Non-TBI Trauma

Accurate and non-invasive methods for objectively identifying and monitoring head injuries (such as a concussion) are still an unmet need. It is known that pupil constriction in response to light stimuli can reflect changes in neural activity in the brain and is associated with sleep disturbances. The investigators aim to examine the feasibility of using virtual reality goggles for monitoring traumatic brain injury by analyzing the pupillary response to multifocal chromatic stimuli. The VR device was programmed to present brief, low-intensity light stimuli (without glare), while the headset's camera records the pupil's reaction.
