Researchers at NYO Langone Medical Center have developed "eye-tracking" technology that is the most advanced way to detect the severity of brain injuries.  Concussions are a very common occurrence for people of all ages, ranging from mild to very severe traumatic brain injuries.  To date, science has lacked the proper diagnostic tools to really understand how severe each patient's concussion may be.  CT scans and MRIs do not show the damage to the brain after such an injury and doctors have been unable to determine whether a patient is at a higher risk of serious consequences after suffering a concussion.  The eye-tracking technology is the first step toward quantifying severity of concussions and the likely recovery time necessary for the patient to regain full brain function.  Patients were studied by tracking their ability to coordinate eye movement while watching a music video; patients with any type of brain injury were unable to property coordinate, while patients with injuries to body parts other than their brain had no problem with eye coordination.  This advance will push researchers to look further into how to more accurately measure eye movement and coordination to select which patients need careful medical attention after a brain injury.
