Portable VR-based Chromatic Pupilloperimeter for Diagnosis and Monitoring of Traumatic Brain Injury
An observational study of Traumatic Brain Injury (TBI) Patients and Healthy Participants, run by Sheba Medical Center at 1 site in Israel.
Trial summary
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. Read more about this study

About this study
Official title: Development of a Portable VR-based Chromatic Pupilloperimeter for Diagnosis and Monitoring of Traumatic Brain Injury
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.
Read the detailed description
Healthy adults, patients with combat-related mild to moderate TBI and age- and gender-similar soldiers without TBI (defined as war-related injury who screen negative for TBI based on symptoms, blood, and/or head CT) will be recruited as non-TBI trauma (NTT) controls.
All subjects will undergo: A complete ophthalmologic examination to exclude ocular pathologies, including intraocular pressure (Goldmann applanation tonometry), and slit lamp biomicroscopy of the anterior and posterior segments; Assessment of best corrected visual acuity (BCVA); Color vision test, and VR Chromatic Pupilloperimetry (VRCP) testing.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Virtual Reality pupillometry testDiagnostic test
A short (less than 10 minute) chromatic pupilloperimetry test administered via virtual reality (VR) goggles. Participants are exposed to brief, low-intensity chromatic light stimuli within the VR environment, designed to elicit pupillary responses without causing glare. Pupil size is monitored, enabling objective assessment of neural function and potential indicators of head trauma.
