Brief Summary
The goal of our study to evaluate effect of lateral rectus muscle strangulation as a novel effective weakening technique in cases of exotropia. It is a case-series intervensional study with a total 12 participant who are diagnosed as exophoria or intermittent exotropia who are older than 4 years old. All patients will be assessed regarding their angle of deviation and then undergo lateral rectus muscle strangulation under general anesthesia and then will be followed- up at 1st day, 1st week, 1st month and 6th months.
