To follow the refraction values in an indigenous population group over the course of the past 50 years.
Case records from a population investigation carried out in Ammasalik, East Greeland, by Erik Skeller in 1950 were studied initially, a total of 1123 eyes were examined by sciascopy and 244 eyes could be followed sufficiently until about 1990-94.
The mean refraction was initially +0.08 D, while at the last examination the mean had increased to +0.69 D. Initially, there was no myopia, defined as at least -1.5 D, and at follow-up it was a maximum of 1%, and presumably due to immature cataract. A tendency to myopia (< -1.5 D) was found initially in 36%, but in only 22% at follow-up.
The myopinizing factor in East Greenland has not affected persons born prior to 1942, even if they had a tendency to myopia (< -1.5 D).
追踪一个本土人群在过去50年中的屈光值变化。
最初研究了埃里克·斯凯勒于1950年在东格陵兰的阿玛萨利克进行的一项人群调查的病例记录，共有1123只眼睛接受了检眼镜检查，其中244只眼睛能够被充分追踪至大约1990 - 1994年。
最初的平均屈光为+0.08 D，而在最后一次检查时，平均值已增至+0.69 D。最初，不存在近视（定义为至少-1.5 D），随访时近视率最高为1%，可能是由于未成熟白内障所致。最初发现有近视倾向（<-1.5 D）的比例为36%，但随访时仅为22%。
东格陵兰的近视化因素并未影响1942年之前出生的人，即使他们有近视倾向（<-1.5 D）。
