Laser panretinal photocoagulation has proven its efficacy in controlling proliferative diabetic retinopathy. It is unclear exactly how photocoagulation works: several mechanisms are evoked, involving the pigment epithelium, the photoreceptors and the retinal microvascularization. Indications for treatment and the way of carrying it out are reviewed. Possible complications related with photocoagulation can occur. Some advanced or complicated forms of proliferative diabetic retinopathy need alternative treatments like cryotherapy or vitreoretinal surgery.
激光全视网膜光凝已证明其在控制增殖性糖尿病视网膜病变方面的疗效。光凝的确切作用机制尚不清楚：人们提出了几种机制，涉及色素上皮、光感受器和视网膜微血管形成。本文综述了治疗指征及实施方法。光凝可能会出现相关并发症。一些晚期或复杂形式的增殖性糖尿病视网膜病变需要诸如冷冻疗法或玻璃体视网膜手术等替代治疗。
