Description of intervention(s) / exposure
Eye movements have been used for decades to interrogate neurological function, and we have an extensive understanding of the consequences of a broad range of neurological disorders on eye movements. BrainEye is a smartphone application that uses artificial intelligence (AI), machine learning, and cloud based technology to record and anlayse the location of the eye in space over time, with a view to providing a snapshot of neurological function in an individual over time.

In patients diagnosed with concussion or a mild traumatic brain injury, the BrainEye application will be used to record and measure (1) smooth pursuit eye movements (SMP) where a patient follows, with their eyes, a dot moving in a circle around the screen of their smartphone, and (2) the pupillary light reflex (PLR) where a patient looks at the back of the smartphone and the phone's own flash appears for 3 seconds to illuminate the eyes. These tests will take less than 5 minutes, including re-reading on-screen instructions if required.

Data will be collected at 4 timepoints: firstly within 24 hours of a post concussive event within the emergency department (ED) by an ED occupational therapist, and then 2, 7 and 30 days post event by the individual in his/her own home. Patients will be provided with SMS reminders to use the BrainEye application on days 2, 7 and 30.

Data will include measures of latency, velocity, amplitude and accuracy for SMP and PLR.

From these data BrainEye will determine a concussion algorithm that sensitively identifies and tracks recovery from concussion.

Diagnosis / Prognosis
Comparator / control treatment
Sensitivity and specificity will be determined by comparison with existing data in neurologically healthy individuals. These data have been collected in previous studies of healthy individuals over the past 12 months, specifically of studies conducted by Monash University researchers. These studies were granted approved by the Monash University Human Research Ethics Committee, as meeting the requirements of the National Statement on Ethical Conduct in Human Research.
