Book Description
The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.

Book Description
Who would have thought that a basic eye alignment problem could cause a person to be miserable or disabled? Yet that is exactly what is happening with Vertical Heterophoria (VH), a visual condition where there is a slight vertical image misalignment which causes headaches, dizziness, anxiety, neck pain and reading difficulties. Using techniques developed by Dr. Debby Feinberg, patients are fit with prism eyeglass lenses that realign the images, resulting (on average) in an 80% reduction of symptoms. This book contains the stories of those suffering from VH, their difficult journey through life and the medical system, and their recovery and return to health using just a simple pair of properly prescribed prism lenses."Who, indeed, could have supposed that a mere ocular defect could have given rise to so serious a train of evils...and who that had not seen it, could believe that the correction by glasses of the eye trouble could have given a relief so speedy and so perfect that the patient described it as a miracle?" Dr. S. Weir Mitchell, Neurologist and Headache Specialist Philadelphia, PA Headaches and Eye Strain, April 1876

Book Description
This book covers all aspects of the visual system from sensory aspects to eye movements, attention, and visual memory in a brief format. Each chapter describes the psychology, followed by where in the brain that aspect is dealt with, the properties of the cells in that area, and what happens if a patient has a lesion or stroke in that area.

Book Description
The long-awaited second edition of an authoritative reference on electrophysiologic vision testing, including detailed information on techniques and problems, basic physiology and anatomy, theoretical concepts, and clinical findings; with extensive new material. This authoritative text is the only comprehensive reference available on electrophysiologic vision testing, offering both practical information on techniques and problems as well as basic physiology and anatomy, theoretical concepts, and clinical correlations. The second edition, of the widely used text, offers extensive new material and updated information: 65 of the 84 chapters are completely new, with the changes reflecting recent advances in the field. The book will continue to be an essential resource for practitioners and scholars from a range of disciplines within vision science. The contributions not only cover new information—important material that is likely to become more important in the next decade—but also offer a long-range perspective on the field and its remarkable development in the last century. After discussing the history and background of clinical electrophysiology, the book introduces the anatomy of the retina and principles of cell biology in the visual pathways at the molecular, physiological, and biochemical levels. It relates these new findings to the techniques and interpretations of clinical tests, including the electro-oculogram (EOG), electroretinogram (ERG), and visual evoked potentials (VEP), which are discussed in detail, as are equipment, data acquisition and analysis, principles and protocols for clinical testing, diseases and dysfunction, and animal testing. Notable additions for this edition include chapters on the origin of electroretinogram waveforms, multifocal techniques, testing in standard laboratory animals, recent advances in analysis of abnormalities in disease, and the applications of these techniques to the study of genetic abnormalities.
