Tiny muscles control the movements of the eyeballs. The inferior oblique is a thin narrow muscle that extends along the inner side of the eyeball. It helps move the |eye| sideways and rotates it slightly. The inferior oblique muscle works in conjunction with the other |eye| muscles to move the |eye|. These muscles are anchored to the sclera near the cornea. The |brain| sends messages to the muscles, causing them to move both eyes in the same direction at once. When there is an imbalance in strength of these muscles, a person may appear cross-eyed, or wall-eyed.
