The medial rectus muscle is a muscle in the orbit.

As with most of the muscles of the orbit, it is innervated by the inferior division of the oculomotor nerve (Cranial Nerve III).

This muscle shares an origin with several other extrinsic eye muscles, the anulus tendineus, or common tendon.

It is the largest of the extraocular muscles and its only action is adduction of the eyeball. Its function is to bring the pupil closer to the midline of the body. It is tested clinically by asking the patient to look medially.

Comparison of bilateral medial rectus plication and resection for the treatment of convergence insufficiency-type intermittent exotropia.

Wang X, Zhang W, Chen B, Liao M, Liu L.
Acta ophthalmologica. 2019 May;97(3)e448-e453.
To compare the clinical outcomes of bilateral medial rectus plication and resection for the treatment of convergence insufficiency (CI)-type intermittent exotropia (IXT). Fifty-five patients with CI-type IXT were included in this prospective study and were followed for 6 months. The patients were r

An Analysis of Extraocular Muscle Forces in the Piked Dogfish (Squalus acanthias).

Gurley M, Motta P.
Anatomical record (Hoboken, N.J. : 2007). 2019 May;302(5)837-844.
Vertebrates utilize six extraocular muscles that attach to a tough, protective sclera to rotate the eye. The goal of the study was to describe the maximum tetanic forces, as well as the torques produced by the six extraocular muscles of the piked dogfish Squalus acanthias to understand the forces ex

The intramuscular nerve distribution in the extraocular muscles may be crucial for understanding their physiological and pathological responses. This study aimed to determine the oculomotor nerve distribution in the medial rectus muscle (MR) using Sihler's staining. Thirty-seven MRs from 23 cadavers
