目的 探讨激光治疗增殖型糖尿病性视网膜病变（ＰＤＲ）的疗效。方法 随机应用倍频Ｎｄ：ＹＡＧ激光和砷化镓半导体激光对ＰＤＲ患者行全视网膜光凝术（ＰＲＰ），视网膜任何部位新生血管（ＮＶＥ）给予密集直接光凝，视盘新生血管（ＮＶＤ）不予直接照射。结果 ＰＤＲ患者于ＰＲＰ术后３月６１．５％患眼新生血管消退，１２月７６．２％新生血管消退，ＮＶＤ和ＮＶＥ眼中分别为５８．８％和８８．０％，术后２年以上９４．１％新生血管消退；对ＰＲＰ有成功反应者平均视力有提高。结论 ＰＲＰ对ＰＤＲ有显著疗效，能有效改善和保持患者视力，对ＰＲＰ有成功反应者视力预后较好，ＮＶＥ较ＮＶＤ更容易消退。
Objective To investigate the effect of laser treatment of proliferative diabetic retinopathy (PDR). Methods Total retinal photocoagulation (PRP) was performed in patients with PDR by double frequency Nd: YAG laser and GaAs semiconductor laser irradiation. NVD was intensively and directly photocoagulated in all patients with retinal degeneration. The optic disc neovascularization (NVD) Direct exposure. Results In 61.3% of patients with PDR, retinal neovascularization subsided in 61.5% of PRP patients, 76.2% of neovascularization was regressed in December, and 58.8% and 88.0% in NVD and NVE eyes respectively. After 2 years or more 94.1% neovascularization subsided; the average responders with successful PRP had improved vision. Conclusion PRP has a significant effect on PDR, which can effectively improve and maintain the visual acuity of patients. PRP has a good prognosis of visual acuity, NVE is more likely to subside than NVD.
