The presence or absence of centrifugal eye movement changes due to alterations in gravity perception will be verified by comparing tilted visual backgrounds presented via a HeadMounted Display that either induce or fail to induce gravity perception. This will allow for the quantification of the sense of dizziness at the spatial orientation level independent of peripheral vestibular function. Furthermore, we will investigate the potential for quantifying gravity perception function in patients with Persistent PosturalPerceptual Dizziness who complain of persistent unsteadiness resulting from increased visual dependence in spatial orientation formation.

Diagnosis
| Maneuver |
Research participants will wear VR goggles. Inside the goggles, backgrounds with defined verticality (such as buildings) and backgrounds without defined verticality (such as outer space) will be displayed. These backgrounds will be tilted, and the resulting torsional eye rotation angle (or ocular counter-roll) will be measured. The tilt angles will be 60, 90, 120degrees.The eye movements will be digitized and recorded in real-time.
