染料调Q红宝石激光视网膜损伤阈值研究

Studies on retinal damage thresholds of Q-switched ruby laser

本实验用染料调Q红宝石激光照射青紫蓝灰兔60只眼,求得视网膜凝固出血损伤阈值和单纯出血阈值分别为361μJ/cm^2和481μJ/cm^2,95％置信限分别为330μJ/cm^2～394μJ/cm^2和451μJ/cm^2～514μJ/cm^2。

The thresholds of retinal injury of rabbit eye is experimen- tally determined, by means of exposing the eye to Q-switch ruby laser light. The results show that the coaglating-bleeding threshold (ED_(50)) of retinal injury is 361μJ/cm^2, the bleeding damage threshold (ED_(50)) is 481μJ/cm^2. The 95% confidence levels are 330μJ/cm^2~394μLJ/cm^2 and 451μJ/cm^2~514μJ/cm^2, respectively.
