项目摘要

In clinical test of accommodative function, the points becoming problem are method of evaluation of the function and disagreement about significance of reaction form. In the former, a quantity of time factor, situation of clear-vision and amplitude of accommodative reaction is discussed in the state that essence of evaluation object is not understood by each examiners.The accommodation time measurement device which asked NIDEK company for trial manufacture can grasp connection with time element and clear-vision of accommodative function. We could understand that analysis of quantity of so-called amplitude of accommodative reaction was possible as a result of having carried out this device and comparison of infrared optometer. As a result, we expected rapid accommodative reaction of 0.5 seconds or there-abouts, and the course to get clear-vision in normally persons were made, and it was supposed that it after reaction course was controlled by psychogenic factors which let the clear-vision last. And, in comparison with accommodo-polyrecorder which was one of the accommodative function measurement model of machines that was typical as now, shortening tendency of accommodation time was recognized.A tendency reduced recognized one thing as a result of we accompanied accommodative reaction and used MEM (maximum entropy method) accommodative fluctuation observed, ・・・and having analyzed it as the thing and SP (spectral power) which it became in the element which increased SP blurred-vision of targets approached resting state of accommodation. When MEM analyzes sourse of accommodative fluctuation than these fact, it is tha method that is very significant, and it is expected an opportunity used in future increase.

在临床功能测定中，存在的问题主要是功能评价方法和反应形式意义的不一致。前者是在各检查者不了解评价对象的实质的情况下，讨论了时间因素、视物清晰情况和反应幅度的数量，委托NIDEK公司试制的适应时间测量装置，能掌握与时间因素和视物清晰功能的关系。我们可以理解，由于实施了该装置和红外视力计的比较，可以分析所谓的反射反应振幅的量。结果，我们预期0.5秒左右的快速反应，以及正常人获得清晰视力的过程，并推测其反应后过程受心理因素控制，使清晰视力得以持续。并且，与目前典型的机器的反射功能测量模型之一的多功能记录仪相比，认识到调节时间的缩短趋势，由于我们伴随反射反应并使用MEM，认识到一件事的趋势减少（最大熵法）观测到的涨落，···并分析了它作为增加SP模糊目标的因素中的事物和SP（光谱功率）接近静息调节状态。当MEM分析这些事实之外的波动来源时，这种方法是非常有意义的，并且预计这是在未来增长中使用的机会。
