What this Trial Is About
Post-concussive vision symptoms affect many Veterans who have experienced traumatic brain injury (TBI). One common issue is trouble with near vision, a problem that may persist long after the acute injury. Double vision or difficulty focusing on close objects can affect reading and depth perception. Poor reading can interfere with academic or work performance, and loss of near focusing can affect jobs that require fine motor tasks like machining and electrical work. Even having trouble using a smartphone can have a substantial impact on both work and social function. Near vision impairment after TBI is not well understood, and treatments are limited. The goal of this project is to investigate novel virtual-reality assessments and training games to improve the near vision diagnosis and home-based rehabilitation. Restoring normal near vision function could have a large impact on the fulfillment of Veterans' educational, career, and overall life goals.
