“…These patients showed higher phase lag times (slower response to stimulus, most dramatic at higher speeds) and reduced velocities (DiCesare et al, 2017). This was also supported by Evans and colleagues who found increased mean error during faster smooth pursuit conditions (n=26, average 32 days post injury +/-37) compared to healthy counterparts (Evans, 2016).…”

“…Multiple groups have studied smooth pursuit eye movements in mTBI patients in both clinical and laboratory settings (Astafiev et al, 2015;Cifu et al, 2015;Danna-Dos-Santos et al, 2018;DiCesare et al, 2017;Diwakar et al, 2015;Evans, 2016;Heitger et al, 2009;Kelly, 2017;Maruta et al, 2014;Maruta et al, 2010;Richard et al, 2009;Stubbs et al, 2019). These patients generally experience a slower tracking velocity compared to healthy controls with a higher mean positional error which has also been found in persistently symptomatic ('postconcussion syndrome', PCS) patients (Astafiev et al, 2015;Cifu et al, 2015;Danna-Dos-Santos et al, 2018;Diwakar et al, 2015;Heitger et al, 2009;Maruta et al, 2010).…”

Eye movements in mild traumatic brain injury: Ocular biomarkers

Mild traumatic brain injury (mTBI, or concussion), results from direct and indirect trauma to the head (i.e. a closed injury of transmitted forces), with or without loss of consciousness. The current method of diagnosis is largely based on symptom assessment and clinical history. There is an urgent need to identify an objective biomarker which can not only detect injury, but inform prognosis and recovery. Ocular motor impairment is argued to be ubiquitous across mTBI subtypes and may serve as a valuable clinical biomarker with the recent advent of more affordable and portable eye tracking technology. Many groups have positively correlated the degree of ocular motor impairment to symptom severity with a minority attempting to validate these findings with diffusion tract imaging and functional MRI. However, numerous methodological issues limit the interpretation of results, preventing any singular ocular biomarker from prevailing. This review will comprehensively describe the anatomical susceptibility, clinical measurement, and current eye tracking literature surrounding saccades, smooth pursuit, vestibulo-ocular reflex, vergence, pupillary light reflex, and accommodation in mTBI.

“…The experimental designs of the reviewed articles included six types of eye tracking tests: smooth pursuit (ten studies), self-paced saccades (five studies), reflexive saccades (eight studies), memory-guided saccades (two studies), antisaccades (four studies), and fixations (four studies) (tables 4 and 5)). Some researchers opted to analyse only one type of eye movements: smooth pursuit (Maruta et al 2014, Diwakar et al 2015, Evans et al 2016, Kelly 2017, Katrahmani and Romoser 2018, self-paced saccades (Brewin 2017, Taghdiri et al 2018, reflexive saccades (Drew et al 2007, Pearson et al 2007, or memory-guided saccades (Heitger et al 2002). Other researchers used a combination of two or more eye tracking tests (Richard et al 2009, Dicesare et al 2015, Johnson et al 2015a, Mullen et al 2016, Ledwidge et al 2017, Webb 2017, Danna-Dos-Santos et al 2018.…”

Eye tracking technology in sports-related concussion: a systematic review and meta-analysis

et al. 2018

View full text Add to dashboard Cite

Objective: The development of objective quantitative tools for the assessment and monitoring of sports-related concussion is critical. Eye tracking is a novel tool that may provide suitable metrics. The aim of this review was to appraise current evidence for the use of eye tracking technology in sports-related concussion assessment and monitoring. Approach: A systematic literature review was conducted following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. A search was run using Google Scholar, Microsoft Academic and PubMed for literature published between January 1980 and May 2018. Included were empirical research studies in English where at least 50% of the research participants were athletes, the participants were individuals with a diagnosis of concussion, and eye movements were measured using an eye tracking device. Main results: This systematic review integrates 21 publications on sports-related concussion and eye tracking technology, nine of which also qualified for the meta-analysis. Overall, the literature reported significant findings for variables in each of the four classes of eye tracking measurements (movement, position, count, and latency). Meta-comparison was made for seven variables for the acute concussions (the difference between the concussed and the control groups was significant for all of them) and one variable for the latent concussions (the difference was not significant). Significance: Most saccadic and pursuit deficits may be missed during clinical examination, and therefore eye tracking technology may be a useful and sensitive screening and monitoring tool for sports-related concussions. The inconsistencies between the eye movement metrics and methodology still make inferences challenging; however, using tasks that are closely related to brain areas involved in executive functions (such as memory-based saccade or antisaccade tasks) in the acute injury phase holds promise in differentiating between athletes who have a concussion compared to those who do not.
