The Handbook of Nutrition in Ophthalmology is the first general text on nutrition and eye health created for physicians, nutritionists, and researchers. The author provides important links between the epidemic of obesity and implications it has for eye disease and blindness. The volume also includes chapters addressing nutritional aspects of preventing eye disease in diabetes mellitus and other optical neuropathies, making this a unique book.
The Nutrition and Health series of books have, as an overriding mission, to provide health professionals with texts that are considered essential because each includes: 1) a synthesis of the state of the science, 2) timely, in-depth reviews by the leading researchers in their respective fields, 3) extensive, up-to-date fully annotated reference lists, 4) a detailed index, 5) relevant tables and figures, 6) identification of paradigm shifts and the consequences, 7) virtually no overlap of information between chapters, but targeted, inter-chapter referrals, 8) suggestions of areas for future research and 9) balanced, da- driven answers to patient/health professionals questions which are based upon the totality of evidence rather than the findings of any single study. The series volumes are not the outcome of a symposium. Rather, each editor has the potential to examine a chosen area with a broad perspective, both in subject matter as well as in the organization of their volume. The international perspective, especially with regard to public health initiatives, is emphasized where appropriate. The editors, whose trainings are both research and practice oriented, have the opportunity to develop a primary objective for their book; define the scope and focus, and then may invite the leading authorities from around the world to be part of their initiative. The editor/authors are encouraged to provide an overview of the field, discuss their own research and relate the research findings to potential human health consequences.
