Question

Quizplus · Accepted Answer

The medial rectus muscle is responsible for moving the eye inward towards the nose (adduction). When this muscle is overactive, it can cause the eye to turn inward (esotropia) or cross-eyed. Cutting this muscle can weaken its action, allowing the other muscle (lateral rectus) to pull the eye outward and align it with the other eye.
