项目摘要

We developed an apparatus for measuring simultaneously the accommodation, vergence and pupil size of the human both eyes in binocular vision. And we tested this apparatus and tried to apply this to the clinical use. We reported the results as follows ;1 Development of the apparatusFor measurement of accommodation, we developed two small size Campbell type optometer and made it to small size two infrared optometer for both eyes. To measure in the natural viewing condition, the subject can see the real target binocularly through the infrared dichroic mirror, which passes the visible light but reflects infrared light. For measurement during vergence, this optometer have the mechanism which rotates it's optical parts around the each center of eye rotation of the both eyes.For detection of vergence, the potential meters are attached to the axis of the rotational bases on which optometer is fixed and the rotational angle are recorded.We can measure the diameters and area of both pupils by utilizing the video signal derived from TV camera for monitoring of the front of eyes.2 The simultaneous measurement of accommodation, vergence and pupil of both eyes.We confirmed that this apparatus recorded accommodation response, vergence and pupil size while the target moved along the middle line in front of the subject from a distance of 2m to 10 cm with dioptric stimulus of 0.25D/sec in room light of about 200 lux. In the myopic anisometropia eye of the refractive difference more than 1.5 D between both eyes, we measured the accommodations of both eyes and compared with the normal eyes when the real target move from 2m to 10cm with dioptric stimulus (0.25D/sec). From the recording, we found that the accommodation of both eyes are roughly equal but the amounts of accommodation were less than those of the normal eyes.

我们研制了一种仪器，可以同时测量人眼双眼的调节、聚光和瞳孔大小。我们测试了这个仪器，并试图将其应用于临床。我们报告的结果如下：1仪器的研制为了测量调节，我们研制了两个小尺寸的坎贝尔式验光仪，并将其研制成两个小尺寸的双眼红外验光仪。测量在自然观看条件下，被测者通过红外二向色镜可以双眼看到真实目标，红外二向色镜通过可见光而反射红外光。为了测量聚光过程，本验光仪的光学部件围绕双眼旋转的每个中心旋转。为了检测散度，将电势计固定在旋转基座的轴线上，并记录旋转角度。我们可以利用电视摄像机监控眼睛前部的视频信号来测量两个瞳孔的直径和面积同时测量双眼的调节、辐度和瞳孔。我们证实，在约200勒克斯的室内光线下，在0.25D/秒的屈光刺激下，当目标沿受试者前方中线移动2m至10 cm时，该装置记录了调节响应、收敛度和瞳孔大小。在双眼屈光差大于1.5 D的近视屈光参差眼中，我们测量了真实目标在屈光刺激（0.25D/秒）下从2m移动到10cm时双眼的调节，并与正常眼进行了比较。从记录中，我们发现两只眼睛的调节大致相等，但调节量比正常眼睛少。
