氩激光治疗视盘新生血管型糖尿病视网膜病变的疗效观察

目的探讨氩激光治疗视盘新生血管型糖尿病视网膜病变的疗效。方法使用氩激光对49例65眼视盘新生血管型糖尿病视网膜病变患者行超全视网膜光凝。激光治疗后3、6、12个月行荧光眼底血管造影,新生血管未消退者追加光凝。随访3~24个月(平均10.6个月)。结果超全视网膜光凝术后视力提高12眼(18.4%),视力不变36眼(55.4%),视力下降17眼(26.2%)。49眼(75.4%)新生血管消退或部分消退,16眼(24.6%)新生血管无变化或加重。47眼(72.3%)需要补充光凝。平均激光治疗量(2406±704)点。结论视盘新生血管型糖尿病视网膜病变较常规治疗需要更大的激光量,光凝术后应定期随访观察,必要时补充光凝。

Therapeutic effect of argon laser photocoagulation on proliferative diabetic retinopathy with disc neovascularization

Objective To investigate the effect of argon laser photocoagulation on proliferative diabetic retinopathy(PDR) with disc neovascularization (NVD).Methods 65 eyes of 49 patients with NVD were treated with extra panretinal photocoagulation (PRP) by argon laser.The fundus fluorescein angiography (FFA) was performed at 3 months,6 months,12 months after the treatment.The further photocoagulation was complemented for the patients who remained new vessels.The follow-up period was 3～24 months (mean 10.6 months).Results After extra PRP,vision was improved in 12 eyes (18.4%),unchanged in 36 eyes (55.4%) and decreased in 17 eyes (26.2%).Neovascularization partly or entirely regressed in 49 eyes (75.4%),and unchanged or aggravated in 16 eyes (24.6%).Further photocoagulation was done in 47 eyes (72.3%).The average number of laser was (2406±704) points.Conclusion The treatment for PDR with NVD should use much larger amount of laser than that of routine therapy.Regular follow-ups must be done and further photocoagulation can be given if necessary.
