The main purpose of this study was to produce reliable, color assessment outcomes to examine the extent to which single and multi‐test protocols in use meet current clinical and occupational needs. The latter include the detection of small changes in chromatic sensitivity as the earliest signs of retinal and/or systemic disease, and the need to assess the class of color vision in congenital deficiency and to quantify severity of loss. Color vision was assessed using Ishihara (IH), Farnsworth Munsell D‐15, City University (CU, 2nd ed.) and Holmes‐Wright type A (HW‐A) lantern tests. All subjects also carried out Colour Assessment and Diagnosis and Nagel anomaloscope tests. The sample included 350 normal trichromats, 1012 deutans and 465 protans (age 31.1 ± 12.4, range 10‐65 years). The results reveal the trade‐off between sensitivity and specificity, depending on the number of errors accepted as a pass on the IH test. The D‐15 and CU tests pass all normals and almost 50% of subjects with color vision deficiency. The HW‐A lantern passes all normals, 22% of deutans and 1% of protans. The multi‐test protocols designed to identify protans and to pass only subjects with mild color loss, pass over 50% of protans and deutans. Many of the subjects who fail exhibit less severe loss of color vision than others who pass. When high sensitivity for detection of congenital deficiency is achieved, single‐test protocols fail many normal trichromats. Multi‐test protocols produce large variability and fail to achieve desired aims.

色彩视觉评估-2:使用单一测试和多重测试方案的色彩评估结果

这项研究的主要目的是产生可靠的颜色评估结果,以检查使用的单项测试和多项测试方案在多大程度上满足当前的临床和职业需求。后者包括检测作为视网膜和/或全身性疾病的最早迹象的色敏度的微小变化,以及需要评估先天性缺乏症中色觉的类别并量化损失的严重性。使用Ishihara(IH),Farnsworth Munsell D-15,城市大学(CU,第二版)和Holmes-Wright A型(HW-A)提灯测试评估色觉。所有受试者还进行了颜色评估和诊断以及Nagel肛门镜检查。样本包括350个正常三色性,1012个氘代和465个质子(年龄31.1±12.4,范围10-65岁)。结果揭示了敏感性和特异性之间的权衡,取决于通过IH测试的合格错误数量。D-15和CU测试通过了所有正常人,几乎50%的有色觉缺陷的受试者通过了测试。HW-A灯笼可以通过所有常态,22%的犹太人和1%的protans。旨在识别质子并仅使色泽较轻的受试者通过的多重测试规程,使50%以上的质子和deutans通过。与不及格的人相比,许多不及格的人的色觉丧失没有那么严重。当达到对先天性缺陷检测的高灵敏度时,单次检测方案会使许多正常的三色性检测失败。多重测试协议会产生很大的差异,无法达到预期的目标。HW-A灯笼可以通过所有常态,22%的犹太人和1%的protans。旨在鉴定质子并仅使色泽较轻的受试者通过的多重测试规程,使50%以上的质子和deutans通过。与不及格的人相比,许多不及格的人的色觉丧失没有那么严重。当达到对先天性缺陷检测的高灵敏度时,单次检测方案会使许多正常的三色性检测失败。多重测试协议会产生很大的差异,无法达到预期的目标。HW-A灯笼可以通过所有常态,22%的犹太人和1%的protans。旨在鉴定质子并仅使色泽较轻的受试者通过的多重测试规程,使50%以上的质子和deutans通过。与不及格的人相比,许多不及格的人的色觉丧失没有那么严重。当达到对先天性缺陷检测的高灵敏度时,单次检测方案会使许多正常的三色性检测失败。多重测试协议会产生很大的差异,无法达到预期的目标。当达到对先天性缺陷检测的高灵敏度时,单次检测方案会使许多正常的三色性检测失败。多重测试协议会产生很大的差异,无法达到预期的目标。当达到对先天性缺陷检测的高灵敏度时,单次检测方案会使许多正常的三色性检测失败。多重测试协议会产生很大的差异,无法达到预期的目标。
