In order to detect early defects of color vision caused by increased intraocular pressure, a computer graphics device and color monitor system were used to measure color contrast sensitivity. The system determines the threshold chrominance of a colored grating in which there is no change in luminance. The study included 13 control subjects aged 10 to 57 years and 19 patients with ocular hypertension or glaucoma aged 20 to 58 years. In the 13 eyes with visual field loss, color contrast sensitivity was profoundly reduced when the grating colors fell on a tritan color confusion line. In the eyes without visual field loss, tritan color contrast sensitivity was reduced to an average level considerably below the extreme limits of the control group. These results were compared with those of other color vision tests and diagnostic criteria for glaucoma. The findings suggest that among the tests used, color contrast sensitivity testing was able to discriminate most effectively between patients who had retinal damage and the normal population.
为了检测由眼压升高引起的早期色觉缺陷，使用计算机图形设备和彩色显示器系统来测量颜色对比敏感度。该系统确定亮度无变化的彩色光栅的阈值色度。该研究纳入了13名年龄在10至57岁的对照受试者以及19名年龄在20至58岁的高眼压症或青光眼患者。在13只存在视野缺损的眼睛中，当光栅颜色落在蓝黄色混淆线上时，颜色对比敏感度显著降低。在没有视野缺损的眼睛中，蓝黄色对比敏感度降低到明显低于对照组极限的平均水平。将这些结果与其他色觉测试结果以及青光眼诊断标准进行了比较。研究结果表明，在所使用的测试中，颜色对比敏感度测试能够最有效地区分视网膜受损患者和正常人群。
