Assessment Battery Overview

By combining assessments, clinicians can collect objective data to make better-informed decisions about the nature of impairment and the corresponding treatment needed to optimize recovery.

EYE-SYNC® Smooth Pursuit

FDA-cleared eye tracking assessment to view, record and analyze impairment, EYE-SYNC® is supported by 15 years of clinical research.


SyncThink’s Vestibulo-Ocular Reflex (VOR) assessment provides clinicians with an objective assessment of vestibulo-ocular function while the patient is in motion.

EYE-SYNC® Saccade

SyncThink’s Saccade assessment provides clinicians with an objective assessment of fixation quality while the patient’s eyes move either laterally or vertically to specified points in a rapid succession.


SyncThink’s Vestibulo-Ocular Reflex Cancellation (VORx) assessment provides clinicians with an objective assessment of vestibulo-ocular function while the patient is in motion, set against a Virtual Reality (VR) environment.


Formed from the 2017 Berlin consensus guidelines, the Sport Concussion Assessment Tool Version 5 (SCAT5) is a commonly used clinical assessment to assist clinicians in the evaluation of brain health.


The Balance Error Scoring System (BESS) is a commonly used clinical evaluation method for measuring static  postural stability.

Simple Reaction Time

Simple Reaction Time is a tablet-based assessment to determine how rapidly a subject can react to a stimulus.

EYE-SYNC® Full Battery

SyncThink’s Full Battery is a combined assessment feature that allows clinicians to run EYE-SYNC® Smooth Pursuit, Saccade and VOR consecutively in under two minutes.

Platform Capabilities


Assessment Direction Test Length
Smooth Pursuit Clockwise, counter clockwise <60 seconds
Saccade Horizontal and vertical <60 seconds
Vestibulo-Ocular Reflex (VOR)  Horizontal and vertical <60 seconds
Vestibulo-Ocular Reflex Cancellation (VORx)  Horizontal (easy to difficult) <60 seconds
Full Battery Clockwise, horizontal <2 minutes

The SyncThink platform offers an array of objective assessments, in a mobile environment, which can be used to detect visual impairments. Using a logical flow, a clinician can choose to complete tests particularly relevant to the patient history, or conduct battery of assessments consecutively in minutes. Results collected then can be used to support the clinicians decision making process as well as their diagnosis and treatment plan.


Recovery Feature System Trained Duration
Saccade High velocity horizontal eye movements 15 sec intervals, random
Saccade  High velocity vertical eye movements 15 sec intervals, random
Vestibular Ocular Reflex (VOR) Fixation during horizontal head motion Variable, metronome
Vestiular Ocular Reflex (VOR) Fixation during vertical head motion Variable, metronome

During the recovery phase, visual training may be recommended as a means of therapy. As the patient improves, the clinician can use objective information to measure progress and consider further progressions. By using the SyncThink platform, clinicians can choose to dial back or accelerate visual training as they monitor symptoms, the patient response to stress, and the overall effectiveness of their interventions.


Dynamic Vision Focus Paradigm Direction
Smooth Pursuit Real Time Feedback (color) Clockwise
Smooth Pursuit Real Time Feedback (color) Counter clockwise
VOR Real Time Feedback (color) Horizontal fixation
VOR Real Time Feedback (color) Vertical fixation
Coming Soon! Speed based training Clockwise, counter clockwise

The performance applications on the SyncThink platform are designed to improve dynamic vision, a key characteristic of high level brain performance. By using real time feedback paradigms for training, the patient can receive instant feedback into how they are performing during the task. This is done by changing the color of the visual target as an indicator of high or low performance. 

Using these paradigms can prepare athletes, soldiers and patients to improve focus during tasks that require precise visual acuity and performance over time.

User testimonial: Massachusetts General Hospital

“This technology continues to impact how I evaluate and manage athletes and service members. Results of eye tracking have helped facilitate the most appropriate avenue for directing rehab after an athlete has sustained an injury.  When testing is normal, I feel more confident in gearing rehab toward other contributing systems like impairments coming from the vestibular system or the neck.”

User testimonial: Washington Township Medical Foundation

“Over the last year, our use of the compact, portable, VR device has resulted in a paradigm shift in my care. Whether on the sidelines or in the clinic, the fact that we can now assess and serially track the best direction for treatment in an easy-to-perform 1-minute test, has been simply game changing.”

User testimonial: Stanford University Sports Medicine

“EYE-SYNC is a pivotal tool for clinical decision-making and management of my patients. It provides real-time data to quantify things I am seeing during my assessment, as well as capturing the minute details not visible with the naked eye. EYE-SYNC also allows me to track progress over time, which not only ensures I am providing the correct treatment algorithm, but also improves my patients’ confidence in their recovery and ultimately return to sport. In a world where we are constantly discovering more about the complexities of head injury, clinical objective metrics are imperative to an otherwise subjective pathology.”

Frequently Asked Questions (FAQ's)

  • What is the SyncThink platform?

    The SyncThink platform is a Virtual Reality (VR) based eye tracking system that can assess brain health and improve visual performance. We provide a battery of assessments that can be used to rapidly detect visual impairments occurring with the ocularmotor and oculo-vestibular systems. Once these impairments are identified, trained clinicians can use various paradigms for monitoring improvement over time or to provide visual training to improve dynamic vision.

  • How has EYE-SYNC been validated?

    EYE-SYNC is the proprietary analysis metrics used to quantify and objectively determine a patient’s visual performance. Developed over a 15-year period of rigorous scientific research in collaboration with the US Department of Defense and the Brain Trauma Foundation, EYE-SYNC’s clinical utility has been extensively documented in dozens of publications. In 2016, the FDA cleared EYE-SYNC for viewing, recording, and analyzing eye movements in support of visual impairment identification. In 2019, the FDA selected EYE-SYNC as Breakthrough Device Designation for aid to concussion assessment.

  • What value does EYE-SYNC add to my practice or clinical business?
