METHODS: Patients with congenital red-green color vision deficiency and age- and gender-matched healthy controls were included in this cross-sectional comparative study. Contrast sensitivity measurements were taken from all subjects in 4 different conditions; binocular mesopic-without glare, mesopic-with glare, photopic-without glare, photopic-with glare, and the results were compared.
RESULTS: Twenty one patients with color vision deficiency (13 deuteranopic, 8 protanopic) and 22 age- and gender-matched healthy controls were included in the study. The mean age was 35.2 ± 13.5 years in the protan group, 30.6 ± 7.7 years in the deutan group, 32.0 ± 8.8 years in the control group, and there was no significant difference in age between the groups (P > 0.05). The mean mesopic and photopic contrast sensitivity values of the groups at all spatial frequencies (1.5, 3, 6, 12, 18 cpd) were not statistically significant when evaluated by the multifactor repeated measures test of ANOVA to evaluate the effect of light conditions (with and without glare) (P > .05).
CONCLUSIONS: Mesopic and photopic contrast sensitivity values of patients with congenital red-green color vision deficiency were similar to healthy controls regarding with and without glare conditions.
方法:这项横断面比较研究包括先天性红绿色视力缺陷患者和年龄和性别匹配的健康对照。在4种不同的条件下,对所有受试者进行了对比敏感度测量;双眼近视眼-无眩光,mesopic-withglarge,明视-无眩光,明视-眩光,并对结果进行了比较。
结果:21例色觉缺陷患者(13例,研究中包括8个原型)和22个年龄和性别匹配的健康对照。protan组的平均年龄为35.2±13.5岁,Deutan组30.6±7.7年,对照组32.0±8.8岁,组间年龄差异无统计学意义(P>0.05)。当通过ANOVA的多因素重复测量测试来评估光条件(有和没有眩光)的影响时,在所有空间频率(1.5、3、6、12、18cpd)下各组的平均中视和明视对比敏感度值没有统计学意义(P>.05)。
结论:先天性红绿色视力缺陷患者的中视和明视对比敏感度值与健康对照在有无眩光条件下相似。
