A Preliminary Comparison of the Transient Effects of Single versus Multiple Q-Switched Doubled-Neodymium Laser Pulses.
Abstract
A comparison between the effects of single and multiple laser pulse-trains of equivalent energy was performed. Visual evoked potentials (VEPS) recorded bipolarly from the visual cortex of two rhesus monkeys in response to a counterphasing grating were used to assess the magnitude of the visual loss following four types of exposures: single and multiple pulses with total energies equal to 50% and 500% of the maximum permissible exposure (MPE) standard for humans. The results showed that the effects of a series of laser flashes presented within 200ms are similar to those of a single laser flash whose energy is equivalent to the cumulative energy of the multiple-pulse exposure. Keywords include: Flashblindness; Laser radiobiology; Multiple pulse; Q-switched; Radiation effects; Rhesus monkey; Visual evoked potential.
