糖尿病视网膜病变46例激光光凝治疗疗效观察

目的探讨激光光凝治疗糖尿病性视网膜病变的治疗效果。方法对我院近4年来46例81眼的糖尿病性视网膜病变行激光光凝治疗后,定期观察视力,眼底及眼底荧光造影检查(3～4月后),记录新生血管、视网膜出血渗出、玻璃体积血等变化情况,观察期4月至2年。结果视网膜光凝治疗后视力变化1月后视力提高>2行,48眼,无变化的有26眼,视力下降>2行,20眼。眼底情况经FFA观察及检眼镜检查,在有效的光凝点数下,81眼中52眼1～2月微血管瘤基本消退,6眼经再次补充光凝后渐消退,8眼无变化,2眼进展为增生期糖尿病性视网膜病变;反复出现小的出血,均经再次补充光凝后于4～8月渐吸收。结论激光光凝是治疗糖尿病性视网膜病变的有效方法。

Effect observation of laser photocoagulation curative for 46 patients with diabetic retinopathy

Objective To evaluate the effect of laser photocoagulation for diabetic retinopathy treatment.Methods 81 eyes of 46 diabetic retinopathy cases were treated with the line of laser photocoagulation in recent 4 years at our hospital.Regular visual acuity,fundus examination,fundus fluorescein angiography(3-4 months after treatment)were done.Neovascularization,retinal hemorrhage,bleeding out,vitreous hemorrhage,etc.were recorded.All cases were observed for 4 months to 3 years.Results The changes of visual acuity after retinal photocoagulation treatment in 1 month increased much more than 2 lines in 48 eyes,had no change in 26 eyes,decreased more than 2 lines in 20.Microaneurysms were almost regressed in 52 of 81 eyes under the effective photocoagulation points with fundus observation by the FFA and ophthalmoscopy after 1 to 2 months,gradually subsided in 6 eyes after re-added photocoagulation.There were no changes in 8 eyes.And those were developed as proliferative diabetic retinopathy in 2 cases;recurring small hemorrhage were getting absorbed after supplemented laser photocoagulation in another 4 to 8 months.Conclusion Laser photocoagulation treatment for diabetic retinopathy was an effective method.
