To determine the equivalence of the ColorDx Military Research version (mColorDx) test and three printed pseudoisochromatic tests (HRR, Ishihara, and PIPIC) for color vision testing.
Participating in the study were 75 color-normals and 47 subjects with red-green color vision defects. Color vision was classified by an anomaloscope. The HRR (4(th) edition), Ishihara 38-plate edition, and PIPIC tests are printed color vision tests, whereas mColorDx test figures were displayed on a calibrated computer desktop monitor. All tests were repeated in about 1 wk.
The kappa level of agreement (κ) values with the anomaloscope for screening for each test was 0.96 or greater. The values were statistically identical. Specificity for each test was at least 0.99 and sensitivity was at least 0.95. The repeatability of the screening sections for all tests was very good with κ values greater than 0.95. Deutans tended to miss the tritan screening plates on the HRR and mColorDx tests. The Spearman rank correlation coefficients between the severity of the defect and anomaloscope range was moderate with r = 0.45 for the mColorDx and r = 0.6 for the HRR. Both the mColorDx and HRR had perfect agreement with the anomaloscope in classifying the defects as either protan or deutan.
The validity of the four tests for color vision screening was statistically identical; however, the HRR may be preferred because it had the highest sensitivity of 0.99, a specificity of 1.0, and a reasonable correlation between the severity rating of the defect and the anomaloscope range.
确定用于色觉测试的ColorDx军事研究版（mColorDx）测试与三种印刷的伪等色图测试（HRR、石原氏图和PIPIC）的等效性。
75名色觉正常者和47名红绿色觉缺陷受试者参与了该研究。通过检色镜对色觉进行分类。HRR（第4版）、石原氏38版和PIPIC测试为印刷色觉测试，而mColorDx测试图形显示在经过校准的计算机桌面显示器上。所有测试均在约1周后重复进行。
每种测试与检色镜用于筛查的kappa一致性水平（κ）值均为0.96或更高。这些值在统计学上相同。每种测试的特异性至少为0.99，敏感性至少为0.95。所有测试筛查部分的重复性都非常好，κ值大于0.95。在HRR和mColorDx测试中，绿色盲者往往会错过蓝色盲筛查图板。缺陷严重程度与检色镜范围之间的Spearman等级相关系数中等，mColorDx的r = 0.45，HRR的r = 0.6。mColorDx和HRR在将缺陷分类为红色盲或绿色盲方面与检色镜完全一致。
四种色觉筛查测试的有效性在统计学上相同；然而，HRR可能更受青睐，因为它具有最高的敏感性0.99、特异性1.0，并且缺陷严重程度评级与检色镜范围之间具有合理的相关性。
