We developed a technique for DC-coupled ERG recording of the alert human. The equipment consists of three units: a new cornea suction glass, a separate electrode, and a vacuum control device. We get stable recordings of more than one-half hour. By comparison with the EOG the identity of the EOG "on"-peak and ERG c-wave is assured. A fine structure of DC-ERG recording of 100 muV amplitude is closely correlated to the variation of the blood pressure in the ophthalmic artery. It may either be caused by the variable electric conductivity of the eyeball due to the blood pressure or it may reflect a variation of the retinal potential itself.
我们开发了一种用于清醒人类直流耦合视网膜电图（ERG）记录的技术。该设备由三个单元组成：一个新型角膜吸附镜、一个独立电极和一个真空控制装置。我们获得了超过半小时的稳定记录。通过与眼电图（EOG）比较，确定了EOG“开”峰与ERG c波的一致性。幅度为100微伏的直流ERG记录的精细结构与眼动脉血压变化密切相关。这可能是由于血压导致眼球电导率变化引起的，也可能反映了视网膜电位本身的变化。
