脑震荡可能会导致大脑功能的微妙变化，涉及视觉系统的测试可以探测更高的皮层功能，并增加我们检测这些变化的灵敏度。脑震荡是急性的，有时更持久地与平衡，认知和视力异常有关。视觉系统涉及大约一半的大脑回路，包括许多容易受到头部撞击的区域。脑震荡后，神经眼科检查通常会发现会聚、调节、前庭眼反射、眼肌平衡、扫视和追踪的异常。King-Devick（K-D）测试是一种视觉性能测量，当与作为运动性脑震荡评估工具（第三版; SCAT3）。便携式眼动追踪器和瞳孔测量法可能在未来改善我们脑震荡后的神经眼科评估。将视觉任务与神经成像和神经生理学相结合，可以检测到细微的变化，可以改善我们做出适当的返回游戏决定的能力，并可能决定对脑震荡长期后遗症的易感性。
Concussion may lead to subtle changes in brain function, and tests involving the visual system probe higher cortical functioning and increase our sensitivity in detecting these changes. Concussions are acutely and sometimes more persistently associated with abnormalities in balance, cognition, and vision. The visual system involves roughly half of the brain's circuits, including many regions susceptible to head impacts. After a concussion, the neuro-ophthalmologic exam commonly detects abnormalities in convergence, accommodation, the vestibulo-ocular reflex, ocular muscle balance, saccades, and pursuit. The King-Devick (K-D) test is a visual performance measure that may increase the sensitivity of detecting concussions on the sideline when used in combination with tests of cognition and balance that are part of the Sports Concussion Assessment Tool (3rd ed.; SCAT3). Portable eye movement trackers and pupillometry may in the future improve our neuro-ophthalmic assessment after concussions. Combining visual tasks with neuroimaging and neurophysiology has allowed subtle changes to be detected, may refine our ability to make appropriate return-to-play decisions, and could potentially determine susceptibility to long-term sequelae of concussion.
