背景：本研究旨在调查虹膜颜色对正常健康志愿者瞳孔光反射 (PLR) 的影响。方法：使用 Octopus 1-2-3 自动视野计对 50 名健康志愿者进行瞳孔视野检查。在30度视野内，对33个测试位置进行了四次调查。刺激参数为 Goldmann 尺寸 V（1.72 度）、强度 1632 cd/m(2)、刺激时间 200 ms、背景照明 0 cd/m(2) 和刺激间隔 3 s。研究的瞳孔测量参数包括初始瞳孔大小、振幅（瞳孔收缩幅度）、潜伏时间、收缩时间、PLR 前运动、收缩速度和再扩张速度。通过自变量蓝色和棕色虹膜的方差分析来研究瞳孔测量参数。结果：虹膜颜色（蓝色与棕色）的影响具有统计显着性（P
Background: This study was carried out to investigate the effect of iris color on the pupillary light reflex (PLR) in normal healthy volunteers.Methods: Pupil perimetry was performed on 50 healthy volunteers with the Octopus 1-2-3 automated perimeter. Within the 30-deg visual field, 33 test locations were investigated four times. Stimulus parameters were Goldmann size V (1.72 degrees), intensity 1632 cd/m(2), stimulus time 200 ms, background illumination 0 cd/m(2), and interstimulus interval 3 s. Pupillometric parameters studied were initial pupil size, amplitude (magnitude of pupillary contraction), latency time, contraction time, pre-PLR movement, contraction velocity, and redilation velocity. Pupillometric parameters were investigated by analysis of variance by the independent variables blue and brown irides.Results: Iris color (blue vs brown) influenced statistically significantly (P
