【摘要】： 目的了解青海省泽库县40岁及以上世居藏族人群眼底病的患病率,盲以及低视力状况,并且与国内已有调查结果相比较。方法于2006年8月至12月间,采用整群随机抽样方法在青海省泽库县2个镇5个乡的世居藏族人群中抽取2229人,使用间接检眼镜等对该县40岁及其以上世居藏族人群进行眼底病的流行病学进行抽样调查。在进行正式调查之前先行预调查,并将最终调查结果与国内已有的相关流行病学资料进行比较。结果本次调查活动实际接受检查的人数为2229人,其中男性受检者1209人,占总受检人群的2.89%,女性受检者1090人,占受检人群的3.04%,男女的性别比例为1:0.84。接受检查的目标人群的最小年龄为40岁,最大年龄为88岁,受检者的文化程度以文盲为主。检查出各种眼底异常206只眼,总眼底异常患病率为9.20%,其中以老年黄斑变性(AMD)和视神经萎缩最为多见,AMD 112只眼,占总眼底异常的54.37%,占总受检人群的5.02%,视神经萎缩32只眼,占总眼底异常15.53%,占受检人群的1.44%。眼底异常的盲率随年龄增加而增加,而与性别无关。结论本次眼底病流行病学调查结果显示青海省泽库县40岁及以上世居藏族人群眼底异常高于内地,眼底异常的盲率随年龄增加而增加,与性别无关;老年黄斑变性和视神经萎缩为主要致盲眼底病;高海拔,缺氧,饮食中缺乏维生素与慢性光损伤是高原地区眼底病高发病率的可能危险因素。
[Abstract]:Objective to investigate the prevalence, blindness and low vision of fundus disease in Tibetan population aged 40 and above in Zecu County, Qinghai Province, and to compare the results with those in China.Methods from August to December, 2006, a cluster random sampling method was used to select 2229 native Tibetans from 2 towns and 5 townships in Zecu County, Qinghai Province.Indirect ophthalmoscope was used to investigate the epidemiology of fundus disease in Tibetan population aged 40 and above.The final survey results are compared with the relevant epidemiological data available in China.Results the actual number of people examined in this investigation was 2229, of whom 1209 were male, accounting for 2.89 of the total population, 1090 were female and 3.04 were female, the sex ratio of male to female was 1: 0.84.The minimum age of the target population was 40 and the maximum age was 88. The literacy of the subjects was mainly illiterate.206 eyes with various fundus abnormalities were detected. The prevalence rate of total fundus abnormality was 9.20. AMD was the most common in senile macular degeneration and optic atrophy, accounting for 54.37% of total fundus abnormalities, 5.02% of total tested population and 32 eyes of optic atrophy.Accounting for the total fundus anomaly 15.53, accounting for 1.44 of the population examined.The blindness rate of fundus abnormalities increased with age, but not with sex.Conclusion the results of the epidemiological investigation of fundus disease showed that the ocular fundus abnormality of Tibetan population aged 40 and above was higher than that of the inland area, and the blindness rate of ocular fundus abnormality increased with the increase of age, and had no relation with sex.Senile macular degeneration and optic atrophy were the main causes of blindness, high altitude, hypoxia, vitamin deficiency in diet and chronic light injury were the possible risk factors of high incidence of fundus disease in high altitude.
