Analysis of a Battery Model of the Eyeball based on DC Characteristics of Electrooculogram (EOG)

眼电(EOG)用于眼科临床诊断，但由于电极粘贴位置、电极种类、受试者等多种因素的影响，测量眼周站立电位的绝对值非常困难。因此，在临床试验中测量眼球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。我们已经报道过，可以通过在眼球上应用电池模型来分析站立电位的变化。在本研究中，将电池模型应用于眼球，对眼电的各种特性进行了测量和模拟。由于电极粘贴位置的不同，眼球的电池模型与实验结果吻合较好，本文利用电池模型分析了眼线从正面向右或向左偏移时的眼电特性。并利用该模型对串扰、对侧电位进行了模拟，从电池模型模拟出角膜尖端的电位最大。我们试图测量站立电位的绝对值来证实上述分析。实验测量了贴在闭上眼皮上的电极的最大电位值，测量了站立电位的绝对值，并将电池模型应用到眼球上，使我们能够分析EOG的详细特征。

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.
