盲目及低视力是各种眼科疾病的后果,摸清造成盲目及低视力的眼病、病因,可制定出切实可行的予防措施。我们于1984年对青海互助土族40岁以上农民进行了盲目及低视力调查。我们共检查互助土族世居40岁以上农民437人,874眼,其中男性217人,女性220人。年龄最小者40岁,最大者83岁,40岁至60岁152人,57岁以上285人570眼。一、盲目及低视力标准采用1973年,W.H.O 制定的盲目及低视力标准,采用国际标准视力表进行检查。我们所检查的437人中属于低视力者74人。其中双眼低视力31人,单眼低视力43人,男性36人,女性38人。按低视力数计算,双眼低视力占受检总人数的7.09%,单眼低视力占9.84%。
Blind and low vision are the consequences of various eye diseases, find out blind and low vision of eye diseases, causes, can develop practical preventive measures. In 1984, we carried out blind and low-vision surveys on the peasants in Tu-Hu-Tu-Tu ethnic group over 40 years of age in Qinghai Province. We examined a total of 437 peasants who were over 40 years old and 874 eyes of them, 217 were males and 220 were females. The youngest person is 40 years old, the largest is 83 years old, the age is 40 to 60 years old 152 people, and the 57 years old is 285 people 570 eyes.

Of the 437 people we examined, 74 were those with low vision. Among them, the eyes of low vision 31 people, monocular low vision 43 people, 36 males and 38 females.
