Eye movements, measured on a smartphone
Assessing eye movements has long been part of the clinical concussion examination, but manual methods can be subjective and hard to repeat consistently.
BrainEye is a smartphone app that records eye-movement and pupil measurements in about a minute. Neuroglance uses it to give the treating healthcare professional consistent, objective measurement information to support their clinical assessment.

The technology behind BrainEye
Smartphone
The BrainEye app uses a smartphone's camera to record the athlete's eye movements.
Baseline
A baseline test is recorded when the athlete is well, giving the treating clinician a personal reference point.
Repeat testing
Tests can be repeated after a suspected concussion and at follow-up visits, giving the clinician additional measurement information.
Extract & Upload
Eye-movement measurements are extracted and securely uploaded to the BrainEye cloud.
Clinician review
Results are made available in a report for the treating healthcare professional to review as part of their clinical assessment.
Big Data & AI
Accumulated test data supports the ongoing development of BrainEye's machine learning models.
Capture and calibrate
The BrainEye app guides the user through calibration and a short series of simple eye tests, such as following a moving dot.
Using the phone's camera, the app captures images of the pupils and irises and records eye-movement measurements for the treating healthcare professional to review.
Instant results of test
The results of each individual test are uploaded to the BrainEye cloud. The user is provided with a summary of their results. These are immediately compared to previous tests.
Eye movements and concussion
Smooth pursuit, the ability to follow a moving target smoothly with the eyes, relies on brain networks that span the visual pathways, brainstem, cerebellum and several regions of the cortex.
Published research has reported that after a concussion, smooth pursuit eye movements may lag behind a moving target, become less coordinated between the two eyes, start more slowly, or be interrupted by catch-up saccades.
This is why eye-movement assessment forms part of the clinical concussion examination, and why consistent measurement can be useful to the treating clinician.
Intended use
BrainEye is intended for individuals aged 13 to 60 who take part in sport, sports training or exercise-related activities, under specified assessment conditions. Results are provided to a healthcare professional as supplementary measurement information to support their clinical assessment of suspected or confirmed sports-related concussion.
Important: BrainEye does not diagnose, detect, confirm or exclude concussion or any other condition; does not determine severity, cause or prognosis; does not compare results to normative or reference population data; does not classify results as normal or abnormal; and does not indicate recovery status or readiness to return to play. It is not a substitute for clinical assessment and must not be the sole basis for any clinical decision.
BrainEye is supported by ongoing published research, including a 2025 study with professional Australian football players: Clough et al., Sports Medicine – Open (2025).
