目的:探讨倍频532nmNd∶YAG激光治疗视网膜静脉阻塞的方法及疗效。方法:回顾性分析我院近年应用倍频Nd∶YAG激光仪治疗视网膜静脉阻塞病例42例,根据其分型及眼底血管荧光造影改变,采用不同的光凝方法进行治疗,并分析其疗效。结果:42例视网膜静脉阻塞病例视力提高者(2行以上)4眼(10%);视力无明显变化者30眼(71%);视力下降者(2行以上)8眼(19%);眼底荧光血管造影(fundusfluoresceinangiography,FFA)检查显示视网膜出血吸收、黄斑水肿消退,治疗有效者38眼(90%)。结论:尽管对非缺血型和缺血型视网膜静脉阻塞的治疗目的和方法有所不同,倍频Nd∶YAG激光能有效地缩短病程,促进视网膜出血吸收和视力恢复,预防和减少并发症的发生。

AIM: To evaluate the curative effect of Nd∶YAG laser photocoagulation in the treatment of retinal vein occlusion(RVO). METHODS: Forty-two eyes of 42 patients diagnosed as RVO by fundus fluorescein angiography(FFA) were photocoagulated by frequency-doubled Nd∶YAG laser. Different methods were applied for different types, the visual acuity were compared and fundus changes were observed by FFA after photocoagulation. RESULTS: The visual acuity of 4 eyes (10%) improved after treatment;30 eyes (71%) remained the same;8 eyes’(19%) visual acuity decreased. It was effective in 38 eyes of the patients treated with Nd∶YAG laser photoco- agulation showed by FFA, the efficiency rate was 90%. CONCLUSION: Frequency-doubled Nd∶YAG laser photo- coagulation is effective in the treatment of RVO. It not only helps the absorption of retinal edema, hemorrhage and exudation, but also prevents the occurrence of proliferative vitreoretinopathy or neovascular glaucoma.
