Abstract: The thresholds of retinal injury of rabbit eye is experimentally determined, by means of exposing the eye to Q-switch ruby laser light. The results show that the coaglating-bleeding threshold (ED50) of retinal injury is 361μJ/cm2, the bleeding damage threshold (ED50) is 481μJ/cm2. The 95% confidence levels are 330μJ/cm2~394μJ/cm2 and 451μJ/cm2~514μJ/cm2, respectively.
