Purpose The aim of this study was to evaluate the medial rectus plication (MRP) procedure in management of basic intermittent exotropia (XT) regarding efficacy, surgical outcome, and complications. Patients and methods This is a retrospective case series study that included 22 patients, aged 4–50 years, with basic type intermittent XT ranging from 25 to 40 prism diopters (PD) (mean=35.2±5.2 PD), with pure horizontal muscle imbalance. Bilateral MRP (fornix-based incision) was performed in all patients. The follow-up visits were scheduled in the first week and at 1, 3, and 6 months, postoperatively. The patients’ data were collected from Abo Elriesh Pediatric Hospital and Kasr El Ainy Teaching Hospital, Faculty of Medicine, Cairo University, Cairo, Egypt. Success was defined as orthophoria or small angle XT less than 10 PD or esotropia (ET) of 4 PD or less. Results The mean age of the patients at the time of surgery was 15.6±11.2 years. No intraoperative complications were recorded in any patient. One week postoperatively, 13 (59%) cases were successful, two (9%) showed ET, and seven (32%) had XT more than 10 PD. One, 3, and 6 months after surgery, 14 (64%) patients were orthophoric, seven (32%) showed XT more than 10 PD, and one (4%) patient showed ET. Conclusion Bilateral MRP was effective in the treatment of basic type intermittent XT. It is a relatively quick, simple, and safe procedure with a fair success rate and minimal postoperative side effects. In addition, it is a reversible procedure.
