Previous research has shown exposure-related increases in the prevalence of acquired color vision deficits among printers. We administered the Lanthony D-15 desaturated test of color vision to 82 print shop workers. Two tests of cognitive function, Trails A and B and the Symbol Digit Modalities Test, were also administered. Personal air sampling indicated that current exposure to organic solvents was highest among printers and lowest among bindery workers. In contrast to previous studies, the age-adjusted quantitative Lanthony D-15 desaturated test error scores did not differ significantly between exposure groups, and the proportion of subjects with > or = 1 error was greater in the lower-exposure, rather than higher-exposure, groups (P = .03). Of note, the proportion of subjects with > or = 2 errors did not differ significantly between groups (P = .24). Cognitive tests showed no significant association with exposure. These results are discussed in the context of methodological issues related to lighting sources, reliability of test results, and establishment of criteria for identifying deficits.
先前的研究表明，接触相关因素会使印刷工人后天性色觉缺陷的患病率增加。我们对82名印刷厂工人进行了兰托尼D-15色觉去饱和测试。还进行了两项认知功能测试，即A和B连线测验以及符号数字模式测验。个人空气采样表明，目前有机溶剂暴露在印刷工人中最高，在装订工人中最低。与先前的研究不同，经年龄调整后的定量兰托尼D-15色觉去饱和测试误差分数在暴露组之间没有显著差异，并且错误数≥1的受试者比例在低暴露组而非高暴露组中更高（P = 0.03）。值得注意的是，错误数≥2的受试者比例在组间没有显著差异（P = 0.24）。认知测试显示与暴露没有显著关联。将在与光源、测试结果可靠性以及确定缺陷标准相关的方法学问题的背景下讨论这些结果。
