免散瞳眼底照相在糖尿病视网膜病变筛查中的应用价值

Application value of non mydriatic fundus photography in the screening of diabetic retinopathy

目的:评价与裂隙灯眼底检查相比免散瞳眼底照相检出糖尿病视网膜病变的敏感性和特异性。方法:收治糖尿病患者664例,共1 328眼,行免散瞳眼底照相,并请眼科医师进行裂隙灯眼底检查。以眼科裂隙灯眼底诊断结果作为参考标准,评价免散瞳眼底照相的敏感性和特异性。比较两者在糖尿病视网膜病变检出率上的一致性。结果:眼底照相检出糖尿病视网膜病变的敏感性和特异性分别为85.1%和90.0%,Kappa值0.74。结论:免散瞳眼底照相为糖尿病视网膜病变的筛查提供了一种更简便、有效的检查手段,建议建立采用免散瞳眼底照相、以社区为基础的糖尿病视网膜病变筛查模式。

Objective：To evaluate the sensitivity and specificity to the detection of diabetic retinopathy by mydriatic fundus photography and slit lamp fundus examination.Methods：664 cases of diabetic patients and 1 328 eyes were selected.All patients underwent non mydriatic fundus photography,and asked the ophthalmologist to examine the fundus of the slit lamp,with slit lamp fundus diagnosis results as the reference standard.We evaluated the non mydriatic fundus photography sensitivity and specificity.We compared the consistency of the two in the detection rate of diabetic retinopathy.Results：The sensitivity and specificity of fundus photography in the detection of diabetic retinopathy were 85.1% and 90%,respectively,and Kappa value was 0.74.Conclusion：Non mydriatic fundus photography for diabetic retinopathy provides a simple and effective means of inspection.We propose to establish a community-based diabetic retinopathy screening model using mydriatic fundus photography.
