目的:探讨YAG激光治疗糖尿病视网膜病变(diabeticretinopathy,DR)的临床疗效。方法:应用YAG532nm激光,对142例247眼DR患者进行视网膜激光光凝治疗。结果:激光治疗后,有198眼视力提高,新生血管完全或部分消退,有效率达80.2%。其中增生前期糖尿病视网膜病变(PPDR)及早期增生期糖尿病视网膜病变(PDR)患者有效率92.0%。显著高于高危PDR患者有效率41.7%。结论:YAG532nm激光治疗DR有效,并且PPDR及早期PDR治疗效果更佳。

AIM:To evaluate the therapeutic effect of YAG laser for diabetic retinopathy(DR).METHODS:A total of 142 cases 247 eyes with DR were treated with photocoagulation by YAG 532nm laser.RESULTS:Visual acuity was improved in 198 eyes after the treatment of panretinal photocoagulation,and neovascularization disappeared completely or partially,favorable response rate was 80.2%.The effective rate of preproliferative diabetic retinopathy(PPDR)and early proliferative diabetic retinopathy(PDR)was totally 92.0%,showing significantly higher favorable response rate than that of the eyes with high-risk PDR(41.7%).CONCLUSION:YAG 532nm laser is effective for DR,and better clinical outcome can be expected from early intervention.
