摘　　要：目的探讨倍频固体激光治疗视网膜静脉阻塞的方法和疗效。方法应用倍频固体激光治疗视网膜静脉阻塞46例47眼，对其中10眼行全网膜光凝术，37眼行局域性视网膜光凝术，治疗次数1-4次，光凝后3m-6m随访，4眼复查后行补充光凝。对比分析治疗前后视力及眼底荧光血管造影（FFA）情况。结果激光治疗后视力提高（2行以上）者5眼（10．6％）；视力无明显变化者29眼（61．7％）；视力下降者13眼（27．7％）。荧光血管造影显示治疗有效42眼（89．4％），治疗无效5眼（10．6％）。结论激光治疗虽不能明确提高视力，但能促进水肿、出血、渗出的吸收，阻止病变的进一步发展，防止增殖陛玻璃体视网膜病变和新生血管性青光眼的发生。Objective To investigate the curative method and effect of Nd： YAG laser photocoagulation treatment of retinal vein occlusion. Methods Forty seven eyes of 46 patients with retinal vein occlusion were photocoagulated by frequency-doubled Nd： YAG laser. 10 eyes underwent pauretinal photocoagulation, 37 eyes underwent regional retinal photocoagulation. The treatment varied from 1-4 times. Four cases received supplemental photocoagulation after reexamination. The fundus changes were observed by fundus fluorescein in angiography after photocoagulation. Results The visual acuity of 5 eyes （10.6%） improved after treatment; 29 eyes （61.7%） remained the same; 13 eyes＇ （27.7%） visual acuity deteriorated. 42 eyes of the patients with Nd： YAG laser photocoagulation treatment were effective. The efficiency rate was 89.4%. Conclusion Laser therapy does not improve the visual acuity but it does help the absorption of retinal edema, hemorrhage and exudation and the regression of neovascularization, prevent the occurrence of proliferative vitreoretinopathy or neovascular glaucoma.
