Glaucoma surgery is difficult and fraught with complications. Some complications are common and mild, while others are rare and/or vision threatening. However, good outcomes are still likely if those complications encountered are managed properly. This book is intended for those surgeons wishing to improve their skills and abilities to manage difficult problems that will come up during the care of glaucoma patients. Comprising seven comprehensive sections, chapters in this volume address outflow mechanisms after glaucoma surgery, wound healing processes and modulators, complications in filtering surgery, tube shunt implantation, and angle procedures, among other topics. The authors of each chapter provide surgical and clinical pearls not only for managing difficulties but in preventing them as well. Additionally, because each surgeon has their own way of addressing a particular situation, there is commentary at the end of each chapter to provide another opinion or strategy for dealing with a particular surgical scenario. Cross-referencing is provided throughout this book to direct the reader to as many helpful sections as possible. Both thorough and highly-illustrative, this book will help both new and experienced glaucoma surgeons deal with complications and provide successful results for their patients.

Written by a leader in the field of low vision research, this book discusses the role of vision in reading, focusing on the reading performance of people with normal, healthy vision and people with impaired vision. The author describes the influence of physical properties of text on reading performance and the implications for information processing in the visual pathways. Providing an overview of seminal research, this book explores: different forms of low vision that affect reading, text characteristics that optimize reading for those with low vision, and principles underlying the legibility of text and guidelines for displaying text. Special topics include the role of the magnocellular pathway in reading and dyslexia, Braille reading, and fonts for highway signs. An accompanying CD contains reprints of the seminal series of articles by Gordon E. Legge and colleagues on the psychophysics of reading in normal and low vision, published between 1985 and 2001. This volume will be of interest to researchers and professionals in the area of low vision, including graphics engineers, HCI scientists, human factors specialists, low-vision rehabilitation specialists, opthamologists, occupational therapists, special education teachers, as well as cognitive scientists and perceptual psychologists. It is also suitable for advanced students with a background in the topic.

During the past two decades, our understanding of the molecular genetics of inherited eye diseases, their classification, and management has undergone a huge expansion as the field of human genetics has benefited from technological advances and increased interest by physicians and scientists in all fields. As a result, the amount of clinical and basic-science information on inherited systemic and eye diseases has become so large that general ophthalmologists, ophthalmic subspecialists, and physicians in other fields have found it difficult to keep up. This volume will act as a guide because it catalogues all the latest information about genetic diseases that involve the eye and presents it in a practical and accessible format. After an introductory chapter that reviews basic clinical and molecular-genetic principles, individual diseases and groups of diseases are listed alphabetically in order to make it as easy as possible to search for an entry. The material in each entry is a synthesis of numerous articles and reviews on the topic, accompanied by at least one high-quality illustration, at least one webpage of a patient support group or other organization related to the disease, and references that provide the original description of the disease, an excellent review, or useful illustrations. There is also a companion website containing electronic copies of all the illustrations to make it easy to use them in lectures. Health-care professionals who need immediate access to clinical and basic-science information on inherited systemic and eye diseases will find this volume indispensable.

In this clear and engagingly written book, Martha Farah presents the first comprehensive overview of the cognitive neuroscience of vision.

Beginning with the transformation of light images into neural images within the eye, Farah traces the processing of the visual signal throughout the brain, culminating in our conscious awareness of the objects and people we see. The perception of colour, motion, faces, printed words, and other important components of our visual world are explained, along with the related cognitive processes of visual attention and visual mental imagery.

Each chapter brings together a fascinating array of clinical anecdotes and observations, data from physiological experiments, and the latest neuroimaging studies of the normal brain at work. The unprecedented integration of the different stages of visual perception and the different approaches to these stages will be of value to students and specialists alike.

Spatial vision is a subject in which philosophy, psychology, ophthalmology, neurophysiology and pathology meet. It is the unique contribution of this book that gives a survey of the whole subject, in historical perspective. The author, a former professor of ophthalmology at the University of Amsterdam, is an authority in the field of binocular vision (Diplopia, 1973) and colour vision (History of Color, 1999). Seeing Space is written for ophthalmologists, optometrists, orthoptists and other practitioners of visual science, but also for psychologists and anybody interested in the philosophy and science of perception. The book contains three parts: Part I contains chapters on objective and subjective space and on non-visual space perception. Part II begins with a short survey of the visual system. As eye movements are of crucial importance in the perception of space, the evolution of the eye and the eye movements is described. There are chapters on the perception of direction, stereoscopic depth and movement. A sensorimotor theory of space perception is elaborated. Part III is dedicated to the perception of objects. There are chapters on the perception of contours, surfaces, dimensionality and size (including the "moon illusion"). Finally the problem of the relation between mind and matter is raised, but not solved.
