Retinal Alterations Produced by Low Level Gallium Arsenide Laser Exposure.
Abstract
The retinas of rhesus monkeys were subjected to irradiation by a prototype gallium arsenide (GaAs) laser training device. The laser device operated at 1600 Hz (pulse repetition frequency mode) or 132 Hz (pulse code mode) with nominal peak pulse power of 1 watt and 10 watts. Exposure durations ranged from 1.0 sec to 90 sec. The tissue reaction at the exposure site was characterized by the development of a pale gray clouding within 10 seconds of initiation of the exposure. The nature of the retinal change could not be determined by ophthalmoscopic, histologic, or flourescein leakage techniques. (Author)
