version 

Conjugate movements of the two eyes in the same direction, such as dextroversion, both eyes rotate to the right; laevoversion (levoversion), both eyes rotate to the left; supraversion (sursumversion), both eyes rotate upward; infraversion (deorsumversion), both eyes rotate downward: these versions bring the eyes into the secondary positions of gaze. Movements of the eyes up and to the right are called dextroelevation, up and to the left, laevoelevation, down and to the right, dextrodepression and down and to the left, laevodepression: these versions bring the eye into the tertiary positions of gaze. Version eye movements are performed by yoke muscles (Fig. V2). Syn. conjugate eye movements. See conjugate deviation; cardinal positions of gaze; motility test." >Fig. V2 Version movements of the eyes from A to B
