Purpose Over 85% of traumatic brain injuries (TBI) are considered “mild”, also referred to as “concussion”. Mild TBI is increasingly recognized as an important public health problem. Despite their designation as “mild”, adverse outcomes from such injuries are significant, with 25% of patients still impaired at one year. Visual difficulties are common, reported by two‐thirds of patients in a Veterans Administration study. Methods Visual symptoms of mild TBI typically include blurring, light sensitivity, eyestrain, difficulty with near focus, trouble tracking, seeing haloes around lights, and diplopia (monocular and binocular). Results Despite the high incidence of visual symptoms, results of standard eye examination and neuro‐ophthalmic testing are typically normal. Conventional neuro‐imaging also fails to demonstrate objective evidence of neurologic dysfunction in most cases. Recent developments in neuroimaging (particularly diffusion tensor imaging) and serologic testing (S‐100B) have provided some correlates of such injury. Conclusion New information from neuroimaging and serologic testing has helped to provide some objective markers for post‐concussive syndromes. The diagnosis of such post‐traumatic syndromes remains largely clinical.
