What’s new for ‘concussion eye tracking’ in PubMed

Sep 28, 2018

A study conducted jointly by NKI and Allegheny General Hospital found that high-school athletes who had sustained a concussion had significant, measurable differences than controls in oculomotor function, particularly for smooth pursuit, optokinetic nystagmus (OKN), as well as a combined ‘reaction time and saccade’ test.  In addition, OKN gain was reduced and more variable in subjects assessed more than three weeks after injury.  The results of this study indicate that oculomotor and reaction time tests can be used as a reliable, adjunctive tool in the assessment of concussion, and that OKN results appear to be associated with a prolonged expression of concussion symptoms.
