Over 200 neurological issues express themselves in eye and head movements, including concussion/mTBI, vestibular/balance problems, and even neurodegenerative disorders. The potential of eye and head movement analysis is unlocked with InSight, Saccade Analytics' cutting-edge software solution that provides objective, reliable, and accurate metrics on brain function. It starts with a 5-minute set of tests in virtual reality, which measure how the patient's eyes and head respond to basic tasks. Our software, based on 30 years of research at McGill University, generates a diagnostic report of metrics specific to various key neurological systems.
