Subjects and Methods
The medical records of 107 consecutive patients, 59 females and 48 males, who had undergone surgery for basic intermittent exotropia between June 1995 and July 2004 were retrospectively reviewed. The inclusion criteria were as follows: (1) intermittent exotropia; (2) “basic” type (the near deviation was within 10Δ of the distance deviation); (3) an absence of lateral incomitance of more than 10Δ; (4) patient over 4 years of age; (5) amblyopia; (6) no simultaneous oblique surgery; (7) no history
Results
Table 2 shows the characteristics of the conventional surgery and augmented surgery groups. There were no significant differences between the mean alignment, the follow-up period, or the age of the patients who had undergone either of the two surgical procedures (p = 0.23, p = 0.55, p = 0.06). The range of the follow-up period for patients who had conventional and augmented surgery was 6 to 39 months and 6 to 35 months, respectively.
On postoperative day 1, the success rate was 70.7% in those
Discussion
In the surgical management of exotropia, there is widespread agreement that an initial overcorrection is needed because there is a tendency toward a postoperative exotropic drift. Raab and Parks9 reported that an overcorrection of 10Δ to 20Δ provided the best outcome. Scott et al10 advised an overcorrection of between 4Δ and 14Δ. Moreover, good correlations between the initial and final measurements after surgery for intermittent exotropia have been reported by others.11, 12 In this study,
