The goals of this research study are to improve objective, timely identification of mTBI related visual dysfunctions and assessment of the effectiveness of NVR. A positive outcome will greatly impact diagnosis and care of mTBI patients with vision dysfunction, as objective assessments will be more widely and readily available and NVR will be more utilized by the medical community. Overall post-mTBI functional outcomes will improve, significantly lessening this major public health concern affecting patients, families, communities, and society.
