Which term describes a binocular movement where both eyes rotate about the z axis to the left during versions?

Explanation:
Levoversion is a conjugate binocular gaze to the left, where both eyes rotate together in the same direction without an accompanying torsional (cyclo) component. When the movement is described as turning the eyes to the left during versions, the appropriate term is levoversion, since the gaze is horizontal and synchronized between the two eyes. If there were a torsional component accompanying the leftward gaze, the correct term would shift to levocycloversion.
