Handbook of Nutrition, Diet, and the Eye, Second Edition, thoroughly addresses common features and etiological factors on how dietary and nutritional factors affect the eye. The ocular system is perhaps one of the least studied organs in diet and nutrition, yet the consequences of vision loss are devastating. There are a range of ocular defects that have either their origin in nutritional deficiencies/excess or have been shown to respond favorably to nutritional components. Featuring a new section on animal model studies where both the ocular problem and dietary remedies can be varied, there are also new chapters on dietary supplements.

Designed for students and professionals preparing for the ABO certification exam or wishing to quickly brush up on optical formulas, this easy-to-use workbook contains optical formulas, definitions, and walk-through problems with practical examples throughout. Rather than searching through dozens of optics books, readers will find all relevant information here in one source. Coverage includes everything from sine, cosine and tangent to resultant prism and resolving prism to polarized filters - and much more! Features a user-friendly format that facilitates the review process, with practical examples throughout. Provides a convenient review of optical formulas and basic math problems. Begins each chapter with a brief discussion of the topic, then proceeds with exercises and examples; answers are provided at the end of the book. New work-text design allows the reader to complete practice exercises within the book and section being studied. More complex formulas include "how to use the calculator" boxes, and multiple choice review sections have been added to the sections. Advanced exercises such as non-formula exercises are now included throughout.

While the field of vision science has grown significantly in the past three decades, there have been few comprehensive books that showed readers how to adopt a computional approach to understanding visual perception, along with the underlying mechanisms in the brain. Understanding Vision explains the computational principles and models of biological visual processing, and in particular, of primate vision. The book is written in such a way that vision scientists, unfamiliar with mathematical details, should be able to conceptually follow the theoretical principles and their relationship with physiological, anatomical, and psychological observations, without going through the more mathematical pages. For those with a physical science background, especially those from machine vision, this book serves as an analytical introduction to biological vision. It can be used as a textbook or a reference book in a vision course, or a computational neuroscience course for graduate students or advanced undergraduate students. It is also suitable for self-learning by motivated readers. in addition, for those with a focused interest in just one of the topics in the book, it is feasible to read just the chapter on this topic without having read or fully comprehended the other chapters. In particular, Chapter 2 presents a brief overview of experimental observations on biological vision; Chapter 3 is on encoding of visual inputs, Chapter 5 is on visual attentional selection driven by sensory inputs, and Chapter 6 is on visual perception or decoding. Including many examples that clearly illustrate the application of computational principles to experimental observations, Understanding Vision is valuable for students and researchers in computational neuroscience, vision science, machine and computer vision, as well as physicists interested in visual processes.

The cornea is the clear, outer layer at the front of the eyeball. It acts as a window to the eye. The cornea helps to focus light rays onto the retina, this image is then transmitted to the brain. When the cornea is damaged, it can become less transparent or its shape can change. This can prevent light reaching the retina and causes the picture transmitted to the brain to be distorted or unclear. A corneal transplant, also known as keratoplasty or a corneal graft, is an operation to remove all or part of a damaged cornea and replace it with healthy donor tissue. It is used to improve sight, relieve pain and treat severe infection or damage. One of the most common reasons for a cornea transplant is a condition called keratoconus, which causes the cornea to change shape. (NHS.UK) This book is a guide to corneal transplantation (keratoplasty) for ophthalmic surgeons. Divided into seven sections, the text begins with an overview of evolution, preoperative considerations, and eye banking. The following sections cover a multitude of keratoplasty techniques, including endothelial keratoplasty, and their potential complications. The book concludes with discussion on alternatives to corneal transplantation. The third edition of this comprehensive manual has been fully revised, with new topics added, to provide surgeons with the latest advances in the field. A selection of operative videos can be accessed via a QR code provided in the book. The previous edition (9788184488593) published in 2010.

This book covers all aspects of the visual system from sensory aspects to eye movements, attention, and visual memory. There are many books that cover the psychology and physiology of a single aspect of vision, such as color vision or eye movements. Other larger texts may offer encyclopedic coverage of the psychology of all aspects of vision. However, this is the only book on the market covering the psychology, anatomy, and physiology of all aspects of the visual system in 300 pages. Each chapter addresses a separate aspect of vision, describing the basic phenomena, where in the brain this aspect of vision occurs, the properties of the cells in those areas, and the deficits that result from a lesion or stroke in those areas. In addition to extensive illustrations, the book contains the author's selection of the literature, from the classic 19th century papers to the present. This text is designed for graduate students and advanced undergraduates in psychology, optometry, physiology, anatomy, and medicine who want to get a broad view rather than one confined to their particular discipline.
