BACKGROUND/AIMS: The pattern scan laser photocoagulator (PASCAL) is a novel laser device that uses 10-30 ms pulse duration for retina photocoagulation. The aim of this study was to analyse the safety profile of this approach.
This was a retrospective study. We reviewed the clinical records of all laser sessions performed with PASCAL from November 2007 to July 2008. Where there were any complications, we recorded the laser parameters, type, affected retina region, postoperative interval and treatment if required.
There were 1301 consecutive cases. Complications included 17 cases of retinal bleeding (1.3%), two cases of choroidal detachment (0.15%) and one case of exudative retinal detachment (0.07%). There was no statistical difference between the laser parameters used in patients with or without complications.
The laser parameters for PASCAL are safe. The complications and adverse effects encountered in this series are similar to those reported in other studies.
背景/目的：模式扫描激光光凝仪（PASCAL）是一种新型的激光设备，用于视网膜光凝的脉宽为 10-30 毫秒。本研究旨在分析该方法的安全性。
这是一项回顾性研究。我们回顾了 2007 年 11 月至 2008 年 7 月期间使用 PASCAL 进行的所有激光治疗的临床记录。如果出现任何并发症，我们记录了激光参数、类型、受影响的视网膜区域、术后间隔以及是否需要治疗。
共有 1301 例连续病例。并发症包括 17 例视网膜出血（1.3%）、2 例脉络膜脱离（0.15%）和 1 例渗出性视网膜脱离（0.07%）。有并发症和无并发症患者的激光参数之间无统计学差异。
PASCAL 的激光参数是安全的。本系列中遇到的并发症和不良反应与其他研究报道的相似。
