Effect of Transscleral Diode Laser Photocoagulation Applied Through Silicone Scleral Exoplants

ABSTRACT

Authors performed transscleral diode laser retinopexy through the conjunctiva, muscle and silicone scleral exoplant to evaluate its safety and efficacy in experimental rabbit eyes. Transscleral applications required energies of average 325. 2 mWwith duration of 0.5 second. The mean power required to produce comparable lesions through the conjunctiva, muscle and the buckle(MIRA #276)was 27%, 20%, and 33%higher, respectively. These results demonstrate that the diode laser photocoagulation applied through a scleral buckle is capable to produce chorioretinal scars without damaging the scleral tissue nor the buckling elements employed.
