背景：PASCAL是一种半自动光凝器，它以快速预定的顺序提供多个烧伤的模式阵列，并只需一次脚踏板下沉。为了实现这一点，每次燃烧被减少到10或20毫秒。方法：将60例患者分为A组、B组、C组、D组，每组60例，A组行全视网膜光凝(PRP)，B组行黄斑或改良栅格激光治疗，C组行黄斑网格加D组视网膜固定术。结果：A组31/34例，B组24/26例，C组5/7例，D组8例均获得成功。与传统激光相比，PASCAL需要的功率明显更高(p
Background: The Pascal is a semiautomated photocoagulator that delivers a pattern array of multiple burns in a rapid predetermined sequence with a single foot pedal depression. Each burn is reduced to 10 or 20 ms to achieve this. The authors report their early experience with this system.Methods: 75 procedures done in 60 patients divided into four groups-group A, patients undergoing panretinal photocoagulation (PRP); group B, patients undergoing focal or modified grid macular laser; group C, patients undergoing macular grid and group D, patients undergoing retinopexy-were retrospectively studied.Results: 31/34 procedures in group A, 24/26 procedures in group B, 5/7 procedures in group C and all eight patients in group D had successful outcomes. Significantly higher powers were required with the Pascal than with conventional laser (p
