Visual Compensatory Tracking Performance after Exposure to Flashblinding Pulses. II. Sub-Damage-Threshold Laser Irradiation of Rhesus Monkey Subjects

Abstract

Two rhesus monkeys were exposed to green or multicolor (white) laser pulses while performing a visual compensator tracking test. The pulses were approximately 200 nsec in duration; energy deposited on the retina ranged from 0.55 to 3.75 micro J. A total of 99 exposures were recorded. Flashblindness recovery times (FBT's) were determined by examination of postexposure tracking error plots. Most exposures had no apparent effect. Average FBT from exposures that produced events was 1.9 + or - 0.8 sec; no dose-response relationship was evident. These exposure-related events were indistinguishable in appearance from random startle events that occurred frequently during task performance. We concluded that, for these studies, the laser exposures caused momentary startles that were probably not true flashblindness incidents.
