A Houston-based neuro-optometric practice serving plaintiff and defense personal injury firms across the entire state of Texas.
The forensic vision specialty is based in Houston, where Dr. Rizwan Jaffer, O.D., practices under Texas Optometry License #7014TG. From that Houston base, the practice supports plaintiff and defense personal injury counsel across the entire state — one licensed neuro-optometrist, one methodology, one set of published clinical reference ranges, and one signed report format regardless of the venue.
Every stage of an engagement — records review, written case analysis, causation opinion within scope, in-person evaluation of the client, deposition, and trial testimony — is priced and scoped in writing before work begins. Firms outside the Houston metro do not travel to Houston for anything other than the specific stage that requires an in-person examination, and even then, that stage is typically the client's visit rather than counsel's.
The practice supports personal injury counsel throughout Texas without maintaining satellite locations — a single Houston base keeps the methodology, instrumentation, and reporting consistent from case to case, no matter where the venue sits. Dallas–Fort Worth files center on high-volume collision, rideshare, and premises matters flowing through Dallas and Tarrant County dockets, alongside commercial-vehicle cases from the I-20, I-30, and I-35W corridors. San Antonio and the surrounding I-10 / I-35 corridor draw a heavy share of highway rear-end and lane-change collisions filtering through Bexar County. Austin and Central Texas — Travis and Williamson Counties along I-35, MoPac, and SH-130 — bring a rising share of post-collision presentations that are functional and near-visual rather than structural. El Paso and the West Texas border corridor add long-haul I-10 freight, cross-border commercial traffic, and industrial matters that span the state line. Corpus Christi and the Coastal Bend contribute refinery, port, and highway files where head-impact mechanisms are common. The Rio Grande Valley — McAllen, Edinburg, Brownsville, and Harlingen — sits on one of the busiest commercial-vehicle corridors in Texas, feeding cross-border freight into Hidalgo and Cameron Counties. Lubbock and the South Plains handle highway matters on I-27 and US-84 alongside agricultural-equipment and oilfield-related injuries. Beaumont–Port Arthur and the Southeast Texas industrial corridor generate a case profile dominated by refinery, petrochemical, and heavy-industry incidents alongside dense I-10 commercial traffic. All of these venues are served from Houston under the same statewide engagement pattern.
The case-type pages describe how a neuro-optometric workup applies to the mechanism at issue. Each is written for attorneys evaluating whether an objective oculomotor evaluation fits the specific matter.
Attorney search terms and physician terminology often use different words for the same clinical entity. The definitions below describe how these terms are used throughout the practice's written reports and testimony.
Neuro-optometric evaluation. A clinical examination focused on the brain-driven components of the visual system — how the eyes move, aim, track, and coordinate — rather than only on structural eye health or single-eye acuity. Performed by a neuro-optometrist, a Doctor of Optometry with a clinical focus on post-trauma visual dysfunction.
Post-trauma vision syndrome (PTVS). The cluster of oculomotor and visual-processing findings that regularly appears after head impact, concussion, whiplash, or blast exposure — including convergence insufficiency, accommodative dysfunction, saccadic dysfunction, photophobia, and visual midline shift. See the dedicated resource page at post-trauma vision syndrome.
Oculomotor dysfunction. A measurable deficit in one or more of the ocular-motor subsystems — smooth pursuit, saccades, fixation stability, convergence, or vergence facility — quantified against published clinical reference ranges.
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.
Dr. Rizwan Jaffer, O.D., is a Therapeutic Optometrist and Optometric Glaucoma Specialist practicing under Texas Optometry License #7014TG. The forensic vision specialty focuses on neuro-optometric evaluation of post-trauma vision syndrome and optometry expert witness services for civil personal injury matters throughout Texas.
Yes. The Houston-based forensic vision practice supports plaintiff and defense counsel across all of Texas. Engagements are coordinated remotely; the in-person clinical evaluation is scheduled at one of six Houston-area locations when required. Travel and logistics are quoted in writing before scheduling.
Yes. Engagements are considered on the merits, and every retention proceeds from the same methodology, the same digital measurements, and the same published clinical reference ranges regardless of which side has retained the practice. Written scope, fee schedule, and CV are provided before any work begins.
The recorded digital measurements for each of the five oculomotor subsystems (smooth pursuit, saccades, fixation stability, convergence, and vergence facility), the named clinical reference range for every value, a test validity analysis, a clinical impression stated to a reasonable degree of optometric certainty, and — where included in the scope of the engagement — a written causation discussion.
Scheduling is coordinated directly with counsel and quoted in writing before any appearance is confirmed. Video and in-person options are offered as the engagement requires.
