Diagnosis of mTBI in an ER Setting Using Eye-Tracking and Virtual Reality Technology: An Exploratory Study.

Area of Science:

• Neurology
• Biomarkers
• Medical Technology

Background:

• Mild traumatic brain injury (mTBI) diagnosis in emergency rooms (ER) requires efficient and accurate tools.
• Point-of-care biomarkers are being explored for rapid mTBI detection.
• Eye-Tracking and Virtual Reality (ET/VR) technology offers a novel approach to mTBI assessment.

Purpose of the Study:

• To systematically explore ET/VR technology as a diagnostic tool for mTBI in an ER setting.
• To evaluate ET/VR biomarkers for detecting and excluding mTBI in acute trauma patients.
• To assess the feasibility and accuracy of ET/VR in a clinical ER environment.

Main Methods:

• An explorative, prospective, single-arm accuracy study was conducted in two German trauma centers.
• Patients presenting to the ER with suspected mTBI within 24 hours of head trauma were examined using ET/VR glasses.
• Diagnosis of mTBI was established by blinded clinical experts based on comprehensive clinical, neurological, and imaging findings.

Main Results:

• ET/VR glasses were generally well-tolerated by patients.
• Out of 52 analyzed parameters, only two showed statistical distinction from random chance.
• No significant differences in oculomotor function were observed between mTBI and non-TBI subgroups, and no correlations with mTBI detection were found.

Conclusions:

• The current application of VR goggles for mTBI diagnosis in the ER setting is not recommended.
• Further research is needed to identify specific ET/VR parameters that can reliably diagnose mTBI.
• ET/VR technology, in its current form, does not provide sufficient diagnostic accuracy for mTBI in the emergency department.
