我们于1986年5月至12月在贵州惠水、镇宁、黔西、咸宁。纳雍五个县进行盲目和低视力流行病学调查。盲目及低视力标准,采用1973年W·H·O制定的最佳矫正视力小于0.05为盲,小于0.3、大于或等于0.05为低视力。调查结果如下: 五个县总人口为2,643,080人,抽样调查25个流调点共18,707人。受检人数18,387人,36,774眼。其中男性9,296人,18,592眼,女性9,091人,18,182眼。视力≥0.3占受检眼数的93.76％,低视力眼数占0.95％,盲眼数占0.90％。能固视或追随目标者占4.34％,未确定或未指明者占0.04％。盲目及低视力患病率:共查出单眼盲164人,其患病率为0.89％。双眼盲84人,患病率0.46％。单眼低视力135人,患病率0.73％。双眼低视力107人,患病率0.58％。以样本推论总体,预测五县约有单眼盲患者2.3万人、双眼盲1.2万人、单眼低视力1.9万人、双眼低
We in May 1986 to December in Guizhou Huishui, Zhenning, Qianxi, Xianning. Nayong five counties for blind and low vision epidemiological investigation. Blind and low vision standards, using W · H · O in 1973 to develop the best corrected visual acuity of less than 0.05 is blind, less than 0.3, greater than or equal to 0.05 for low vision. The survey results are as follows: The total population of the five counties was 2,643,080, with a sample survey of 25 streams and a total of 18,707 people. The number of subjects was 18,387, 36,774 eyes. Of these, 9,296 were males, 18,592 were females, 9,091 were females and 18,182 were eyes. Visual acuity ≥0.3 accounted for 93.76% of the number of eye examination, low vision eye accounted for 0.95%, the number of blind 0.90%. 4.34% were able to fix or follow the target, 0.04% were unspecified or unspecified. Blind and low vision prevalence: a total of 164 people were detected monocular blind, the prevalence was 0.89%. Blind eyes 84 people, the prevalence of 0.46%. Monocular low vision 135 people, the prevalence of 0.73%. Eyes low vision 107 people, the prevalence of 0.58%. To corroborate the population as a whole, about 15,000 monocular blind patients in five counties, 12,000 eyes blind, monocular low vision 19,000 people, low eyes
