Objective: To evaluate the relationship between fractional anisotropy and vestibular/Ocular-Motor Screening (VOMS) in concussion.
Methods: Diffusion tensor MRI included fractional anisotropy of the Brain and vestibular/ocular-motor screening were conducted on 10 patients with concussion who were diagnosed in Toho University Ohashi medical center sports-related concussion clinic from April, 2017 to March, 2018. Fractional anisotropy was extracted from 2 regions of interest in corpus callosum and corticospinal tract. Detailed vestibular/ocular-motor screening with an emphasis on anti saccadic and convergence eye movement was also conducted. The FA values in the corpus callosum and the corticospinal tract were compared between the 2 groups of 6 patients (Group V) who failed either in VOMS and 4 cases (Group NV) who did not admit it .
Results: Mean FA values in the corpus callosum and corticospinal tract in the Group V were 0.70 and 0.56. Mean FA values in the corpus callosum and corticospinal tract in the Group NV were 0.43 and 0.49.
Conclusions: Our result suggests that the FA value of the corpus callosum were shown to explain the fluctuation of anti saccadic and convergence eye movement.
