Comparison of the Results of Plication and Resection Techniques in Horizontal Strabismus Surgery

INTRODUCTION: The aim of this study is to compare the results of plication and resection techniques in patients who underwent horizontal strabismus surgery.
METHODS: The records of patients who were operated due to horizontal strabismus in the Department of Ophthalmology of Health Sciences University Haydarpaşa Numune Training and Research Hospital between 2011 and 2017, were reviewed retrospectively. Those who underwent resection and those who underwent plication were divided into two groups. The amount of deviation at postoperative 1st day, 1st month and at the last control visit, were compared. Postoperative ≤ 8 PD deviation was considered successful.
RESULTS: Twenty-two patients underwent horizontal rectus plication combined with antagonist muscle recession surgery. Eight of the patients were operated for esotropia and 14 for exotropia, and their mean age was 14.59±10.27 years. Twenty-four patients underwent horizontal rectus resection combined with antagonist muscle recession surgery. Nine of the patients were operated for esotropia and 15 for exotropia, and their mean age was 19.67±13.38 years. The mean amount of preoperative deviation was 30.79±7.29 PD in the plication group, and 39.89 ±10.72 PD in the resection group. Mean follow-up time was 12.82±7.47 months in the plication group and 9.75±8.63 months in the resection group. There was no statistically significant difference between the success rates of the two groups according to their final control follow-up (p>0.05).
DISCUSSION AND CONCLUSION: Plication surgery, which is a fast, easy-to-apply and safe muscle strengthening technique, is as effective as resection surgery in the treatment of horizontal strabismus.
