Title Retinal damage thresholds for multiple pulse lasers.
Bibliographic information Mar. 1973, Vol.44, No.3, p.317-318. 10 ref.
Abstract A Q-switched neodymium laser, capable of being repetitively pulsed, was used to determine the retinal damage threshold on 100 rhesus monkey eyes. Irradiations were made with repetitive pulse frequencies, as well as with single pulses. The data obtained show no significant difference between the single pulse ED-50 (median effective dose) and the ED-50 for the maximum energy pulse in any of the train pulses . Thus, a cumulative effect could not be demonstrated under the conditions of this experiment. This study is of a preliminary nature, as the number of experimental variables was limited and only one wavelength (1060 nm) was investigated.
