Tiny muscles control the movements of the eyeballs. The rectus lateralis muscle pulls the |eye| to the outside. It 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.
