Comparison of Medial Rectus Resection and Plication in Exotropic Patients

Comparison of Medial Rectus Resection and Plication in Exotropic Patients

Purpose: To determine the surgical outcomes of the plication technique in comparison with the resection method on exotropic patients.

Methods: In this randomized clinical trial, a total of 52 exotropic patients (female, 51.9%) who are candidate for medial rectus strengthening will be randomly classified into plication (n=24) and resection (n=28) groups. The comprehensive visual and ocular examinations will be performed on all study subjects and they will be followed- up for three months postoperatively. Plication technique is the same as resection up to muscle suturing, in the next step, the sutures are passed through 2 scleral bites at 1 mm anterior to the muscle insertion, then the muscle was folded toward inside or outside by pulling and joining the sutures.

Inclusion Criteria:

Patients with a residual exotropia and history of uni- or bilateral lateral rectus recession or recession and resection (R &R) and those exotropic patients who were going to have already recession and resection (R & R) operation due to unilateral constant exotropia will be considered as eligible cases to be included.

Exclusion Criteria:

Subjects with a history of prematurity, intellectual disability, lack of central fixation (nystagmus, eccentric fixation, retinopathy of prematurity) subjects with systemic or other ocular diseases, neurological disorders, uncooperative patients and participants with less than three-month postoperative follow-up will be excluded from this study.
