运动视差是从观察者平移产生的视网膜运动中恢复深度的能力，对于视觉深度感知非常重要。最近的研究表明，运动视差的深度感知依赖于慢眼动系统。众所周知，乙醇中毒会降低该系统的增益，从而产生执法部门现场清醒测试旨在揭示的水平凝视眼球震颤。目前的研究表明，由于乙醇中毒对慢眼动系统的影响，会损害运动视差的深度感知。急性乙醇中毒使运动视差任务的阈值显着增加，而依赖双眼视差的相同测试的阈值不受影响。也许运动视差的失败在酒精相关的驾驶事故中发挥了作用；由于酒精对眼球运动的影响，醉酒的驾驶员可能无法从运动视差中获得不准确或不充分的信息来判断障碍物的相对深度。
Motion parallax, the ability to recover depth from retinal motion generated by observer translation, is important for visual depth perception. Recent work indicates that the perception of depth from motion parallax relies on the slow eye movement system. It is well known that ethanol intoxication reduces the gain of this system, and this produces the horizontal gaze nystagmus that law enforcement's field sobriety test is intended to reveal. The current study demonstrates that because of its influence on the slow eye movement system, ethanol intoxication impairs the perception of depth from motion parallax. Thresholds in a motion parallax task were significantly increased by acute ethanol intoxication, whereas thresholds for an identical test relying on binocular disparity were unaffected. Perhaps a failure of motion parallax plays a role in alcohol-related driving accidents; because of the effects of alcohol on eye movements, intoxicated drivers may have inaccurate or inadequate information for judging the relative depth of obstacles from motion parallax.
