A group of 20 patients (28 eyes) with proliferative retinopathy who required extensive argon laser photocoagulation to induce regression of new vessels is presented. The mean number of burns applied to each eye was 7225, with a maximum of 11,513. These were delivered in a mean of nine sessions over a mean period of 22.9 months. Twenty-five eyes (89%) had a final visual acuity of 6/18 or better. The remaining three eyes (11%) had severely reduced vision attributable to complications of proliferative diabetic retinopathy (traction retinal detachment involving the macula in two eyes and ischaemic maculopathy and a persistent vitreous haemorrhage in the third). Large amounts of confluent argon laser photocoagulation may be necessary for the elimination of new vessels in some patients, and it is our view that laser photocoagulation should be continued until regression of new vessels occurs. This is compatible with the retention of functional vision and good visual acuity.
本文报告了一组20例（28只眼）增生性视网膜病变患者，这些患者需要进行广泛的氩激光光凝以促使新生血管消退。每只眼接受的平均烧灼点数为7225个，最多为11513个。这些烧灼点平均分9次进行，历时平均22.9个月。25只眼（89%）最终视力达到6/18或更好。其余3只眼（11%）视力严重下降，原因是增生性糖尿病视网膜病变的并发症（两只眼黄斑区发生牵拉性视网膜脱离，第三只眼出现缺血性黄斑病变和持续性玻璃体积血）。对于某些患者，可能需要大量融合的氩激光光凝来消除新生血管，我们认为应持续进行激光光凝，直到新生血管消退。这与保留功能性视力和良好的视敏度是相符的。
