CLINICAL STUDY FOR ACCOMMODATION

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 SPWhen 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.

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.
