BACKGROUND
Chromatic contrast may affect stereopsis. Daltonism is a common color deficiency in which the colors red and green are incorrectly detected. The aim of this study was to evaluate the stereoacuity of color-defective individuals presented with color symbols that they see defectively.
METHODS
Ten students diagnosed with daltonism and 10 students with normal color vision were recruited. A stereopsis test system using a phoropter and two 4K smartphones was used. Contour-based graphs and random-dot graphs with black versus white and red versus green patterns were used as test symbols. The Wilcoxon signed rank test was used to test the difference between groups.
RESULTS
No significant difference in stereoacuity was found between contour-based and random-dot graphs within both daltonism cohort and normal color vision cohort ( > 0.05). A significant difference in stereoacuity was found between the black-white (=0.005) and red-green (=0.007) graphs for the daltonism cohort, while no significant difference in stereoacuity was found for the normal color vision cohort ( > 0.05).
CONCLUSION
Chromatic contrast is an influential factor for stereopsis measurement in individuals with color deficiency.
背景
颜色对比度可能会影响立体视觉。红绿色盲是一种常见的色觉缺陷，其中红色和绿色被错误地识别。本研究的目的是评估色觉缺陷个体在看到有缺陷的颜色符号时的立体视锐度。
方法
招募了10名被诊断为红绿色盲的学生和10名色觉正常的学生。使用了一种使用综合验光仪和两部4K智能手机的立体视觉测试系统。以黑色与白色以及红色与绿色图案的基于轮廓的图表和随机点图表用作测试符号。采用Wilcoxon符号秩检验来检验组间差异。
结果
在红绿色盲组和色觉正常组中，基于轮廓的图表和随机点图表之间的立体视锐度均未发现显著差异（>0.05）。红绿色盲组在黑白（=0.005）和红绿（=0.007）图表之间的立体视锐度存在显著差异，而色觉正常组的立体视锐度未发现显著差异（>0.05）。
结论
颜色对比度是影响色觉缺陷个体立体视觉测量的一个因素。
