Which term describes when both eyes rotate about the z axis to the right during versions?

• A. Levoversion
• B. Dextroversion
• C. Levocycloversion
• D. Dextrocycloversion

Answer: (B)

The main idea is that versions are conjugate eye movements, meaning both eyes move together in the same direction. When both eyes shift toward the patient’s right, that gaze is described as dextroversion. There is no torsional component specified here, so we refer to the simple horizontal conjugate movement to the right as dextroversion. If torsion were involved (rotation around the line of sight), we would use cycloversion, such as dextrocycloversion, to capture that extra twisting. The other terms would describe leftward movement or movements that include a twist, which isn’t indicated in the description.
