By the same operator with non-mydriatic fundus photography, fundus photography and 7 range fundus fluorescein angiography(FFA)after mydriasis were taken. Taking the international clinical classification of diabetic retinopathy(DR)as the standard, the above three examinations were review, grade and record by the same physician by blind method. The fundus fluorescein angiography as the gold standard, the other two results were compared to detect the sensitivity, specificity, Youden index, Kappa value of the two for DR with different grade.<p>RESULTS: There was 70.0% eyes diagnosed as diabetic retinopathy after screened by fundus angiography, 66.7% by post-mydriatic fundus photography, 65.0% by non-mydriatic fundus photography. The grading results of diabetic retinopathy screened by different methods were basically consistent, with no significant difference(<i>P</i>>0.05). When screening for diabetic retinopathy of different degrees, the sensitivity and specificity of the non-mydriatic group were 92.9% and 90.3%, respectively. There was no significant difference between the results of the non-mydriatic group and the non-mydriatic group. Compared with the gold standard group(FFA), the Youden index(83.14%)was close to 1, with high reliability; Kappa=0.81, and the validation was consistent. When screening for moderately nonproliferative diabetic retinopathy, the sensitivity and specificity of non-mydriatic fundus photography were 90.6% and 95.5%; there was no significant difference between the results of non-mydriatic and the results of fundus photography after mydriasis. Compared to the gold standard group, the Youden index was 86.09%, the reliability is high, Kappa=0.86, and the test was consistency. <p>CONCLUSION:Non-mydriatic fundus photography can be used as a simple and accurate method for screening diabetic retinopathy. It is simple and easy to carry out without risk. It is easy to train specialist technicians for multi-point operation. With the help of today's convenient network, the image is transmitted to an experienced ophthalmologist for reading and diagnosis, which is convenient and fast, so that the patient can be diagnosed and treated nearby, which has positive significance for the society.http://ies.ijo.cn/cn_publish/2019/1/201901031.pdfnon-mydriatic fundus photographydiabetic retinopathyscreeningapplication value |
