增殖性糖尿病性视网膜病变氩激光治疗效果的影响因素

Factors influencing the therapeutic efficacy of Argon laser photocoagulation on proliferative diabetic retinopathy

采用氩激光全视网膜光凝的方法,治疗增殖性糖尿病性视网膜病变108例,108只眼。光凝后3个月,运用多元逐步判别分析的方法,对疗效与全身和眼部因素的相关关系进行了分析。结果表明,影响疗效的因素包括:视网膜新生血管的严重程度,新生血管的部位和施行全视网膜光凝的激光量。具有视乳头新生血管,或视网膜有多处新生血管,以及激光量小者,疗效较差。

108 eyes of proliferative diabetic retinopathy were treated with Argon laser panretinal photocoagulation. Three months after treatment, The systemic and local factors influencing the therapeutic effecacy were treated by 'stepwise discriminations analysis' to tind that the relevant factors included the severity and location of neovascularization and the total doses of laser irradiation. For eyes with papillar or mutiple and low dosage of laser irradiation, the therapeutic efficacy was poor.
