Cyclo-deviation Test Book
Cyclo-deviation or Torsional Displacement can result from imbalances of the eye muscles. The detection and calibration of this condition is important in ocular motility exams. Failure to detect this condition can seriously affect binocular vision and can cause a variety of symptoms from double vision to loss of depth perception discomfort and pain (called Asthenopia). The Awaya test for Cyclo-deviation provides an easily administered and repeatable method to test for near vision affects of this condition.
