Objective, digitally measured oculomotor documentation for mild TBI cases where imaging is read as normal — from records review through trial testimony statewide.
Mild traumatic brain injury cases share a familiar evidentiary pattern: the client describes real, persistent symptoms — reading difficulty, screen intolerance, headaches, dizziness, intermittent double vision — while CT and MRI reports return unremarkable and neurological examinations focus on gross deficits that are not present. The functional impairment is real; the imaging record does not show it.
A standardized oculomotor battery is designed to occupy exactly this evidentiary gap. Smooth pursuit, saccadic accuracy, fixation stability, convergence, and vergence facility are brain-driven functions that can be disrupted by mild TBI in the absence of a structural lesion, and they are measurable with digital instrumentation and compared, one value at a time, against published clinical norms.
The forensic vision practice does not replace the treating neurologist, physiatrist, or vision-therapy provider. It produces a discrete, timestamped, machine-measured dataset that sits alongside the treating-provider record and can be independently reviewed and, where clinically indicated, repeated for serial comparison. The methodology is reproducible across dates and across examiners.
Each signed report presents the recorded measurements, the named clinical reference range for every value, a test validity analysis, and a clinical impression stated to a reasonable degree of optometric certainty. The report is written to be legible to counsel, opposing counsel, and the court, not only to another optometrist.
The clinical workup pairs digital oculomotor measurement with direct clinical observation scored by a licensed Texas optometrist. Digital values are compared, one by one, against published normative ranges drawn from the peer-reviewed optometric literature — never an internal benchmark.
Each written report presents the recorded measurements, the named clinical reference range for every value, a test validity analysis, and a clinical impression stated to a reasonable degree of optometric certainty. The methodology is reproducible across dates and examiners so a second dataset can be run at 12 weeks for serial documentation.
Tracking accuracy of a moving target; deficits present as saccadic intrusions.
Speed and accuracy of rapid gaze shifts between fixed targets.
Steadiness of gaze on a stationary target over sustained periods.
Near point of convergence in centimeters against clinical norms.
Rate at which the eyes re-align between near and distance targets.

Yes. CT and MRI evaluate the structure of the brain; the oculomotor battery evaluates function. Mild TBI can disrupt oculomotor function in the absence of a structural finding, and the workup is specifically designed to produce a measurable record of that functional state.
The assessment is diagnostic and forensic — it documents the current state and, on re-assessment, the trajectory. It does not replace vision therapy notes; it produces an independent, standardized dataset that can be reviewed alongside them and used as a comparison point over time.
Clinical impressions are stated to a reasonable degree of optometric certainty and reference the measurements, the published norms, and the documented history. Broader causation opinions are addressed within the scope agreed to in writing before the engagement.
