A provisional, semiautomated version of a system for automated testing of the afferent pupillary reflex with perimetric methods under controlled conditions is described. The target projected onto the perimeter cupola is used as the stimulus for triggering the pupillary response. In a modification to the Octopus 201, the pupil is illuminated by two IR LED diodes, while the pupillary responses are recorded by the onboard IR sensitive TV camera built into the perimetric unit. Measurements of the pupillary area as a function of time and stimulus luminance have been performed and have resulted in consistent results. Here, one perimetric program, working with stimuli above the threshold for the afferent pupillary light reflex is described. The present setup works with system-specific software and standard hardware, the central data processing unit being a desk-top computer (IBM PC AT-03). The mating of an automated pupillary measuring unit to an automated perimeter may open the door for a more widespread evaluation of the value and the clinical application range of pupillary perimetry and may be of interest in other areas of visual and clinical psychophysics. The shortcomings of the present system, in particular insufficient temporal resolution and lack of full automation, are being removed at the present time.
本文描述了一种在可控条件下使用视野测量法自动测试传入性瞳孔反射的系统的临时半自动版本。投射到视野穹顶的目标用作触发瞳孔反应的刺激物。对Octopus 201进行了改进，用两个红外发光二极管照亮瞳孔，而瞳孔反应则由内置在视野测量单元中的机载红外敏感电视摄像机记录。已经对瞳孔面积作为时间和刺激亮度的函数进行了测量，并得到了一致的结果。这里描述了一个视野测量程序，该程序使用高于传入性瞳孔光反射阈值的刺激。目前的设置使用特定系统的软件和标准硬件，中央数据处理单元是一台台式计算机（IBM PC AT-03）。将自动瞳孔测量单元与自动视野计配合使用，可能为更广泛地评估瞳孔视野测量的价值和临床应用范围打开大门，并且可能在视觉和临床心理物理学的其他领域引起关注。目前正在消除本系统的缺点，特别是时间分辨率不足和缺乏完全自动化的问题。
