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.

眼电图（Electrooculogram，EOG）在眼科临床诊断中有着广泛的应用，但由于电极粘贴位置、电极种类和受检者等多种因素的影响，测量眼周电位的绝对值非常困难。因此，在临床试验中，测量由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。我们已经报道了，通过将电池模型应用于眼球，可以分析站立电位的变化。在这项研究中，EOG的各种特性的测量和模拟应用的电池模型的眼球。眼球的电池模型与实验结果吻合较好，但电极粘贴位置不同，本文应用电池模型分析了眼球线左右偏时的眼电图特征。利用该模型对串扰、对侧电位进行了仿真，从电池模型中模拟出角膜顶点电位最大。我们尝试测量了站立电位的绝对值，以证实上述分析。通过实验测量了贴在闭合眼睑上的电极的最大电位值，测量了其绝对值，并将电池模型应用于眼球，分析了眼电图的细节特征。
