摘　　要：目的探讨糖尿病虹膜病变在荧光素虹膜血管造影(IFA)联合荧光素眼底血管造影(FFA)影像中的特征。方法采用横断面研究,纳入2013年5月至2020年5月在河南省立眼科医院接受IFA联合FFA检查的增生型糖尿病视网膜病变(PDR)合并糖尿病虹膜病变(DI)患者44例65眼,包括非增生性糖尿病虹膜病变(NPDI)组和虹膜红变组。所有患者均行视力、眼压、裂隙灯显微镜、IFA联合FFA检查。应用IFA检查观察2个组虹膜影像特征和前房内荧光素消退时间,应用FFA检查观察2个组视网膜影像特征和视盘新生血管发生率。为避免患者对侧眼IFA检查时间存在统计误差,仅对双眼患者的单眼数据进行分析。结果 IFA影像显示30例50眼为NPDI,14例15眼为虹膜红变。NPDI组前房内荧光素消退时间为(3.37±0.11)min,明显短于虹膜红变组的(6.02±0.29)min,差异有统计学意义(t=8.541,P<0.001)。NPDI组和虹膜红变组FFA检查均见视网膜新生血管性强荧光。NPDI组视盘新生血管发生率为20%(6/30),明显低于虹膜红变组的50%(7/14),差异有统计学意义(P=0.04)。结论糖尿病虹膜红变可以通过IFA动态的影像特征和前房内荧光素消退时间来确诊,PDR合并视盘新生血管需IFA联合FFA检查来评估。Objective To investigate the imaging features of iris fluorescein angiography(IFA)combined with fluorescein fundus angiography(FFA)in diabetic iridopathy.Methods A cross-sectional study was conducted.Sixty-five eyes of 44 patients with proliferative diabetic retinopathy(PDR)combined with diabetic iridopathy(DI)were enrolled in Henan Eye Hospital from May 2013 to May 2020.Patients were divided into non-proliferative diabetic iridopathy(NPDI)group and rubeosis iridis group according to the imaging results.Ophthalmic examinations including visual acuity,intraocular pressure,slit lamp miacroscopy,IFA and FFA were carried out in all patients.IFA was used to detect the iris imaging characteristics and the regression time of fluorescein in anterior chamber,and FFA was used to observe the retinal image characteristics and the incidence of optic disc neovascularization.To avoid the statistical error of recording the IFA examination time of the contralateral eye,only the relevant data of the affected eyes were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital(No.HNEECKY-2020[06]).Written informed consent was obatined from all patients before any medical examination.Results Among the patients,30 cases(50 eyes)were with NPDI and 14 cases(15 eyes)were with rubeosis iridis.The fluorescein regression time in anterior chamber of NPDI group was(3.37±0.11)minutes,which was significantly shorter than(6.02±0.29)minutes of rubeosis iridis group(t=8.541,P<0.001).Strong fluorescence of retinal neovascularization was observed in both groups.The incidence of optic disc neovascularization in NPDI group was 20%(6/30),which was significantly lower than 50%(7/14)in rubeosis iridis group(P=0.04).Conclusions Diabetic rubeosis iridis can be diagnosed by the imaging features of IFA and the fluorescein regression time in anterior chamber.PDR combined with optic disc neovascularization should be evaluated by FFA combined with IFA.
