical analysis of childhood intermittent exotropia with surgical success at postoperative 2 years.
Acta Ophthalmologica 2016 March
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.
