Abstract:

A continuous-wave neodymium laser, operating at 1.06 micron has been incorporated into an animal exposure facility to enable the determination of the threshold for damage to ocular tissue at this wavelength for a range of exposure durations. Using Rhesus monkeys, the damage threshold has been determined for 1-second exposure duration and minimal retinal spot size. Damage was produced at exposure levels above 42 millijoules total intraocular energy TIE. The ED50 level was 56.4 millijoules TIE. Author
