The relationship between eye movements and mTBI has mainly been studied from a clinical perspective. In the literature review below, we shortlisted publications showcasing the relevance of studying eye movements to quickly assess and follow up on traumatized patients in a quantified way. The first article shows promises of eye-tracking for detection in the sports field, the second article for the follow-up during the consultation, and the third article shows the value of eye movements together with the gold standards for follow-up.
Researchers found that fixational saccade amplitudes were significantly different in the concussion group, but only when fixating on the center of the raster. This task specificity suggests that task optimization may improve differentiation and warrants further study.
The concussion group is shown in red and control in blue; error bars are ±SD. Figure (a) shows the results for the center fixation tasks while figure (b) shows the results for the peripheral fixation tasks.
Results from researchers suggest that visual tracking performance metrics reflect clinical symptoms when assessed within 2 weeks of concussion.
Recent studies show that three of the 7 oculomotor tasks (antisaccade, self-paced saccade, and memory-guided saccade) administered showed significant differences between the recently concussed group compared with normal volunteers.
