Oculomotor Response as an Objective Assessment for Mild TBI in the Pediatric Population (2017-2018)


In children, brain injury is complex and common, and currently it is a leading source of injury and death. Sports-related concussions in children and adolescents (5-18 years) account for 30-60% of all pediatric concussions.

Though mild traumatic brain injury (mTBI) is an important public health issue for both the general pediatric population and youth athletes, challenges exist in obtaining objective diagnoses of mTBI or quantifying the physiological implications of cumulative subconcussive (low-level) insults.

Establishing a link between the clinical diagnoses and objective diagnostic tools that are sensitive over a spectrum of pathophysiology that includes the minimally sub-concussed child to those that experience many sub-concussive events or are clinically diagnosed with a concussion are crucial in developing mitigation strategies.

Project Description

To bridge this gap, this Bass Connections project will assess youth athletes with an oculomotor assessment routine that includes reflexive (pro-saccades), anti-saccades and memory guided saccades (MGS) and compare these data to in-season documentation of concussion and level of impact/practice exposure.

The sample population includes youth athletes from five years of age to the high school level. Over a multi-year period, multiple age levels and levels of play will be assessed. Changes in oculomotor response when compared to documented injury will be assessed as an objective tool for diagnosing concussion and quantifying the pathophysiology of cumulative sub-concussive insults to the pediatric brain. This project team will generate data from local high school and Pop Warner athletes in-season.

Anticipated Outcomes

Findings presented to the public and in a scientific context (posters, publications); eventual manuscripts and in the interim numerous abstracts for national and regional conferences prepared; at least one opportunity for presentations or posters at a regional conference (UNC-Chapel Hill)


Summer 2017 – Spring 2018

  • Summer 2017: Preferred Summer Internship to span Duke’s 2nd Summer Session, July 3 through August 13; opportunity exists to lengthen the internship in the weeks prior to July 3 as well as after August 13
  • Fall 2017: Mid-point Year 3 oculomotor assessment; end-of-season Year 3 oculomotor assessment; analysis of oculomotor assessments, baseline through end-of-season Year 3
  • Spring 2018: Out-of-season oculomotor assessment
