Abstract

Retinal laser endophotocoagulation through perfluorodecalin was studied 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 semiconductor diode laser endophotocoagulators were used. The amount of laser power energy and the histology of chorioretinal lesions were similar when photocoagulating through perfluorodecalin, compared to photocoagulation through balanced salt citrate-buffered solution. This experimental study indicates that no extra care is necessary when retinal endophotocoagulation is performed through perfluorodecalin, as long as circular spots are obtained and energy is delivered symmetrically to the target site.

摘要

在三只荷兰带兔的六只眼睛进行玻璃体切除术后，研究了通过全氟萘烷进行视网膜激光眼内光凝治疗。评估了获得治疗性病变所需的能量密度阈值（EDT/50）和能量阈值。使用了氩激光和半导体二极管激光眼内光凝器。与通过平衡盐柠檬酸盐缓冲溶液进行光凝相比，通过全氟萘烷进行光凝时，激光功率能量的量和脉络膜视网膜病变的组织学相似。这项实验研究表明，只要获得圆形光斑并将能量对称地传递到目标部位，通过全氟萘烷进行视网膜眼内光凝时无需格外小心。
