Comparison between lateral rectus plication and resection on residual esotropic patents

Purpose: To compare the surgical outcomes of lateral rectus plication and resection techniques in patients with residual esotropia. Methods: In this RCTstudy, a total of 57 patients with residual esotropia (31 females and 26 males) who were candidate for lateral rectus resection were included and randomized into plication (n=27) and resection (n=30) groups. The inclusion criteria were residual esotropia after uni- or bilateral medial rectus recession, or unilateral recession and resection (R&R). Subjects with a history of prematurity, lack of central fixation, extraocular muscle palsy, systemic, ocular disorders, follow up less than three months were excluded. A comprehensive ophthalmicexamination was conducted preoperatively and at 1, 3 and 6 month follow-ups. Surgical success rate was considered postoperative eso- or exotropia ≤10pd. Results: Postoperative success showed no statistically significant difference between these two groups at all postoperative follow- ups of months 1, 3 and 6 (postoperative success rate at month 6 was 77.3% in plication and 85.2% in resection group). There was also similarity between dose responses of these groups in uni- or bilateral operations,Conclusion: lateral rectus plication and resection had similar success rate results. Each surgical method could be selected according to surgeon s skill and comfort. We recommend plication method for patients with postoperative probability of anterior segment ischemia .
