Outline of Final Research Achievements

The purpose of the study is to compare the efficacy and the safety of laser retinopexy between endo-laser application using 532nm laser and trans-scleral laser application using 810nm infrared laser. With endo-laser of 532nm and 0.2 sec exposure, a power of 0.15w produced appropriate burn of the retina and bleeding was caused with laser stronger than 0.2w. With trans-scleral laser application of 810nm and 1.0 sec exposure, a power of 0.5w produced appropriate burn of the retina and rupture of the retina was caused with laser of 1.0w. Compared with conventional endo-laser of 532nm, trans-scleral laser application needed stronger power to get appropriate laser burn. The safety energy range of the 810nm trans-scleral laser application was narrower than that of the conventional 532nm endo-laser, which might prevents common used or spread of the trans-sclera laser application.
