【摘要】：目的：了解云南省大理50岁及以上农村白族人口的屈光不正的患病率,并分析其影响因素。方法：我们把大理古城附近所有白族人口集中的行政村划分为基本抽样单位,应用整群抽样的方法从中抽取调查点。对纳入调查人群进行视力,验光,眼压测量,AB超,裂隙灯检查眼前节,直接检眼镜及前置镜行眼底检查等初步筛查,并填写调查问卷表。屈光不正数据用SE(等效球镜度)表示,SE-0.50D定义为近视,SE+0.50D定义为远视,柱镜度数+0.75D定义为散光。结果：共有2133人接受检查,受检率达77.8%。其中63.9%是女性,36.1%为男性。参与者的平均年龄是64.5±8.9岁(50.1-91.7岁)。近视的患病率是21.5%(以下均以右眼为例),男性23.8%,女性20.1%。从50-80岁近视的患病率随年龄的增加呈增加趋势,这可以部分的归因于白内障的患病率随着年龄的增加而增加引起的。在一个logistic多因素分析中,年龄,白内障和近视是相关的。远视的患病率是16.0%(95%CI,14.5%-17.6%),女性为17.2%,男性13.9%。远视的患病率随着年龄的增加呈“⌒”型,其峰值在70-75岁年龄段。散光的患病率为27.2%(95%CI,24.8%-29.5%)。屈光参差的患病率是8.0%(95%CI,6.9%-9.2%)。结论：大约五分之一的50岁及以上的大理农村白族人口患有近视。比较以前相似年龄段的调查报告,近视,远视,散光和屈光参差的患病率都更低。影响屈光不正的有统计学意义的相关因素分别是白内障和年龄。在老年人中屈光不正是一个重要问题,且患病率随年龄变化而变化。
[Abstract]:Objective: to investigate the prevalence of ametropia in rural Bai population aged 50 and above in Dali, Yunnan Province, and to analyze its influencing factors. Methods: all administrative villages with concentrated Bai population near Dali ancient city were divided into basic sampling units. Cluster sampling was used to extract the investigation points from them. Visual acuity, optometry, intraocular pressure measurement and AB supersonic examination, slit lamp examination of anterior segment, direct ophthalmoscope and antecedent ophthalmoscope were carried out and the questionnaire was completed. SE-0.50D is defined as hyperopia by SE0.50D and astigmatism is defined as 0.75D by cylindrical lens. Results: a total of 2133 people were examined, and the rate of examination was 77.8%. Among them, 63.9% were female and 36.1% were male. The average age of participants was 64.5 卤8.9 years old and 50.1-91.7 years old. The prevalence of myopia was 21.5. From 50 to 80 years old, the prevalence of myopia increases with the increase of age, which can be partly attributed to the increase of the prevalence of cataract with the increase of age. Age, cataract and myopia were associated in a logistic multivariate analysis. The prevalence of hyperopia was 16.0 and 95%, and 14.5- 17.6cm, 17.2 for females and 13.9g for males. The prevalence of hyperopia increased with age, and its peak value was 70-75 years old. The prevalence of astigmatism was 27.2and 95%. The prevalence of anisometropia was 8.0 and 95%. Conclusion: about 1/5 of the Bai people aged 50 and over in Dali rural area suffer from myopia. The prevalence of myopia, hyperopia, astigmatism and anisometropia was lower than previous studies of similar age groups. Cataract and age were the statistically significant factors affecting ametropia. Refraction is not an important problem in the elderly, and prevalence varies with age.
