目的：调查唐山地区糖尿病低视力患者的发病现状，并对致病的危险因素进行探讨。

方法：采用抽样调查的方式选择2016-01/12唐山地区2 000例糖尿病居民为研究对象，对其进行视力检查，观察统计唐山地区糖尿病低视力的发生率。将糖尿病低视力患者纳入观察组，另取2倍病例数的糖尿病正常视力患者为对照组，采用Logistic 回归分析对两组患者相关病史资料进行调查，分析导致低视力危险因素。

结果：参与视力检查的2 000例糖尿病患者中，共有189例276眼患者视力低下，发生率为6.90%，其中单眼视力低下患者102例102眼(2.55%)，双眼视力低下87例174眼(4.35%)。经Logistic多因素回归分析显示，糖尿病患者的年龄、病程、视网膜病变程度是糖尿病患者视力低下的主要危险因素。

结论：唐山地区糖尿病患者并发视力低下的发生率较低，糖尿病患者的年龄、病程、视网膜病变是导致视力低下的主要原因。因此，加强对高龄、病程长、视网膜病变的糖尿病患者的视力检查，进行早期及时有效地防治，可减少对患者视力的损伤。

METHODS: A sampling survey was conducted to select 2 000 diabetic residents in Tangshan area from January to December 2016 to examine the incidence of diabetic low vision in Tangshan area. The diabetic patients with low vision included in the observation group, another 2 times the number of cases of diabetes with normal vision were selected as control group. Logistic regression was used to analyze the related history data of two groups of patients were investigated, to analyze the risk factors to low vision.

RESULTS: Of the 2000 diabetic patients involved in visual acuity examination, there were 189 patients(276 eyes)with poor vision, the incidence rate was 6.90%. Among them, 102 patients(102 eyes)with monocular vision deficit(2.55%), binocular vision was poor in 87 cases(174 eyes,4.35%). Logistic multivariate regression analysis showed that the age, course of disease and retinopathy of diabetes were the major risk factors of low vision in diabetic patients.

CONCLUSION: The incidence of low vision in diabetic patients in Tangshan area is low. The age, course of disease and retinopathy of diabetes are the main causes of low vision. Therefore, strengthening the retinopathy visual examination, early prevention and treatment, in elderly patients, and patients with long course of disease, can reduce the occurrence and development of low vision in patients with diabetes mellitus.
