cyclotorsion
Cyclotorsion is the rotation of the eye about its visual axis, a torsional movement of the globe that can change the orientation of ocular structures such as the cornea and iris. In ophthalmology and vision science, it refers to the angular displacement of the eye around the line of sight, which can affect how refractive errors present to the retina.
It can occur during fixation, with rapid eye movements, or as part of the vestibulo-ocular reflex when
Clinically, cyclotorsion is most relevant in precision procedures that depend on stable axis orientation, such as
Measurement and assessment techniques include tracking iris landmarks or Purkinje images, corneal topography and keratometry performed
In sum, cyclotorsion describes a physiologic and clinically important eye rotation around the visual axis, with
