The Farnsworth D15 (FR-D15) color vision test is generally used to determine whether individuals with color vision defects have good color discrimination to perform their jobs safely. The Waggoner computerized color vision test D15 (WC-D15) is a computerized version of the FR-D15 test. This study aimed to evaluate the color differences vectors analyses (CDV) quantitative scoring in clinical practice using the FR-D15 and WC-D15 color vision tests. Fifty-nine individuals with congenital red-green color vision deficiency participated in this study. All participants were screened with the Ishihara, Waggoner Pseudoisochromatic plates, and City University Tests. Participants also completed FR-D15 and WC-D15 tests. The number of crossings, and CDV indices, including the confusion index, total error score, specificity index, and angle were assessed. There were significant correlations between the number of crossings and each of the CDV parameters. Results of both D15 tests showed that defects classified by confusion angles improve with an increase in crossings. The correct diagnosis rate improved when the criterion of failure was relaxed compared to the generally accepted criteria of ≥2. A CDV angle of either 0° or −3° accurately classifies defects as protan or deutan. Quantitative measurements of the FR-D15 and WC-D15 color vision tests showed good results in detecting color vision deficiency and diagnosing the type of defect. The CDV parameters positively correlated with the traditional evaluation of the defect's presence by counting the crossings. It is more accurate for clinicians to interpret their results using the CDV parameters.

临床实践中 Farnsworth D15 和 Wagoner 计算机化 D15 色觉测试的定量评分方法

Farnsworth D15 (FR-D15) 色觉测试通常用于确定具有色觉缺陷的个人是否具有良好的颜色辨别能力以安全地执行工作。Wagoner 计算机化色觉测试 D15 (WC-D15) 是 FR-D15 测试的计算机化版本。本研究旨在使用 FR-D15 和 WC-D15 色觉测试评估临床实践中的色差矢量分析 (CDV) 定量评分。59 名先天性红绿色视力缺陷患者参与了这项研究。所有参与者都接受了 Ishihara、Wagoner Pseudoisochromatic 板和 City University Tests 的筛选。参与者还完成了 FR-D15 和 WC-D15 测试。评估交叉数和 CDV 指数，包括混淆指数、总错误评分、特异性指数和角度。交叉次数与每个 CDV 参数之间存在显着相关性。两个 D15 测试的结果表明，按混淆角分类的缺陷随着交叉点的增加而改善。与公认的≥2 标准相比，放宽失败标准时正确诊断率提高。0° 或 -3° 的 CDV 角准确地将缺陷分类为 protan 或 deutan。FR-D15 和 WC-D15 色觉测试的定量测量在检测色觉缺陷和诊断缺陷类型方面显示出良好的结果。CDV 参数与通过计数交叉点对缺陷存在的传统评估呈正相关。临床医生使用 CDV 参数来解释他们的结果会更准确。
