Retinal Injury From Simultaneous Exposure to 532 nm and 860 nm Laser Irradiation

Abstract

To properly assess the retinal hazards from several lasers using multiple wavelengths, the retinal effects of 10-second laser irradiation from 532 and 860 nm were determined in non-human primates for several different power combinations of these wavelengths. A total of 12 eyes were exposed using four different ratios of power levels to determine the contribution to the damage levels from each wavelength. The data are compared to the calculations resulting from use of the currently accepted method of predicting hazards from simultaneous lasing. The ANSI-Z136 - 2000 standard was used to calculate the combined maximum permissible exposure (MPE) and for comparison with the measured visible lesion thresholds, i.e., ED(50)s.
