In patients presenting with a head injury*it is still often difficult to diag**se a concussion, CT scans being the standard tool used to get to the final answer. Yet, even CT scans do **t reveal a concussion every time. **w researchers at* NYU Langone Medical Center have presented a new eye Tracking technique that may one day become a standard part of performing a brain injury analysis in the emergency room or even on the sidelines of football fields.
Ab**rmal eye movement has been k**wn as a symptom of brain injury for a very long time, but objectively measuring its*severity and correlating it to the extent of brain injury has prevented the technique from reaching its true potential in clinical practice. Specifically, disconjugate eye movement, in which the eyes don’t move in synchrony, is the window into the brain. To measure it, the NYU team used high-accuracy Tracking cameras to follow the eyes of people watching a music video. They compared the eye movements of*64 healthy people against 75*trauma patients visiting New York’s Bellevue Hospital’s ER.
What the results showed is that*13 patients whose Concussions were confirmed with a CT and 39 whose CT scans were coming up **rmal displayed disconjugate eye movement. 23 others with injuries to other parts of the body than the head were **t directed to receive a CT and showed **rmal eye movement as in healthy folks. The researchers believe that eye Tracking “may help quantify the severity of ocular motility disruption associated with concussion and structural brain injury,” according to the study*in Journal of Neurotrauma
