甘肃省平凉市崆峒区人群盲和低视力现况调查

Status survey of blindness and low vision of population in Kongtong district of Pingliang city,Gansu Province

目的:探讨与了解甘肃省平凉市崆峒区人群盲与低视力的患病率及致病原因。方法:应用横断面研究的流行病学调查方法,以村(社区)为基础,采用随机整群抽样原则抽取6个乡镇2个街道办事处作为调查地点。采用世界卫生组织制定的盲与低视力标准,对全区按0.719%抽样比例抽取样本进行盲与低视力的流行病学调查。结果:检录3235例中,受检人数为2801例,受检率为86.58%,双眼盲21例,盲率为0.75%(男0.59%,女0.91%);双眼低视力125例,低视力患病率为4.46%(男3.73%,女5.16%),≥60岁以上盲与低视力患者的患病率明显增高。致盲病因前三位的眼病依次为白内障(47.62%)、角膜病(14.29%)、青光眼(14.29%)。结论:崆峒区人群中盲和低视力的眼病以白内障居首位,因此手术治疗白内障仍是今后防盲治盲工作的首要任务。

AIM：To explore and understand prevalence and causes of blindness and low vision of population in Kongtong district of Pingliang city, Gansu Province. METHODS： With application of cross-sectional study of the epidemiological investigation methods, and taking the village （community） as basis, six townships and two subdistrict offices were taken as the survey locations based on the principle of random cluster sampling. Useing the blind and low vision standards by World Health Organization, the region was sampled by 0. 719 percent sample proportion for the epidemiology survey of blindness and low vision. RESULTS： A total of 3235 people enrolled in, 2801 people received checkup, accounting for 86. 58%. 21 people were bilateral blindness, with blind rate of 0.75% （male 0. 59%, female 0. 91%）. 125 people were low vision, with prevalence of 4.46% （ male 3.73%, female 5. 16%）. Patients of age ≥ 60 years had significantly higher prevalence of blindness and low vision. The top three causes of blindness were cataract （47. 62%）, corneal diseases （14.29%）, and glaucoma （14.29%）. CONCLUSION：Cataract is in the first place of blindness and low vision eye disease in the population of Kongtong district, so the surgical treatment of cataract remains the primary task of the prevention of blindness in the future.
