目的 通过眼底荧光血管造影（ＦＡ）方法发现糖尿病早期无症状的糖尿病视同病变（ＤＲ），提高其早期诊断率。方法 对无视力、视物改变糖尿病病人１２０例，进行眼底一般检查，对上述检查可疑的眼底，进行ＦＡ检查。结果１２０例病人中，眼 底一般检查发现ＤＲ１１例１４只眼，可疑３８例４６只眼；可疑眼底中经ＦＡ检查发现ＤＲ单纯期２６例２８只眼。结论ＦＡ方法 可明显提高糖尿病视膜病变的早期诊断率，是一种更加可靠的检查方法，有重要的临床应用价值。
Objective To detect asymptomatic diabetes with pathological changes (DR) by fundus fluorescein angiography (FA) and to improve its early diagnosis rate. Methods 120 cases of diabetic patients without visual acuity and visual changes were examined by general fundus examination and FA examination was performed on the above suspicious fundus examination. Results Among the 120 patients, 14 eyes of DR11 and 46 eyes of 38 suspicious cases were found in the fundus examination. In the suspicious fundus examination, only 26 cases of DR were diagnosed in 28 eyes by FA. Conclusion FA method can significantly improve the early diagnosis of diabetic retinopathy, is a more reliable method of examination, has important clinical value.
