Book Description
The overall purpose of this research was to investigate a method for demonstrating changes in retinal ganglion-cell function after high-intensity radiation such as from a laser or other monochromatic source in the visible region. These experiments were designed to facilitate understanding functional retinal changes required to produce flash-blindness or permanent damage in human eyes, especially in the macular region which is so important in safety measures. Recordings were made from selected and well-characterized ganglion cells in animal retinas. Changes in receptive-field sensitivities were detected as a result of exposure to high-intensity monochromatic or broad-band light in part or all of the field. The time course of sensitivity recovery was also plotted. These results were then correlated with physiological and psychophysical data already known from other animal and human studies. The specific objective of this study was to delineate means by which ganglion cell responses could be used to evaluate color vision and visual-field loss after laser exposure of the monkey retina. Rabbit and cat retinas were used in developing the experimental techniques required for this evaluation. (Author).

Book Description
Nearly a decade aga a general review article on the evaluation of optical radia tion hazards was published in Applied Optics (Sliney and Freasier, 1973). This arti cle received many favorable comments but also prompted many inquiries regarding specific optical hazard problems. From this it became evident that a monograph rather than a supplemental and expanded article was needed to fill this literature gap relating to laser and optical radiation hazards. The present work is designed to fill that gap, and is structured to permit either classroom or self-study use. Much of the material in this book was developed in eonnection with short courses on laser safety and radiometry in which we have participated, as weIl as from our previous articles. In particular, the sequenee of chapters is based upon the experiences which we have had in lecturing in courses with different schedules. One of the great difficulties in developing a text of this nature is that a broad, multidisciplinary background must be included in order that the reader can comprehend all of the subjeet matter readily. For this reason, the material presented on anatomy and physiology is orien ted toward the engineer or physical scientist, while the review material on basic optical physics is intended more for the physician or life scientist.
