目的调查新疆库车县年龄≥40岁维吾尔族农民盲与低视力的患病率及主要致盲原因。方法采用整群随机抽样方法,按世界卫生组织盲目分类标准对随机抽取的新疆库车县2955名维吾尔族农民进行视力调查,对针孔镜下视力低于0.3者进行眼部检查并做主要致盲原因诊断。结果共录入3692人,实际受检2955人,受检率为80.0%。其中双盲患病率为2.1%,双眼低视力患病率为9.9%。60岁组双盲患病率是40岁组的13.5倍,差异有统计学意义(P<0.01);男性双盲患病率是女性的1.4倍,差异无统计学意义(P>0.05);文盲组双盲患病率是非文盲组的4.5倍,差异有统计学意义(P<0.01)。结论新疆库车县年龄≥40岁维吾尔族农民盲及低视力患病率高于国内部分地区,首要致盲眼病仍为白内障,故降低白内障患病率是该地区防盲治盲的关键。
Objective To investigate the prevalence and main causes of blindness and low vision of Uygur peasants aged> 40 years in Kuqa County of Xinjiang Autonomous Region. Methods A total of 2955 Uygur peasants from Kuche County of Xinjiang were randomly selected by cluster random sampling method according to the World Health Organization (WHO) Blind Classification Standard. The eye examinations were performed under the pinhole microscope with visual acuity of less than 0.3, Blind cause diagnosis. Results included a total of 3692 people, the actual test 2955 people, the test rate was 80.0%. The prevalence of double-blindness was 2.1%, and the prevalence of binocular low vision was 9.9%. The prevalence of double - blindness in 60 years old group was 13.5 times that in 40 years old group, the difference was statistically significant (P <0.01). The prevalence of double - blind men in male was 1.4 times that of female (P> 0.05). The illiteracy group double-blind prevalence rate is 4.5 times of non-illiteracy group, the difference was statistically significant (P <0.01). Conclusion The prevalence of blindness and low vision of Uyghur peasants aged> 40 years old in Kuqa County of Xinjiang is higher than that in some parts of China. The primary cause of blind eye is still cataract. Therefore, reducing the prevalence of cataract is the key to prevent blindness in this area.
