War and combat exposure pose great risks to the vision system. More recently, vision related deficiencies and impairments have become common with the increased use of powerful explosive devices and the subsequent rise in incidence of traumatic brain injury (TBI). Studies have looked at the effects of injury severity, aetiology of injury and the stage at which visual problems become apparent. There was little discrepancy found between the frequencies or types of visual dysfunctions across blast and non-blast related groups, however complete sight loss appeared to occur only in those who had a blast-related injury. Generally, the more severe the injury, the greater the likelihood of specific visual disturbances occurring, and a study found total sight loss to only occur in cases with greater severity. Diagnosis of mild TBI (mTBI) is challenging. Being able to identify a potential TBI via visual symptoms may offer a new avenue for diagnosis.
战争和战斗暴露对视觉系统造成巨大风险。最近，随着强力爆炸装置的使用增加以及外伤性脑损伤 (TBI) 的发病率上升，与视觉相关的缺陷和损伤变得越来越常见。研究着眼于损伤严重程度、损伤病因以及视觉问题显现的阶段的影响。在与爆炸或非爆炸相关的两组之间，视觉功能障碍的频率或类型几乎没有差异，然而，只有那些与爆炸相关的损伤才会出现完全失明的情况。一般来说，损伤越严重，出现特定视觉障碍的可能性就越大，一项研究发现，只有在更严重的情况下才会出现完全失明。轻度 TBI (mTBI) 的诊断具有挑战性。通过视觉症状识别潜在的 TBI 可能为诊断提供新途径。
