Management believes that vision restoration works by stimulating the brain to heal itself through a process called neuroplasticity. Vision loss following a stroke or a traumatic brain injury stems from damage to the brain. Stimulating the brain in consistent, precise ways can help it to reorganize and heal, leading to partial or full recovery of vision.
Given the complexity of the brain and that the study of neuroplasticity is in its infancy, some questions were originally raised that vision restoration was occurring through eye movements instead of through self-repair in the brain.
A study conducted using an eye tracker, which monitors eye movement, showed that patients keep their eyes within 2 degrees to either side of the central fixation point 99 percent of the time.1
Other evidence that VRT is not attributed to eye movement is a study conducted at Columbia University that used an fMRI which shows changes in brain activity after VRT suggesting cerebral reorganization.2
