This book represents a logical summary of the author's extensive experience and personal convictions in the field of photocoagulation, particularly with laser delivery systems. There can be little question that the selection of photographs required a great deal of effort. The illustrations are concise and easily understood. The outline and general format are well organized. For those ophthalmologists with access to an argon laser device, the highly technical emphasis on spot sizes, power settings, and durations of exposures may be of considerable advantage. There is also an important section on complications associated with photocoagulation.
The history of photocoagulation and the technology of laser development are somewhat sketchy but at least adequate. Considerable space is dedicated to tissue responses to variable laser wavelengths. There are, however, no histopathological sections to confirm the illustrations or text. Absorption of argon laser light by the middle and inner layers of the retina seems to
