Combat blast is an important cause of traumatic brain injury (TBI) in the
Department of Veterans Affairs polytrauma population, whereas common causes of TBI in the civilian sector include motor vehicle accidents and falls. Known
visual consequences of civilian TBI include compromised visual acuity, visual
fields, and oculomotor function. The visual consequences of TBI related to blast
remain largely unknown. Blast injury may include open globe (eye) injury, which
is usually detected and managed early in the rehabilitation journey. The
incidence, locations, and types of ocular damage in eyes without open globe
injury after exposure to powerful blast have not been systematically studied.
Initial reports and preliminary data suggest that binocular function, visual
fields, and other aspects of visual function may be impaired after blast-related
TBI, despite relatively normal visual acuity. Damage to the ocular tissues may
occur from blunt trauma without rupture or penetration (closed globe injury).
Possible areas for research are development of common taxonomy and assessment
tools across services, surgical management, and outcomes for blast-related eye
injury; the incidence, locations, and natural history of closed globe injury;
binocular and visual function impairment; quality of life in affected service members; pharmacological and visual therapies; and practice patterns for screening, management, and rehabilitation.
