目的：对盲与低力流行病线索与抽样调查方法进行比较、评价。方法：１９９５年５月至７月，在云南省泸西县进行盲与低视力流行病学线索调查，与其１９８６年６月至１０月在云南省盲与低视力流病学抽样调查从人数、性别、地区、民族、职业及四种主要致盲原因等结果进行比较。结果：抽样调查患病率高于线索调查（Ｐ＜０．０１），两种调查均为女性高于男性；线索调查山区患病率低于抽样调查（Ｐ＜０．０１），坝区患病率也低于抽样调查（Ｐ＜０．０５）；两种调查汉族与彝族患病率无显著差异（Ｐ＜０．０５）；线索调查的农民患病率低于抽样调查（Ｐ＜０．０１）；抽样调查的白内障及角膜病患病率均高于线索调查（Ｐ＜０．０１）；而青光眼及眼外伤患病率相同，泸西县４０岁以下人群患病率仅为０．０３％。结论：两种调查方法结果比较，抽样调查的患病率、山区患病率、农民患病率及白内障和角膜病均高于线索调查，白内障是主要致盲原因，其次是角膜病。本地区开展防治盲工作，其重点可放在４０岁以上人群是可行的。
Objective: To compare and evaluate clues of blind and low-force epidemics and sampling methods. Methods: From May to July 1995, the clues of blindness and low vision epidemiology were investigated in Luxi County of Yunnan Province. Compared with the sample of blindness and low vision flu epidemics in Yunnan province from June to October in 1986, Gender, region, ethnicity, occupation and the four main causes of blindness. Results: The prevalence of sampling survey was higher than that of clues (P <0.01). Both surveys were higher in women than in men. The prevalence of census in mountainous area was lower than that of sampling survey (P <0.01) (P <0.05). The prevalence rates of Han and Yi in both surveys were not significantly different (P <0.05). The prevalence of peasants in the census survey was lower than that of the sample survey (P <0.05) .01). The prevalence of cataract and corneal disease were higher than clues (P <0.01) in the sample survey. The prevalence rates of glaucoma and ocular trauma were the same in Luzhou County, .03%. CONCLUSION: The results of the two surveys show that the prevalence of sampling, prevalence in mountainous areas, prevalence of peasants and cataracts and corneal diseases are all higher than clues. Cataracts are the main causes of blindness, followed by corneal diseases. The prevention and treatment of blind work in this region, the focus can be placed on people over the age of 40 is feasible.
