这项研究建立了规范性数据和测试程序的眼科评估工具。眼功能评估工具为前庭/眼动筛查评估确定视觉目标，并提供额外的指标，有助于区分可能由脑震荡引起的正常和异常眼功能。使用眼疲劳评估工具评估既往无脑震荡病史的健康受试者的眼疲劳耐受性。招募健康参与者（N=376，平均年龄20.4岁，范围11至34岁，先前没有自我报告的脑震荡史）执行以下三项任务，每次60秒：1）水平扫视，2）垂直扫视，3）聚散跳跃。参与者被要求在每项任务中尽可能快地在两个目标之间交替视觉注视，而不会超过或低于视觉目标。分析了一分钟测试的最初30秒和后30秒之间的眼球运动次数的差异。在所有三项任务中，在最初和后30秒之间的眼球运动次数（水平扫视[最初30秒为70±15;后30秒为63±13]，垂直扫视[68±14; 63±13]和聚散跳跃[43±11; 39±10]）观察到统计学差异（P <0.001）。基于性别，在最初和后30秒之间的眼球运动次数或眼球运动变化方面没有发现显著差异。这些结果建立了各种眼动的规范数据库。这些数据可能用于比较可能由于创伤性脑损伤而具有双眼耐力障碍的不同患者人群，例如脑震荡患者。
This study establishes normative data and a testing procedure for the oculomotor assessment tool. The oculomotor assessment tool standardizes visual targets for the Vestibular/OculoMotor Screening assessment and provides additional metrics that may aid in the differentiation between those with normal and abnormal oculomotor function potentially caused by a concussion. To assess the oculomotor endurance of healthy participants with no prior self-reported history of concussions utilizing the oculomotor assessment tool. Healthy participants (N=376, average age of 20.4 years, range of 11 to 34 years, with no prior self-reported history of concussions) were recruited to perform the following three tasks for 60 seconds each: 1) horizontal saccades, 2) vertical saccades, and 3) vergence jumps. The participants were instructed to alternate visual fixation between two targets for each of the tasks as fast as they could without over or undershooting the visual target. The differences in the number of eye movements between the initial and latter 30-seconds of the one-minute test were analyzed. A statistical difference (P < .001) was observed in the number of eye movements for all three tasks (horizontal saccades [70±15 for initial 30-seconds; 63±13 for latter 30-seconds], vertical saccades [68±14; 63±13], and vergence jumps [43±11; 39±10]) between the initial and latter 30-seconds. No significant differences were identified in the number of eye movements or the change in eye movements between the initial and latter 30-seconds based upon sex. These results establish a normative database for various eye movements. These data could potentially be used to compare different patient populations who have binocular endurance dysfunctions potentially due to traumatic brain injury, such as patients with concussion(s).
