Since its discovery in the 1940s, retinal photocoagulation has evolved immensely. Although the first photocoagulators used incandescent light, it was the invention of the laser that instigated the widespread use of photocoagulation for treatment of retinal diseases. Laser permits selection of electromagnetic wavelength, energy levels, spot size and pulse duration. These variables are crucial for accurate targeting of retinal tissue and prevention of detrimental side-effects such as central blind spots. There is ongoing clinical research dedicated to optimising such parameters and many innovative modes of laser delivery are now being offered. Laser photocoagulation is the mainstay of treatment for various retinal and macular diseases. Considering the escalating prevalence of such conditions and widespread use of photocoagulation, it is important for optometrists to grasp the basic principles and be aware of new developments in retinal laser therapy.
自20世纪40年代被发现以来，视网膜光凝术有了巨大的发展。尽管最初的光凝器使用的是白炽灯，但激光的发明促使光凝术广泛用于治疗视网膜疾病。激光可选择电磁波长、能量水平、光斑大小和脉冲持续时间。这些变量对于准确靶向视网膜组织以及预防诸如中央盲点等有害副作用至关重要。目前正在进行致力于优化此类参数的临床研究，并且现在有许多创新的激光传输模式可供选择。激光光凝术是治疗各种视网膜和黄斑疾病的主要方法。鉴于此类病症的患病率不断上升以及光凝术的广泛应用，验光师掌握视网膜激光治疗的基本原理并了解其新进展非常重要。
