Can Eye Tracking Help Assess the State of Consciousness in Non-Verbal Brain Injury Patients?

Developments in eye-tracking technology are opening up new possibilities for diagnosing patients in a state of minimal consciousness because they can provide information on visual behavior, and the movements of the eyeballs are correlated with the patients' level of consciousness. The purpose of this study was to provide validation of a tool, based on eye tracking by comparing the results obtained with the assessment obtained using the Coma Recovery Scale-Revised (CRS-R). The mul-ti-center clinical trial was conducted in Poland in 2022-2023.
