A newly discovered technology helps track eye movement to identify concussions after head injury. The technology also helps determine the severity of the concussions and would mean more lives saved and less money spent. The study behind this technology was published in the journal Neurotrauma.
The new technology is very similar to what a doctor does when first examining a patient who has sustained a head injury. Doctor move a finger in front of the patient’s eyes to notice any peculiarities in the movement of the eyes, but now all that is automatized and much more precise.
Dr. Uzma Samandi, from NYU Langone Medical Center in New York City, NY is the woman behind this new technology. She stated that the results obtained with this new method are much more reliable than the follow my finger method because:
Each doctor is going to have variability in how well they’re going to be able to assess how well a person is getting better.
Samandi’s reasons for developing this new technology that helps track eye movement to identify concussions are quite simple: she said she simply needed a much more reliable way to assess concussions than what was available to her and the medical world.
A more accurate diagnosis will improve patients’ care and will allow safer recommendations for when the patients could return to work or do various things, such as swimming or running.
A concussion is defined by the Centers for Disease Control and Prevention as a type of brain injury that is caused by a blow, a bump or jolt to the head that has the ability to alter the way a brain normally functions.
Samandi’s study involved 75 people who had been in accidents and 64 healthy volunteers. All people watched a short video while the movements of their eye were tracked by a computer that was taught to recognize disconjugated eye movement. This type of eye movement is the most often eye movement abnormality that has been connected to brain injuries.
The results of the study revealed that people who had suffered trauma to the head could control their eye movements less than the people who did not have head injuries.
This new technology is available in research settings but there are high hopes that the FDA clears it for use by the end of 2015.
