This trial is a single center, longitudinal, pilot study. One hundred mTBI patients with OMD, confirmed with objective testing by a OD, who fit inclusion/exclusion criteria will be initially identified by providers at the Hennepin County Medical Center (HCMC) TBI Clinic. No subject will be excluded on the basis of sex/gender, race or ethnicity. If interested, subjects will be consented then undergo an initial eye tracking. Within two weeks of the initial eye tracking, subjects will begin recommended NVR with occupational therapists (OT) at HCMC. Each NVR session will assess each subject's progress and following each NVR session, subjects will receive an eye tracking test. Additionally, within two months of the initial OMD diagnosis patients will follow up with the OD every two months until their OMD is resolved or until one year following their diagnosis. Subjects will also undergo an eye tracking test after each OD follow up appointment. Eye tracking visual stimulus measurements will be compared to OD diagnostic measurements and assessments.
