Subjective
Self-report and symptom scales can be biased by insight, motivation, distress, or under-reporting.
Objective neurocognitive measurement
The Digital Vital Sign for Brain Health.
RetinaTek turns eye movements, pupil dynamics, manual responses, and stimulus timing into objective measures of cognitive function, readiness, and recovery.
Built on more than a decade of military-backed neurocognitive research, RETINA is designed to reveal subtle changes in performance that conventional screens and self-report can miss.
The measurement gap
Cognition is still measured with tools that are too subjective, too slow, and too insensitive.
Brain health decisions often rely on symptom checklists, coarse cognitive screens, and lengthy test batteries. These tools can miss subtle impairment, be difficult to repeat longitudinally, and struggle to separate true neurocognitive change from effort, mood, age, education, or motor-response confounds.
Insensitive
Conventional measures may miss subtle deficits, compensation, or early change.
Hard to repeat
Traditional testing can be too burdensome for frequent monitoring, recovery tracking, or scalable deployment.
The RETINA approach
A cognitive stress test built from synchronized signals.
RETINA presents structured visual and cognitive tasks while capturing synchronized eye movements, pupil dynamics, manual responses, and stimulus-event timing. By measuring how the brain controls gaze, attention, inhibition, and reaction time under cognitive load, RETINA generates objective neurocognitive markers in minutes.
Cue
Controlled stimuli probe attention, inhibition, speed, and working memory.
Capture
Eye movements, pupil dynamics, manual responses, blinks, and timing data are synchronized.
Compute
Trial-level data are transformed into interpretable neurocognitive metrics.
Report
Outputs support review of readiness, recovery, performance, and longitudinal change.
What RETINA measures
Eye Movements
Saccadic latency, response variability, inhibition, distractibility, and visual attention.
Pupil Dynamics
Cognitive load, alertness, arousal, effort, and autonomic modulation where hardware supports collection.
Manual Responses
Reaction time, accuracy, and overt task performance.
Composite Scores
Cognitive Readiness, Speed, and Cognitive Control.
Scientific foundation
Validated across military-backed neurocognitive research.
RETINA builds on peer-reviewed research across visual attention, traumatic brain injury, concussion, cognitive load, performance validity, and military neurocognitive screening.
10+ years
Military-backed validation
Developed through years of federally supported neurocognitive research in military and clinical populations.
Multimodal
Eye + pupil + response timing
Combines task-evoked eye movements, pupillometry, manual responses, and stimulus timing.
MRI-linked
White matter correlation
RETINA-related metrics have been associated with DTI indicators of white matter disruption in military TBI research.
VR-ready
Portable deployment
Modern headset-based prototypes support scalable, controlled, repeatable testing environments.
Where objective cognitive measurement matters
Built for repeated measurement where cognitive decisions matter.
Research & Clinical Trials
Objective neurocognitive endpoints for studies of attention, recovery, treatment response, and cognitive change.
Concussion & Recovery
A planned clinical-development pathway for objective adjunctive assessment and longitudinal recovery tracking.
Rehabilitation
Repeatable measurement to support recovery trajectory, load tolerance, and treatment-response research.
Defense & Human Performance
Cognitive readiness metrics for high-stakes environments where speed, control, and consistency matter.
Executive Health
Non-diagnostic cognitive performance tracking for longitudinal brain health and premium prevention-oriented care.
Platform vision
The first wedge is concussion. The larger opportunity is objective cognition.
RetinaTek's long-term vision is to make cognitive function measurable with the same repeatability and objectivity that modern medicine expects from other physiological systems. The platform begins with controlled, opt-in, task-based sessions and expands through research, clinical development, human performance, and longitudinal brain health applications.
