Internuclear Ophthalmoplegia Clinical Trial
Official title:
Head-Cancelled Virtual Reality for Rehabilitation of Ocular Cranial Nerve Palsies
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.
Participants with abducens palsy or internuclear ophthalmoplegia, two common types of ocular cranial nerve palsies, will perform 3 different tasks in virtual reality under head-cancelled and head-active conditions. Head active is the normal state, where gaze can be shifted by moving the head, the eyes, or a combination of the two. Head-cancelled refers to the condition where the scene moves with the head, rendering head movement ineffective to shift gaze. In this condition, the eyes must move in order to shift gaze. The hypothesis is that this requirement for eye movement will result in larger eye movements, which could be therapeutic. The tasks performed under the two conditions will include horizontal transposition of coins, repetitive horizontal saccades, and game play. The primary analysis will be a within subject's comparison of eye movement amplitude in head-cancelled (experimental) versus head-active (control) conditions. Additionally, as a control comparison for secondary analysis, a group with normal vision will also perform the tasks under both conditions. ;
