electrooculogram EOG battery model of eyeball cross-talk standing potential

项目摘要

Electrooculogram (EOG) is applied to clinical diagnosis in the ophthalmology field, but it is very difficult to measure the absolute values of the standing potentials around the eye because of changes in various factors such as the pasting positions of electrodes, the kinds of electrodes and the subjects. Therefore, the changes in the standing potentials caused by eye movements are measured in clinical tests instead of measuring the absolute values of the standing potentials.We have already reported that the changes in the standing potentials could be analyzed by applying a battery model to the eyeball. In this study, the various characteristics of EOG was measured and simulated applying the battery model to the eyeball. The battery model of the eyeball were found to be in good agreement with the experimental results for the difference in the pasting positions of electrodes.In this report, the EOG characteristics in case of the deviation of the eye line from frontal to right or left was analyzed applying the battery model. And the cross-talk, the contralateral potential was simulated using this model.It was simulated from the battery model that the potentials on the corneal apex had the maximum values. We tried to measure the absolute values of standing potentials to confirm the above analysis. The maximum value of the potential was experimentally measured from the electrode pasted on the closed eyelid.Measuring the absolute values of the standing potentials and applying the battery model to the eyeball enable us to analyze the detailed characteristics of EOG.

电击图（EOG）应用于眼科领域的临床诊断，但是由于各种因素的变化，例如电极的粘贴位置，电极类型和受试者，因此很难测量眼睛周围的站立电位的绝对值。因此，在临床测试中测量了由眼睛运动引起的站立电位的变化，而不是测量站立电位的绝对值。我们已经报告说，可以通过将电池模型应用于眼球来分析站立电位的变化。在这项研究中，测量并模拟了EOG的各种特征，并将电池模型应用于眼球。发现眼球的电池模型与电极粘贴位置的差异的实验结果非常吻合。在本报告中，在眼线从额叶到右或左偏离偏离的EOG特性以应用电池模型分析。和串扰，使用此模型模拟对侧电势。它是通过电池模型模拟的，即角膜顶点上的电势具有最大值。我们试图衡量站立电位的绝对值以确认上述分析。通过粘贴在闭合眼睑上的电极实验测量电势的最大值。衡量站立电势的绝对值并将电池模型应用于眼球，使我们能够分析EOG的详细特性。
