Abstract

ABSTRACT: A 79-year-old woman suffered ocular trauma from an umbrella. Exotropia of the left eye was observed, and the left eye could not adduct to the midline. Both edges of the lacerated medial rectus were sutured together with the aid of preoperative computed tomography (CT), which showed posterior muscle belly widening due to posterior slippage toward the equator. The alignment and ocular movement were improved postoperatively. Repairing a lacerated medial rectus is difficult because its edge slips into the muscle cone posteriorly. Preoperative CT was useful in identifying the posterior portion of the lacerated muscle, enabling successful repair.
