Radiant Energy and the Eye

Abstract: Ophthalmology Series. (Pp 321, Figs 167, Tables 41. £25.00). London: Bailliere Tindall, 1980. THIS well presented and well organised book discusses the known and potential effects and hazards of radiant energy on the eye. It admirably correlates current scientific knowledge concerning radiant erergy with its biological effects on ocular structures and documents the various mechanisms whereby v;\; -)us electromagnetic wavelengths precipitate physiological and pathological alterations within certain ocular tissues. The basic principles of radiant energy, including the absorption of radiant energy and classical and quantum mechanisms are succinctly and clearly outlined in an introductory chapter. Subsequent chapters examine the susceptibility of various ocular tissues to radiant energy and include detailed anatomical, physiological and biochemical descriptions of the cornea, lens, vitreous and retina. The information is up-to-date, well referenced and complemented by suitable tables, figures, and some outstanding illustrations. Specific sections are allocated to the biological and chemical effects of ultraviolet, infrared, microwave, radio frequency, electrical and ionizing radiations on the eye, and where applicable, safety standards are documented and discussed. There is a section on the effects of visible radiation (including lasers) on the eye, which will have particular relevance to all ophthalmologists, particularly those undertaking indirect ophthalmoscopy and photocoagulation. This book will have particular appeal to ophthalmologists and basic scientists engaged in eye research, and will also provide interesting and profitable reading for general physicians, radiotherapists and radiobiologists.

Effects of carbon dioxide laser radiation on bone: an initial report.

Abstract: : A study of the effects of carbon dioxide laser radiation on bone was conducted. Results indicated that wounds produced by a carbon dioxide laser have a retarded rate of healing when comparable size produced by a surgical bur. The retarded healing is probably due to the presence of a black, carbonaceous surface material resulting from the thermal effects of laser radiation. (Author)

Obstetrics, Essentials of Clinical Practice
