数显补色照片体视仪的初步临床应用

PRELIMINARY CLINICAL APPLICATION OF DIGITAL COMPLEMENTARY COLOR ANAGLYPH STEREOTEST

介绍一种新设计的近距离立体视检测工具—数显补色照片体视仪。同时应用该仪器对１１３名学生进行近距离立体视锐度测定。结果表明：该仪器具有极高的精密度、正确度和精确度。该仪器用红一绿蓝颜色互补原理形成双眼视觉分离效果，从零点开始作逐渐增大的立体视锐度测定。其主要特点为：①可测的最小立体视锐度为１０秒。②可测的最大立体视锐度在１０００秒以上。③可连续性测量。④便于临床医师携带应用。

new instrument designed for near sterioacuity test一一digital complementary color anaglyph steriotest一一was introduced.The stereoacuities were examined by the stereotest on 113 students. The results of the study indicated that the instrument was of high precision,correctness and accuracy.The instrumnt produced a separate effect of the binocular vision on the principle of red一一green blue com-plementary color,and could be used to measure the stereoacuity continuously.The characteristics of the instrument were as follows :(1) The smallest stereoacuity measurable was 10 seconds.(2) The largest stereoacuity measurable was more than 1, 000 seconds.(3) A continuous measurement could be performed.(4)It was easy to be carried and used for clinicians.
