The authors' own clinical observations have shown that a pressure-lowering effect in secondary glaucomas resistant to therapy can be obtained by photocoagulation of the pars plicata of the ciliary body using an argon laser. In order to be able to estimate the damaging effect of photocoagulation and thus to be able to administer it in a sensible dose, the authors applied this technique to four patients with tumorous eyes that had to be enucleated, with a subsequent histological and electron-microscopical scrutiny. The laser energy was varied from 750 to 2000 mW at a constant exposure time of 0.2 s and a dot size of 100 micrograms. With clear-refracting media an energy of 1000 mW brought about coagulative effects without any substantial side-effects. Damage was then generally restricted to the aqueous humorproducing formation, i.e., the ciliary epithelium and the adjacent stromal part.
作者自身的临床观察表明，对于抗治疗的继发性青光眼，使用氩激光对睫状体皱襞进行光凝可获得降压效果。为了能够评估光凝的损伤作用，从而能够合理给药，作者将该技术应用于4例必须摘除眼球的肿瘤性眼病患者，随后进行了组织学和电子显微镜检查。在0.2秒的恒定曝光时间和100微克的光斑大小下，激光能量在750至2000毫瓦之间变化。在透明屈光介质的情况下，1000毫瓦的能量产生了凝固作用，且没有任何明显的副作用。损伤通常仅限于产生房水的结构，即睫状体上皮和相邻的基质部分。
