“…Chia et al 14 reported that age at surgery and preoperative angle of deviation are not prognostic factors for the success of surgery. Gezer et al 13 reported that age at surgery is not a prognostic factor for the success of surgery, but preoperative degree of deviation, the amount of correction by surgery, and preoperative refractory error are prognostic factors. Roh et al 20 also suggested that age at surgery is not associated with the success of surgery, and stereopsis is the only prognostic factor for the success of surgery.…”

“…However, not only age but dysfunction of binocular fusional ability and degree of deviation should also be considered as predictors of surgical outcomes. 23 Gezer et al 13 reported that a preoperative exodeviation of 40 PD or more had a significantly greater likelihood of recurrence because of a positive correlation between preoperative and postoperative deviations. Similarly, Scott et al 25 reported that the degree of preoperative exodeviation, patient age at surgery, status of refraction, degree of anisometropia, and difference in the angle of deviation at the distance between upward gaze and downward gaze were prognostic factors.…”

“….3%), the exact prediction of the surgical outcome is difficult. 8,[10][11][12] There have been a number of reports of possible prognostic factors affecting surgical outcomes, such as preoperative degree of exodeviation, 13 duration of postoperative follow-up, 7 surgical procedures, 12,14 types of exotropia, 10,11,15 and stereopsis. 16 However, controversies still abound.…”

“…In particular, the age at surgery is subject to dispute because some studies advocated surgery at an early age, [17][18][19] whereas others claimed that early surgery is not desirable. 8 Although many reports 9,13,14,20 have stated that age at surgery for intermittent exotropia does not affect the surgical outcome, there are some reports 8,17,18 identifying age as a prognostic factor. Thus, referring to age as a prognostic factor is debatable.…”

Purpose To evaluate the prognostic factors, particularly age at the time of surgery, for recurrence after unilateral medial rectus resection and lateral rectus recession (R&R) procedures in patients with intermittent exotropia, or X(T). Methods Medical records of 489 subjects who received unilateral R&R procedures with more than 12 months of follow-up were reviewed. The patients' surgical outcomes with a deviation of less than 10 prism diopters (PD) of exotropia and less than 5 PD of esotropia were defined as a success. Outcomes with more than 11 PD of exotropia were designated as recurrences, and those with esotropia of more than 5 PD after 3 months of operation were noted as overcorrection. The prognostic factors for recurrence were analyzed by the multivariate logistic regression test. Results Of the 489 subjects, 209 had successful surgical outcomes and 280 had recurrences, whereas overcorrection was not found. Mean age at operation was 8.9 ± 6.5 years, mean preoperative distant X(T) size was 32.9 ± 6.0 PD, and mean follow-up period was 27.5 ± 17.9 months. On the basis of the survival analysis in which survival represented time of recurrence, the mean duration was 31.2±1.7months. Age at onset, age at surgery, and immediate postoperative alignment proved to be significant factors influencing a favorable outcome by multivariate logistic regression analysis (Po0.05). However, gender, family history, and preoperative deviation size were not significantly predictive of success (P40.05). ConclusionIn unilateral R&R procedures, increasing patient age at the time of surgery was associated with lower recurrence rates. Recurrence rates also increased with the immediate postoperative angle and with the postoperative angle of deviation at 1, 3, 6, and 12 months.
