Evidence
RETINA builds on federally funded research across attention, cognitive load, performance validity, military TBI, MRI-linked biology, and headset-based deployment.
RetinaTek's technology was not created as a wellness gadget or generic eye-tracking demo. RETINA emerged from a long-running scientific program focused on objective, repeatable measurement of cognitive performance under controlled task demands. The studies summarized here support the RETINA platform and future clinical-development work; they are not current RT-Focus diagnostic or disease-monitoring claims.
The published science behind RETINA supports a layered evidence case: first establishing that task-evoked eye and response metrics index cognitive function, then showing sensitivity to impairment under load, performance-validity utility, biological plausibility, and deployment feasibility.
What the studies support
Task-evoked eye and manual response metrics can index attention, inhibition, processing speed, consistency, and cognitive control.
Why it matters
This separates RetinaTek from passive gaze tracking and simple reaction-time tasks.
What the studies support
Published RETINA-related studies have shown that cognitively demanding oculomotor tasks can reveal neurocognitive performance patterns associated with TBI history, injury severity, and recovery-related research measures.
Why it matters
The value is not just measuring whether someone can complete a task. It is measuring how efficiently the brain controls performance when demand increases.
What the studies support
Multimodal eye and manual response data can help identify low-effort, invalid, or non-interpretable performance patterns in published simulated-impairment research.
Why it matters
Confidence in cognitive assessment depends on knowing whether the result is usable and interpretable.
What the studies support
RETINA-related metrics have been associated with DTI white matter findings in military TBI research.
Why it matters
MRI-linked findings help connect task performance to brain biology and strengthen the rationale for future clinical-development work.
What the studies support
Head-mounted prototypes have demonstrated feasibility, tolerability, and favorable usability in military research settings.
Why it matters
The measurement approach is not trapped in a lab-grade eye tracker. It can move toward scalable deployment on commercial headset hardware.
74.7%
Published RETINA-related chronic mTBI research reported that a combination of multimodal assessment metrics distinguished military research participants with chronic mild TBI from controls with a 74.7% classification signal.
This is RETINA platform evidence from research settings. It does not constitute a current RT-Focus diagnostic, screening, or disease-monitoring claim.
AUC 0.99
Published simulated-impairment research found that embedded saccadic and manual response indices could classify best-effort versus simulated low-effort performance with very high accuracy.
This finding supports the value of multimodal data-integrity checks, not a guarantee that all invalid clinical performance can be detected.
DTI-linked
In military TBI research, RETINA-related task-evoked saccadic variability and working-memory-related metrics were associated with DTI white matter findings across distributed brain regions.
These associations support biological plausibility and future clinical-development rationale. They do not establish RT-Focus as a current imaging-equivalent, TBI, or concussion diagnostic or monitoring product.
VR feasible
Head-mounted RETINA prototypes have demonstrated feasibility and tolerability in active-duty military research settings, supporting the transition from lab systems toward scalable commercial deployment.
Future commercial and clinical deployments remain subject to product configuration, validation, and use context.
Standard cognitive screens often measure whether a person can complete a task. RETINA measures how efficiently the brain controls performance while the task becomes cognitively demanding.
Conventional cognitive tools can be influenced by age, education, motor speed, effort, mood, and compensation strategies. RETINA adds synchronized eye movements, pupil dynamics, manual responses, and task timing to capture performance patterns that may be missed when only overt task completion is measured.
This is the central scientific premise behind task-evoked neurocognitive measurement: subtle impairment may become more visible when the brain is required to sustain attention, inhibit distraction, manage competing cues, or respond consistently over time.
MRI-linked biology
One of RetinaTek's most important scientific differentiators is the published research connection between RETINA-related task-evoked performance metrics and MRI-based measures of white matter organization.
In military TBI research, RETINA-related metrics such as saccadic response-time variability and working-memory performance showed stronger and more distributed associations with DTI white matter findings than conventional cognitive scores or self-reported symptoms. These findings support biological plausibility for the RETINA platform and future clinical-development work.
The RETINA evidence base includes peer-reviewed publications across foundational measurement science, performance validity, cognitive load, military TBI, pupillometry, and MRI-linked biology.
