目的了解新疆60岁及以上维吾尔族(下简称维族)农民盲患病率及主要致盲眼病。方法采用整群随机抽样的方法随机抽取了库车县年龄≥60岁的1 125名维吾尔族农民进行视力调查和眼部检查,按世界卫生组织盲目标准进行分类,并对所有针孔视力低于0.3者进行致盲原因分析。结果共有905名老年维族农民接受了检查,受检率为80.4%。双眼盲患病率为5.65%,双盲患病率随年龄的增长相应的增长,80岁组双盲患病率为60岁组的5.8倍,其差异有统计学意义(χ2=34.0,P<0.01)。男性双盲患病率略高于女性,其差异无统计学意义(χ2=2.1,P>0.05)。文盲组双盲患病率是非文盲组的2.37倍,其差异有统计学意义(χ2=8.1,P<0.05)。主要的致盲眼病为白内障、青光眼及眼底病变。结论库车县老年维族农民的双盲患病率为5.65%,主要的致盲眼病为白内障。提高白内障手术覆盖率是降低盲患病率的关键。
Objective To understand the prevalence of blindness and blindness in the population of Uighur aged 60 years and above in Xinjiang. Methods A total of 1 125 Uygur peasants aged 60 years and older in Kuche County were randomly selected for cluster analysis and eye examinations by random sampling method. According to the World Health Organization (WHO) blind criteria, all the acupuncture eyesight were lower than 0.3 were blinding reasons. Results A total of 905 elderly Uighur peasants were examined at a rate of 80.4%. The prevalence of binocular blindness was 5.65%. The prevalence of double-blindness increased with age. The prevalence of double-blindness in the 80-year-old group was 5.8 times that of the 60-year-old group (χ2 = 34.0, P <0.01). The prevalence of double-blind men was slightly higher than that of women, with no significant difference (χ2 = 2.1, P> 0.05). The illiteracy group double-blind prevalence rate was 2.37 times of non-illiteracy group, the difference was statistically significant (χ2 = 8.1, P <0.05). The main cause of blind eye disease is cataracts, glaucoma and fundus lesions. Conclusion The double-blind prevalence rate of older Uighur peasants in Kuqa County is 5.65%. The main cause of blindness is cataract. Improving cataract surgery coverage is the key to reducing the prevalence of blindness.
