Abstract
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.
