Lateral Rectus Muscle Strangulation in Cases of Exotropia

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.

About this study

Under general anesthesia and after sterilization and draping of the eyes, an eye speculum is inserted. The muscle is exposed and hooked through either a fornix-based or limbal-based incision. Careful dissection is carried out to delineate the muscle edge, a previously measured blook of the lateral rectus muscle is sutured (strangulated) with proline 10/0 as in (fig-1). Patients will be followed-up next day after surgery then after 1 month and after 6 months.

Muscle strangulation

Procedure

lateral rectus muscle strangulation as a weakening technique in cases of exotropia.

Primary outcomes

  1. Correction of strabismus

    Time frame: 12 months

    the correction was done by lateral rectus muscle strangulation

Secondary outcomes
