Abstract:

Threshold energies and probability of damage curves for retinal damage by Q-switched ruby laser operating in the TEM sub oo mode were determined in the Rhesus monkey. Threshold values were established for both a 3 mm and 8 mm diameter beam which produced estimated retinal spot sizes of 40 microns and 70 microns. The ophthalmoscopic 50 probability of damage was 16.9 and 24.7 microjoules entering the eye for 3 mm and 8 mm beams respectively for extramacular exposures and 9.8 and 12.8 microjoules respectively for macular exposures.
