| Abstract;Transscleral retinal photocoagulation possesses advantages over cryoretinopexy and diathermy, but the technique is yet to be clinically applied. In this study, argon and diode lasers were used to perform transscleral retinal photocoagulation on the eyes of colored domestic rabbits. The effectiveness of transscleral retinal photocoagulation and problems regarding its clinical application were evaluated histologically considering the differences of wavelength. Transscleral retinal photocoagulation was performed using an argon laser on one eye and a diode laser on the other of 6 colored domestic rabbits. The eyeballs were excised after either 2 or 16 days and evaluated histopathologically. The diode laser resulted in less variation in the inner retinal layers 2 days after coagulation, but 16 days after coagulation, the extent of chorioretinal adhesion was similar. In addition, postoperative degeneration and fibrosis in the inner scleral layer was observed, but the changes were minimal. In transscleral retinal photocoagulation, both the argon and diode lasers had sufficient coagulation effect. With further refinement, the technique should be ready for clinical application.
