Ocular Effects of Near Infrared Laser Radiation for Safety Criteria

Abstract

Ocular effects of near infrared laser radiation were studied using a Nd3+ - YAG laser which emitted light at a wavelength of 1060 nm in the TEM00 mode. Retinal burn data were obtained on rhesus monkey eyes with the exposure duration used as a parameter. The exposures were for 1 sec, .1 sec, .01 sec, . 001 sec and .0000001 sec durations and for trains of the .0000001 sec pulses with a pulse repetition rate of lkHz lasting for 0.5 sec. Thirty eyes were irradiated for each exposure duration. The data were analyzed to find the energy per pulse corresponding to the retinal burn probability P=0.5 using (1) a probit analysis and (2) a straightforward arithmetical averaging of the retinal burn thresholds obtained for each eye.
