The extraocular muscles, or extrinsic ocular muscles, are the seven extrinsic muscles of the eye in humans and other animals. [ 1] Six of the extraocular muscles, the four recti muscles, and the superior and inferior oblique muscles, control movement of the eye. The other muscle, the levator palpebrae superioris, controls eyelid elevation.

[ 2] The eye that is pointed at an object can alternate. [ 3] The condition may be present occasionally or constantly.

It can occur as an overall difference between the two eyes, or as a difference in a particular meridian. [ 1] If the ocular image size in both eyes are equal, the condition is known as iseikonia. [ 2]
