ENDOPHOTOCOAGULATION THROUGH PERFLUORODECALIN IN RABBIT EYES

Retinal laser endophotocoagulation through perfluorodecalin was studie d in six eyes of three Dutch-belted rabbits after vitrectomy. Both the energy density threshold (EDT/50) and the energy threshold necessary to obtain a therapeutic lesion were evaluated. Both argon and semicond uctor diode laser endophotocoagulators were used. The amount of laser power energy and the histology of chorioretinal lesions were similar w hen photocoagulating through perfluorodecalin, compared to photocoagul ation through balanced salt citrate-buffered solution. This experiment al study indicates that no extra care is necessary when retinal endoph otocoagulation is performed through perfluorodecalin, as long as circu lar spots are obtained and energy is delivered symmetrically to the ta rget site.
