目的：本研究的目的是评估数字颜色传感在使用数字照片量化虹膜颜色方面的实用性，并确定性别或虹膜颜色是否影响暗适应瞳孔直径（DAPD）。方法：年龄在18-80岁之间（N=263）的无眼部疾病受试者在1勒克斯暗适应2分钟后使用NeurOptics瞳孔计测量右侧DAPD。拍摄了虹膜的高分辨率数字裂隙灯照片，并将虹膜颜色主观分类为蓝色、蓝绿色、绿棕色、浅棕色或深棕色。使用Minolta TV Color Analyzer II使用Commission Internationale de l 'Eclairage颜色描述系统在屏幕上客观测量数字照片。进行回归分析，以确定主观虹膜颜色，国际委员会的测量，和DAPD之间的相关性。结果：性别和虹膜颜色对DAPD没有影响。美能达电视色彩分析仪可以区分所有蓝色眼睛（蓝色和蓝绿色）和所有棕色眼睛（浅色和深色），但无法区分蓝色色调或棕色色调。绿棕色虹膜没有独特的色彩特性，无法使用我们的数字颜色分析技术与其他颜色区分开来。美能达设备是简单而有效的use.Conclusions：相反，长期持有的信念，女性患者和蓝眼睛的患者没有较大的DAPD。数字颜色传感是一种客观描述虹膜颜色的有效技术。
Purpose: The aims of this study were to assess the utility of digital color sensing to quantify iris color using digital photographs and to determine whether gender or iris color affects the dark-adapted pupil diameter (DAPD).Methods: Subjects aged 18-80 years (N=263) with no eye disease had their right DAPD measured after 2 min of dark adaptation at 1 lux using the NeurOptics pupillometer. A high-resolution digital slit lamp photograph of the iris was taken, and iris color was subjectively classified as blue, blue-green, green-brown, light brown, or dark brown. The digital photographs were objectively measured on-screen with the Minolta TV Color Analyzer II using the Commission Internationale de l'Eclairage system of color description. Regression analyses were performed to identify correlations between subjective iris color, Commission Internationale de l'Eclairage measurements, and DAPD.Results: Gender and iris color had no effect on the DAPD. The Minolta TV Color Analyzer could discriminate all blue eyes (blue and blue-green) from all brown eyes (light and dark) but could not distinguish between shades of blue or shades of brown. Green-brown irises had no unique chromatic properties and could not be distinguished from other colors using our technique of digital color analysis. The Minolta device was simple and efficient to use.Conclusions: Contrary to long-held beliefs, female patients and blue-eyed patients do not have larger DAPD. Digital color sensing is a useful technique for objectively describing iris color.
