摘要

激光诱导视网膜热损伤的阈值随激光照射的持续时间而变化,激光安全指南中给出的MPEs预计将定义在整个照射持续时间范围内不会导致视网膜损伤的照射水平。激光视网膜暴露MPE的时间依赖形式是在1972年根据实验确定的阈值数据建立的。自1972年以来积累了更多的阈值数据。本文将当前可用的时间依赖阈值数据与最新版本的激光安全指南中定义的MPE进行了比较。激光诱导的视网膜热损伤阈值随激光暴露的持续时间而变化,激光安全指南中给出的MPEs预计将定义在整个暴露持续时间范围内不会导致视网膜损伤的暴露水平。激光视网膜暴露MPE的时间依赖形式是在1972年根据实验确定的阈值数据建立的。自1972年以来积累了更多的阈值数据。本文将当前可用的时间相关阈值数据与最新版本的激光安全指南中定义的MPE进行了比较

Time dependence of laser-induced retinal thermal injury
The threshold for laser-induced thermal retinal injury varies with the duration of the laser exposure and the MPEs as given in the laser safety guidelines are expected to define exposure levels not anticipated to result in retinal injury across the entire range of exposure durations. The form of the time dependence of the MPE for laser retinal exposures was established in 1972 based on the experimentally determined threshold data available at that time. More threshold data has accumulated since 1972. This paper compares the currently available time dependent threshold data to the MPE as defined in the most recent version of the laser safety guidelinesThe threshold for laser-induced thermal retinal injury varies with the duration of the laser exposure and the MPEs as given in the laser safety guidelines are expected to define exposure levels not anticipated to result in retinal injury across the entire range of exposure durations. The form of the time dependence of the MPE for laser retinal exposures was established in 1972 based on the experimentally determined threshold data available at that time. More threshold data has accumulated since 1972. This paper compares the currently available time dependent threshold data to the MPE as defined in the most recent version of the laser safety guidelines
