: The awareness of concussion as a serious and frequently occurring sports injury and its management has evolved significantly. One viable objective diagnostic tool is eye tracking technology. The authors hypothesized that while clinicians may be aware that assessing eye movements in concussed athletes can be beneficial, it is possible that, due to the novelty of the eye tracking technology and limited exposure, only a few actually use it in their practice. The study aimed to assess the awareness of eye movement deficits associated with concussion amongst sports medicine clinicians and to determine the utilization and perceptions of the eye tracking technology for concussion diagnosis.: An online 18-question survey was distributed internationally from January until December 2017 and completed by 171 sports medicine clinicians (sport physicians, therapists, general practitioners, neuropsychologists) from 32 countries.: Respondents indicated that subjectivity of assessments remained a major limitation of established diagnostic tools. Eye tracking technology, despite its potential to attenuate this limitation, was only used by 12% of respondents. To diagnose concussion, 77% did not use any eye movement assessment tools other than own clinical assessment. With the exception of abnormal pupil light reflex, which was checked by 68%, eye movement deficits were inspected by less than half of the respondents (46.3 ± 12%).: Even among sports medicine clinicians who regularly attend to patients with concussions, there is insufficient awareness that concussion can lead to abnormal eye tracking behavior. Lack of exposure to the sensitive eye tracking equipment may be a limiting factor for using eye movement metrics for concussion diagnostics. Facilitating the awareness of objective methods, like eye tracking technology, may help assure the appropriate continuum of identification and treatment for concussed athletes. Increasing educational opportunities and practical experience of clinicians regarding concussive symptoms and potential innovative technology is strongly advocated.
: 脑震荡作为一种严重且经常发生的运动损伤及其管理已经有了显著的发展。一种可行的客观诊断工具是眼动跟踪技术。作者假设，尽管临床医生可能意识到评估脑震荡运动员的眼球运动可能有益，但由于眼动跟踪技术的新颖性和有限的使用经验，实际上只有少数人在实践中使用它。本研究旨在评估运动医学临床医生对与脑震荡相关的眼球运动缺陷的认识，并确定眼动跟踪技术在脑震荡诊断中的应用和看法。: 2017 年 1 月至 12 月，作者在国际范围内进行了一项在线的 18 个问题的调查，共有来自 32 个国家的 171 名运动医学临床医生（运动医师、治疗师、全科医生、神经心理学家）完成了调查。: 受访者表示，评估的主观性仍然是既定诊断工具的主要限制。尽管眼动跟踪技术具有减轻这一限制的潜力，但只有 12%的受访者使用。为了诊断脑震荡，77%的人除了自己的临床评估外，不使用任何眼球运动评估工具。除了异常瞳孔光反射（68%的人会检查）外，不到一半的受访者（46.3±12%）会检查眼球运动缺陷。: 即使是经常接触脑震荡患者的运动医学临床医生，也没有充分意识到脑震荡会导致异常的眼动跟踪行为。缺乏对敏感眼动跟踪设备的接触可能是使用眼球运动指标进行脑震荡诊断的一个限制因素。提高对客观方法（如眼动跟踪技术）的认识，可能有助于确保对脑震荡运动员进行适当的识别和治疗。强烈提倡为临床医生提供更多关于脑震荡症状和潜在创新技术的教育机会和实践经验。
