前庭眼球反射(VORS)减弱或缺失的人被认为在足够快的头部运动时眼睛稳定有困难。这提出了一种假设，即迷宫般的缺陷个体在移动的机动车中可能会损害视觉能力。10名可能有异常VOR的持证司机被招募来评估这种可能性。通过测量眼球对静态倾斜头部的反转反应和冷热刺激引起的眼球震颤来评价他们的迷路功能。每个人都接受了一项视觉任务的评估，即在坐着不动和坐在汽车里时，回答关于从静止标志上读取的字母数字信息的问题。运动状态下的视力得分往往比静止状态下的低。此外，这些减少似乎与眼球对滚的大小比与热量反射的关系更密切。这些结果对耳石器有一定的意义。半规管功能，前庭受损个体的车辆手术，以及使用前庭毒性药物的临床治疗评估。
Persons with diminished or absent vestibulo‐ocular reflexes (VORs) are thought to have difficulty with ocular stabilization during sufficiently rapid head movements. This suggests the hypothesis that labyrinthine defective individuals might have impaired visual abilities when in a moving motor vehicle. Ten licensed drivers likely to have abnormal VORs were recruited to assess this possibility. Their labyrinthine function was indexed by measurements of ocular counterroll responses to static head tilt and the nystagmus induced with caloric stimulations. Each person was evaluated on a visual task, i.e., answers to questions about alphanumeric information read from a stationary sign while sitting still and while riding in a car. Comparisons of vision scores tend to be lower in the moving than in the still condition. Furthermore, these decrements appear more closely related to the magnitudes of ocular counterroll than to the caloric reflexes. These results have implications concerning otolithic us. semicircular canal function, vehicle operations by vestibularimpaired individuals, and evaluations of clinical treatments which employ vestibulotoxic drugs.
