Routine ophthalmoscopy and fundoscopy of 673 individuals revealed 42 whose irides failed to dilate to a clinically useful degree within 25 to 30 min after the administration of drops of 1% mydracil. These individuals occurred with different frequency among the Aymara, Mestizo, and non-Aymara groups which made up the sample of examinees. The phenomenon was most common among the Aymara, less common among the Mestizos, and least common among the non-Aymara. Distribution of affected individuals within the three groups suggests that the trait is inherited.
对673人进行的常规检眼镜检查和眼底镜检查发现，42人在滴入1%的米得明滴眼液后25至30分钟内，虹膜未能扩张到临床有用的程度。这些个体在构成受检者样本的艾马拉人、混血儿和非艾马拉人群体中的出现频率不同。这种现象在艾马拉人中最为常见，在混血儿中较不常见，在非艾马拉人中最不常见。三组中受影响个体的分布表明该特征是可遗传的。
