Saccades appear to be a reliable measure of brain dysfunction following Traumatic Brain Injury (TBI). Four subjects were chosen at random having a history of traumatic brain injury and active symptomatology. Trauma and chronic stresses are potentially associated with certain distortion patterns of the pelvis and cranium in the Sacro Occipital Technic® Methods (SOT™) of chiropractic and Chiropractic Craniopathy.

Brain Science
Chronic low-level blast exposure has been linked with neurological alterations and traumatic brain injury (TBI) biomarkers. Impaired smooth-pursuit eye movements (SPEM) are often associated with TBI. The purpose of this study was to determine whether long-term operators of low-level blast exposure or high-caliber weapons use displayed oculomotor behaviors that differed from controls.

The perinatal temporal window is a highly vulnerable time in which environmental factors, such as nutrients, drugs, infections, chemicals, and stress, experienced by the mother can be communicated to the offspring and produce lasting consequences on the newborn brain. Eye tracking is a non-invasive method used to understand these changes.

Mild Traumatic Brain Injuries (mTBI) can lead to visual processing deficits, including decreased visual acuity, visual field impairment, eye movement dysfunction- including vergence, saccadic, smooth pursuit movements, and an increase in mental workload during visual tasks. The purpose of this project was to examine the relationship between brain activity and visual-motor deficit in participants with a recent mTBI compared to healthy controls.

Brain Injury
Deficits in smooth-pursuit eye movements (SPEM) are often associated with mild traumatic brain injury (TBI). Eye tracking tests serve as a quick objective clinical tool to assess such predictive visual tracking. In this study, SPEM was assessed along circular, horizontal and vertical trajectories in adolescents with concussion and age-matched controls.

Head and neck position induced by statically maintained head turns is associated with lower stability scores than the standardized head neutral position of the mCTSIB in Post-Concussion Syndrome (PCS) subjects but not in healthy controls. Head positions of the neutral plane provide biomarkers that differentiate subjects suffering from PCS from healthy normal subjects.

Convergence insufficiency is a common binocular vision disorder affecting approximately 5% of the population in the United States. It is often associated with a host of symptoms that occur when doing near work, such as reading and computer viewing. This article reviews the existing literature on convergence insufficiency including etiology, diagnosis, sensorimotor findings, and management.

Recent studies have found that symptoms associated with convergence insufficiency are reduced by in-office vision therapy with supplemental home therapy. This retrospective study was designed to evaluate the changes in symptoms using an automated, home computer vision therapy program (HTSTM) in accommodative/vergence disorders.

Journal of Behavioral Optometry
Vision therapy or orthoptics is the standard treatment for symptomatic accommodative-vergence anomalies and amblyopia. Computerization of vision therapy has improved treatment results by: standardizing protocols; providing positive or negative reinforcement based upon responses; eliminating experimental (therapist) bias in research and/or therapy; and standardizing stimuli and methodology for diagnosis/treatment.
