Short-Term Changes of Immediate Postoperative Deviation after Lateral Rectus Recession for Intermittent Exotropia

Abstract

PURPOSE: To assess the prevalence of short-term changes in immediate postoperative deviation, and to evaluate the relationship of these to clinical factors after lateral rectus recession for intermittent exotropia.
METHODS
One hundred patients who had lateral rectus recession performed for intermittent exotropia and who had at least 3 months of postoperative follow-up were included in this study.
RESULTS
The average angle of esodeviation on postoperative day 1 was 8.2 (-5 ~ +25) delta. The rate of surgical success (or=10delta on postoperative day 1 showed a higher chance of surgical failure due to overcorrection at postoperative 3 months (p=0.002). The preoperative deviating angle, type of exotropia, and combined oblique muscle surgery did not influence the outcome.
CONCLUSIONS
An esodeviation of 10 ~ 15delta on postoperative day 1 was related to a good outcome at postoperative 3 months. Less esodeviation and smaller exotropic drift occurred in patients aged 10 years and older, so it is possible that an initial overcorrection of >or=10delta may remain for a long period of time in the older patient group.
