Abnormal Dynamic Visual Function and Associated Symptomatology in Mild Traumatic Brain Injury
Abstract
Traumatic brain injury (TBI) is a leading cause of death and disability in the United States, and the incidence of mild TBI among military members has increased since 2000. Oculomotor deficits have been identified as a phenotypical subtype post mTBI and it has been shown to be associated with clinical symptoms after injury. Vision-related symptoms include reading difficulties, blurred or double vision, difficulty switching focus from near to far, photophobia, discomfort in busy and dynamic environments, and visual attention deficits. It has also been shown that individuals have increased symptoms if they also have an additional phenotype, such as vestibular dysfunction. The addition of the vestibulo-ocular phenotype may account for increased visually related symptoms, including movement-related dizziness and blurred vision, as individuals would not only be symptomatic to moving objects, but they would also have additional symptoms as they move their head while trying to fixate on stationary objects. This study directly addresses the focus area Visual dysfunction as related to a military-relevant traumatic event and will address the critical gaps in understanding the myriad of visual symptoms, corresponding vision related deficits, and their associations with motion sensitivity and visual attention following mTBI.
