Fifty eyes of patients with proliferative diabetic retinopathy were followed at frequent intervals to determine the rapidity and stability of retinopathy risk factor regression after argon laser panretinal photocoagulation. Retinopathy risk factors regress rapidly after laser photocoagulation. The incidence of eyes at high risk for severe visual loss (eyes with 3 or more retinopathy risk factors) decreased from 100% prior to treatment to 28% three weeks after treatment. The early response to treatment was a good prognostic indicator of longer term results. Seventy-two percent of eyes which improved from a high- to a low-risk category by three weeks continued to remain at low risk at six months. Sixty-four percent of eyes which failed to improve to a low-risk category by three weeks continued to remain at high risk at six months. The early response to laser panretinal ablation may be used to predict longer-term results.
对50例增殖性糖尿病视网膜病变患者的眼睛进行了定期随访，以确定氩激光全视网膜光凝术后视网膜病变危险因素消退的速度和稳定性。激光光凝术后视网膜病变危险因素迅速消退。严重视力丧失高危眼（有3个或更多视网膜病变危险因素的眼睛）的发生率从治疗前的100%降至治疗后3周的28%。治疗的早期反应是长期结果的良好预后指标。在3周时从高危类别改善为低危类别的眼睛中，72%在6个月时仍保持低危状态。在3周时未能改善为低危类别的眼睛中，64%在6个月时仍处于高危状态。氩激光全视网膜光凝的早期反应可用于预测长期结果。
