We treated 18 eyes with equatorial degeneration or retinal tear using carbon dioxide laser applied transs-clerally. Satisfactory chorioretinal adhesion was achieved in 17 eyes. The combination of low-power output, high stability laser system and high-transmis-sion KRS-5 fiber optics seemed to have contributed to the clinical success. As the optimum setting, we used power output level of 300 to 400 mW and 10 to 40 seconds for each laser application. Throughout the present series, we encountered no serious complications as coagulation of the sclera, chorioretinal hemorrhages or hole formation.

When compared with transscleral cryocautery, this method involved obvious merits as small lesions of variable sizes could be obtained. The fundus lesions could be identified immediately after each coagulation, enabling to perform regularly placed and precise coa-gulations. As the retinal coagulation with this system does not on the laser energy transmission through the sclera but on heat conduction radiating through the sclera, the effects to the vitreous appeared to be of negligible level.
