目的:评价荧光素眼底血管造影(FFA)在糖尿病性视网膜病变(DR)诊断分期和指导治疗方面的价值。方法:采用FFA对135例(249只眼)糖尿病患者进行筛查,对DR临床分期进行修正,并根据FFA的分期指导治疗。结果:12只眼眼底检查未发现有DR的患者FFA显示有I期微血管瘤病变;11只眼Ⅲ期患者FFA显示毛细血管无灌注区范围比检眼镜下检出棉絮斑范围广,l3只眼出现新生血管改变;20只眼Ⅳ期患者检出比检眼镜下更多的新生毛细血管及黄斑水肿改变。结论:FFA是作为DR分期的最佳标准,且为指导激光治疗和评定光凝疗效的指标。
Objective: To evaluate the value of fluorescein angiography (FFA) in the diagnosis of diabetic retinopathy (DR) and its treatment. Methods: FFA was used to screen 135 patients (249 eyes) with diabetes mellitus. The clinical staging of DR was corrected and guided by FFA staging. Results: FFA showed no stage I microangiocarcinoma in 12 eyes with fundus examination without DR; FFA showed no range of capillary perfusion in 11 eyes with stage Ⅲ, There were neovascular changes; 20 eyes of stage IV patients detected more nasal capillaries and macular edema changes than the ophthalmoscope. Conclusion: FFA is the best standard for staging of DR and is an index to guide the laser treatment and evaluate the efficacy of photocoagulation.
