Leads groundbreaking effort to monitor youth concussions How does pupillometry work? Ongoing research will determine whether pupillometry might provide early warning for doctors to provide lifesaving interventions after concussions and other traumatic brain injuries. Our intensive care unit (ICU) uses the device on every patient after brain surgery and every patient with stroke, hemorrhage, or severe concussion/injury. Today, UT Southwestern houses the world’s largest database for pupillometer research in acute brain injury. Pupil changes were detectable up to eight hours earlier than traditional methods of assessment this early warning might grant us hours instead of minutes to intervene and reduce the risk of long-term brain deficits and cognitive loss.
We already know that the NeurOptics NPiⓇ-200 Pupillometer device can give doctors an early warning about insufficient blood flow to a patient’s brain (cerebral ischemia), as well as brain swelling and other severe issues that can develop in the days after a hemorrhagic stroke.ĭata from a UT Southwestern study of 56 patients showed that the pupils changed in seven of the 12 patients who developed cerebral ischemia after such a stroke.
In the quest for improved concussion care, a simple but advanced tool could give us hours of advance notice in diagnosing concussion and the complications that could arise in the days after the injury – all at the push of a button.
