The following terms may be used to describe<unk> : * Incyclotorsion is a term applied to the inward, torsional (rotational)<unk>  of the<unk> , mediated by the superior oblique muscle of the<unk> . The superior oblique muscle is innervated by cranial nerve IV (trochlear nerve). Incyclotorsion may also be used to describe one part of the condition of the<unk>  when a patient has an oculomotor nerve palsy. The oculomotor nerve (cranial nerve III) supplies the inferior oblique muscle (along with four other<unk>  muscles – superior rectus, medial rectus, inferior rectus and the striated muscle of levator palpebrae superioris), and when this muscle is non-functional (as in oculomotor palsy) the<unk>  incyclotorts; i.e. twists/rotates inward. * Excyclotorsion is a term applied to the outward, torsional (rotational)<unk>  of the<unk> , mediated by the inferior oblique muscle of the<unk> . The inferior oblique muscle is innervated by cranial nerve III (oculomotor nerve). Excyclotorsion may also be used to describe the condition or state of the<unk>  when a patient has a cranial nerve IV (trochlear nerve) palsy. The trochlear nerve supplies the superior oblique muscle, and when this muscle is non-functional (as in trochlear palsy) the<unk>  excyclotorts; i.e. twists/rotates outward. This excyclotorsion may be corrected through surgery using the Harada-Ito procedure. * A version is an<unk>  involving both<unk> s moving synchronously and symmetrically in the same direction. Examples include: #Dextroversion / right gaze #Laevoversion / left gaze #Sursumversion / elevation / up gaze #Deorsumversion / depression / down gaze #Dextroelevation / gaze up and right #Dextrodepression / gaze down and right #Laevoelevation / gaze up and left #Laevodepression / gaze down and left #Dextrocycloversion – top of the<unk>  rotates to the right #Laevocycloversion – top of the<unk>  rotates to the left
