Experimental studies of laser thermal retinal injury

Health Phys. 1983 May;44(5):519-31. doi: 10.1097/00004032-198305000-00006.

Abstract

In damage tests conducted on rabbit and monkey eyes, the threshold values for retinal damage resulting from different laser radiation were determined. The reproduction of the "worst-case" situation was ensured by the test apparatus. All physical parameters, such as power/energy, exposure time, and retinal spot, were carefully controlled. Probit analysis showed a very precise determination of the threshold values based on ophthalmoscopical visibility. The attempt of a simple physical interpretation of the thresholds leads to contradictions in major points, so a detailed calculation of damage functions and thermal model calculations are necessary.
