intorsion

intorsion /in·tor·sion/ (-tor´shun) inward rotation of the upper pole of the vertical meridian of each eye toward the midline of the face.

in·tor·sion (

n-tôr

1. The inward rotation of a limb or an organ.

2. The inward convergent rotation of the upper pole of the vertical meridian of each eye. Also called conclination, negative declination.

intorsion [in-tor´shun]

tilting of the upper part of the vertical meridian of the eye toward the midline of the face.

torsion

Rotation of an eye about an anteroposterior axis. If the upper pole of the vertical meridian of the cornea appears to rotate inward, it is called intorsion, and outward, extorsion. If the eye rotates to the right it may be called dextrotorsion and if it rotates to the left it may be called laevotorsion. It may occur as a result of a head tilt, extraocular muscle weakness or rotation of the eye to a tertiary position. Syn. cycloductin; cyclorotation; torsional movement. See Donder's law; tertiary position; incongruous hemianopia.
