目的通过眼底荧光血管造影探讨糖尿病视网膜病变(DR)的眼底改变及分期,为临床激光治疗眼底病变提供依据。方法对385例糖尿病视网膜病变患者770只眼进行FFA检查,分析DR的分期,并进行激光治疗。结果轻、中度非增殖期患者478只眼,局部激光治疗黄斑水肿及环形渗出病变。重度非增殖期及增殖期患者292只眼,需做大面积播散性光凝或全视网膜光凝。结论糖尿病视网膜病变患者早期及定期眼底荧光血管造影,对DR进行分期,并根据分期选择激光光凝,可以很好的保持患者视功能。
Objective To investigate the fundus changes and staging of diabetic retinopathy (DR) by fundus fluorescein angiography and provide the basis for clinical laser treatment of fundus lesions. Methods FFA was performed in 770 eyes of 385 diabetic retinopathy patients. The staging of DR was analyzed and laser treatment was performed. Results In 478 eyes of patients with mild or moderate non-proliferative phase, local laser treatment of macular edema and annular exudative lesions. Severe non-proliferative and proliferative patients 292 eyes, need to do a large area of disseminated photocoagulation or panretinal photocoagulation. Conclusion Early and regular fundus fluorescein angiography in patients with diabetic retinopathy, staging DR and selecting laser photocoagulation according to staging can well maintain the visual function of patients.
