Large differences in failure rates for color vision screening have been reported among different regional groups. However, color vision deficiency prevalence in Korea has only been investigated within a small area of the country.
This study examines the prevalence of failing a color vision screening and its sex-related differences using a sample that is representative of the whole Korean population.
This population-based cross-sectional study evaluated 2686 subjects (age, 19 to 49 years) who participated in the sixth Korea National Health and Nutrition Examination Survey (2013). Color vision deficiency was assessed using the Hardy-Rand-Rittler (HRR) test by an ophthalmologist. According to standard criteria for the HRR, it classified each subject as color normal, protan, deutan, tritan, or unclassified color vision loss. All participants had comprehensive medical evaluations and ocular history taken.
The weighted overall prevalence of color vision deficiency in the Korean population was 3.9% (95% confidence interval, 3.0 to 5.4%). The prevalence of color vision deficiency was higher in male participants (6.5%) than in female participants (1.1%). Among all participants, deutan deficiency (2.5%) had a higher prevalence than did protan deficiency (0.4%). For male participants who failed the HRR screening, deutan-type deficiency was detected most often (64.2%), whereas an unclassified color vision deficiency type was the most common (52.9%) among female participants who failed the HRR screening. As expected, male participants were more likely to fail the HRR screening compared with female participants (prevalence ratio, 6.08; 95% confidence interval, 3.61 to 10.26).
This large population-based study of color vision deficiency among Koreans gives the most accurate estimate of failing a color vision screening test to date and provides useful information for planning adaptive strategies.
据报道，不同地区人群的色觉筛查失败率存在很大差异。然而，韩国色觉缺陷的患病率仅在该国的一个小区域内进行过调查。
本研究使用代表韩国全体人口的样本，调查色觉筛查失败的患病率及其性别差异。
这项基于人群的横断面研究评估了2686名年龄在19至49岁之间、参加第六次韩国国家健康与营养检查调查（2013年）的受试者。眼科医生使用哈迪-兰德-里特勒（HRR）测试评估色觉缺陷。根据HRR的标准标准，将每个受试者分类为色觉正常、红色盲、绿色盲、蓝色盲或未分类的色觉丧失。所有参与者都进行了全面的医学评估并记录了眼部病史。
韩国人群中色觉缺陷的加权总体患病率为3.9%（95%置信区间，3.0至5.4%）。男性参与者（6.5%）的色觉缺陷患病率高于女性参与者（1.1%）。在所有参与者中，绿色盲缺陷（2.5%）的患病率高于红色盲缺陷（0.4%）。在HRR筛查失败的男性参与者中，最常检测到绿色盲型缺陷（64.2%），而在HRR筛查失败的女性参与者中，未分类的色觉缺陷类型最为常见（52.9%）。正如预期的那样，与女性参与者相比，男性参与者更有可能在HRR筛查中失败（患病率比，6.08；95%置信区间，3.61至10.26）。
这项针对韩国人色觉缺陷的大规模基于人群的研究给出了迄今为止色觉筛查测试失败的最准确估计，并为制定适应性策略提供了有用信息。
