What the study is about

This study is investigating whether eye exercises for abducens palsy and internuclear ophthalmoplegia increase ocular range of motion in the paretic direction when performed in virtual reality under head-cancelled compared to head-active conditions.

Being studied: Head-cancelled virtual reality

Conditions: Internuclear Ophthalmoplegia; Palsy, Abducens

OCNP Group Exclusion Criteria

  • Presence of bilateral OCNP
  • Range of motion better than 50%
  • Visual acuity worse than 20/100 in either eye
  • Greater than 4-line difference in visual acuity between the eyes,
  • Structural anomalies or sensory sensitivities (e.g. visual motion sensitivity) that would prevent them from wearing or tolerating a VR headset

Participants will be excluded if they are unable to participate if inclusion criteria are not met.
