We used a diode laser with an output power of 1 W through a fiberoptic light pipe (200 microns diameter) to deliver laser energy through the sclera of pigmented rabbits. Ciliary body destruction occurred with energy levels of 300-400 mW and exposure time of 0.5 sec. Retinal photocoagulation was achieved with energy levels of 200-500 mW in 0.5 sec. Histologic examination of acute lesions demonstrated thermal destruction of ciliary body processes and retina. Chorioretinal scar formation was observed clinically and histologically within 2-3 weeks. Our data indicate that the transscleral diode laser may be used for destruction of the ciliary body processes or peripheral retinal coagulation in pigmented eyes.
我们使用一台输出功率为1瓦的二极管激光器，通过一根直径200微米的光纤光导管，将激光能量透过有色家兔的巩膜进行传递。当能量水平为300 - 400毫瓦且曝光时间为0.5秒时，睫状体遭到破坏。在0.5秒内，当能量水平为200 - 500毫瓦时，可实现视网膜光凝。急性病变的组织学检查显示睫状体突和视网膜发生了热破坏。在2 - 3周内，临床和组织学上均观察到脉络膜视网膜瘢痕形成。我们的数据表明，经巩膜二极管激光器可用于破坏有色眼睛的睫状体突或进行周边视网膜光凝。
