A concussion occurs when a direct or indirect force is transmitted to the brain, causing a change in brain function. Given that approximately half the brain circuits are involved in vision and the control of eye movements, a concussion frequently results in visual symptoms. Ophthalmic abnormalities are helpful in the assessment of acute concussion, identified by rapid automized naming tasks and eye movement assessments. In particular, convergence, eye-tracking and the vestibular-ocular motor screening tool may be used. For patients suffering from post-concussion syndrome more than 3 months from the original injury, abnormalities may be found in convergence, accommodation and smooth pursuit. Orthoptic exercises are useful rehabilitation tools to allow patients to return to school, work and recreation. This article provides a brief overview of concussion as it relates to vision and ophthalmic practice.

脑震荡的视觉效果：回顾

当直接或间接的力量传递到大脑时，就会发生脑震荡，导致大脑功能发生变化。鉴于大约一半的大脑回路涉及视觉和眼球运动的控制，脑震荡经常导致视觉症状。眼部异常有助于评估急性脑震荡，通过快速自动命名任务和眼球运动评估来识别。特别是，可以使用会聚、眼球追踪和前庭眼运动筛查工具。对于脑震荡后综合征患者，距原伤3个月以上，在收敛性、调节性和平稳性追求上可能会出现异常。矫形锻炼是有用的康复工具，可以让患者重返学校、工作和娱乐。
