A population-based study was conducted to determine the prevalence of color deficiencies in secondary-school students (ages 12-14) in Tehran.
A total of 2,058 students (1,136 males, 922 females) were examined with Ishihara pseudoisochromatic color plates.
In the study population, 97 cases of defective color vision were detected, including 93 males and 4 females. The affected individuals all had negative histories of previous systemic and ocular disease or chronic use of medications. The visual acuity was 20/20 and the fundus was normal in all affected students. Of the 93 cases of defective color vision in males (8.18%), 56 cases (4.93%) involved deuteranomaly, 13 (1.14%) protanomaly, 13 (1.14%) deuteranopia, and 11 (0.97%) protanopia. The four cases in females (0.43%) involved deuteranomaly in three cases (0.32%) and protanomaly in 1 case (0.11%). Deuteranopia and protanopia were not detected in females.
This is the first study to determine the prevalence of congenital color blindness in Iran. The results agree with reports of prevalence of congenital color blindness from Western Europe.
开展一项基于人群的研究，以确定德黑兰中学生（12至14岁）中色觉缺陷的患病率。
使用石原假同色图对总共2058名学生（1136名男性，922名女性）进行了检查。
在研究人群中，检测到97例色觉缺陷病例，其中包括93名男性和4名女性。所有受影响个体既往均无全身性和眼部疾病史或长期用药史。所有受影响学生的视力均为20/20，眼底正常。在93例男性色觉缺陷病例中（8.18%），56例（4.93%）为绿色盲，13例（1.14%）为红色盲，13例（1.14%）为绿色盲，11例（0.97%）为红色盲。女性中的4例（0.43%）包括3例绿色盲（0.32%）和1例红色盲（0.11%）。未在女性中检测到绿色盲和红色盲。
这是第一项确定伊朗先天性色盲患病率的研究。结果与西欧先天性色盲患病率的报告一致。
