The relation between the amplitudes of saccadic eye movements and the resting potential changes detected around human eyeballs under light and dark adaptations was clarified by means of simultaneous measurements of electrooculogram (EOG) and eye movements. The authors previously reported that the potential changes are proportional to the horizontal saccadic eye movements within +/- 15 degrees (visual angle) under conditions of the room light of approximately 60 lux. There are few reliable data indicative of the presence of the above relations under light and dark adaptations. The result of the simultaneous measurements of EOG and eye movements during the light and dark adaptation at 2-minute intervals in 9 normal subjects showed that the resting potential changes were in direct proportion of the amplitudes of the saccadic eye movements at any time within +/- 20 degrees. In these experiments, the eye positions were monitored with the eye mark recorder during the eye movements. In case the eye positions excursioned from a target, the exact EOG was calculated by measuring eye positions and correcting the EOG errors.
通过同步测量眼电图（EOG）和眼球运动，明确了在明适应和暗适应条件下，人眼球周围检测到的静息电位变化与扫视性眼球运动幅度之间的关系。作者之前报道过，在约60勒克斯的室内光条件下，电位变化与水平扫视性眼球运动在±15度（视角）范围内成正比。关于明适应和暗适应条件下上述关系存在的可靠数据很少。对9名正常受试者每隔2分钟在明适应和暗适应期间同步测量EOG和眼球运动的结果表明，在±20度范围内的任何时候，静息电位变化与扫视性眼球运动幅度成正比。在这些实验中，眼球运动期间用眼动标记记录器监测眼球位置。如果眼球位置偏离目标，通过测量眼球位置并校正EOG误差来计算准确的EOG。
