In this study, argon green (514 nm), krypton red (647 nm), and diode (810 nm) lasers were used to produce transpupillary photocoagulations on rabbit chorioretina to simulate a retinal buckle treatment. To evaluate the efficacy of the diode laser in creating a retinopexy effect, the morphologic aspects of the acute lesions and scar development were compared. The study of the acute lesions revealed that the chorioretinal thermal damage produced by the argon green laser involved all the retinal layers and the retinal pigment epithelium. The use of the krypton red and the diode lasers resulted in deeper chorioretinal thermal damage. Two months after the treatments, all the lesions resulted in adhesive chorioretinal pigmented scars. However, the diode lesions produced a deeper scar, characterized by marked chorioretinal atrophy.
在本研究中,使用氩绿(514纳米)、氪红(647纳米)和二极管(810纳米)激光对兔脉络膜视网膜进行经瞳孔光凝,以模拟视网膜外加压治疗。为评估二极管激光产生视网膜固定效果的疗效,对急性病变的形态学特征和瘢痕形成进行了比较。急性病变研究显示,氩绿激光造成的脉络膜视网膜热损伤累及所有视网膜层和视网膜色素上皮。氪红激光和二极管激光的使用导致了更深的脉络膜视网膜热损伤。治疗两个月后,所有病变均形成了粘连性脉络膜视网膜色素性瘢痕。然而,二极管激光造成的病变产生了更深的瘢痕,其特征为明显的脉络膜视网膜萎缩。
