Although photocoagulation is no cure for diabetic retinopathy, it slows down or, in favourable cases, prevents further progression. In order to achieve the desired therapeutic effect, photocoagulation has to include the ischaemic mid-periphery of the retina. Following a latency period of varying duration during which no further progression is evident either on ophthalmoscopic examination or fluorescein angiography, recurrence of neovascularization is observed in some cases. The therapeutic management entails additional panretinal photocoagulation, in particular at the periphery. The authors report on 75 patients who, following panretinal photocoagulation, were treated by additional argon-laser coagulation.
虽然光凝疗法无法治愈糖尿病性视网膜病变，但它能减缓病情发展，在有利情况下还可防止病情进一步恶化。为达到理想的治疗效果，光凝疗法必须覆盖视网膜缺血的中周部。在一段时长各异的潜伏期内，无论是眼底镜检查还是荧光素血管造影都未发现病情有进一步发展，然而在某些病例中，会观察到新生血管形成复发。治疗措施需要进行额外的全视网膜光凝，尤其是在周边部位。作者报告了75例患者，这些患者在接受全视网膜光凝后，又接受了额外的氩激光光凝治疗。
