Available in PDF, EPUB and Kindle. Book excerpt: When the eyeball is indented in total darkness, within less than 200 mil liseconds an oval or quarter-moon shaped spot of light is perceived in the part of the visual field corresponding to the indented region of the retina. In the seconds following, this phosphene extends across the whole visual field and alters in structure during further eyeball indentation. It is then seen as irregular large bright spots of light, finely structured moving light grains ('light nebula') and stationary bright stars. Regular geometrical patterns appear only when both eyes are indented simultaneously [1]. When the eyeball deformation is released, part of the retina again lights up for another one or two seconds and curved light lines are seen following the course of the larger retinal vessels (Fig. 1). In the following we will review the history of this phenomenon, which played an important role during the first 2200 years of vision theories and in the development of models to explain normal vision. 2. Pre-Socratic philosophers, Plato and Aristotle Alcmaeon of Croton (6-5th century B. C. ), who was a member of the Pythagoraean sect and one of the founders of Greek medicine, was the first to describe mechanical deformation of the eyeball leading to light sensa tions. According to Aristotle's pupil Theophrast of Eresos, Alcmaeon report ed that 'the eye obviously has fire within,for when the eye is struckfireflashes out' [2, p. 88].

Download or read book Optical Coherence Tomography in Age Related Macular Degeneration written by Gabriel Coscas and published by Springer Science & Business Media. This book was released on 2009-07-25 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid or even dramatic progress has been made in the field of AMD over recent years, leading to a constant revision of basic concepts. A wide range of fundus imaging modalities are now available, and this book explains the respective value of each technique. The information provided by OCT is presented logically by comparison with plain films, autofluorescence, fluorescein angiography, or indocyanine green angiography. Meticulous biomicroscopic examination of macular changes and the essential value of fluorescein angiography for the detection of anatomical alterations of the macula and for precise evaluation of lesions and their course by indocyanine green angiography have naturally led the author Gabriel Coscas to analyze the new data provided by OCT.

Download or read book Neuro Ophthalmology written by Andrew G. Lee and published by Springer. This book was released on 2019-01-01 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an overview on the most recent advances in global neuro-opthalmic care. Global variation in the incidence and prevalence of specific neuro-ophthalmic conditions results in geographic differences in differential diagnosis, evaluation, management, and treatment of specific disorders. It covers a variety of disorders from optic neuritis, idiopathic intracranial hypertension to traumatic optic neuropathy. To understand the key differences in neuro-ophthalmic health care, this book has gathered recognized experts from around the world to describe and define these regional and geographic variations of care. By highlighting various international approaches to diagnosing and treating neuro-ophthalmic disorders, this book will be an essential guide for neuro-ophthalmologists, ophthalmologists, and neurologists seeking to build upon their clinical skills in a global context.

Download or read book The Vitamin A Story written by R.D. Semba and published by Karger Medical and Scientific Publishers. This book was released on 2013-07-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows how vitamin A deficiency – before the vitamin was known to scientists – affected millions of people throughout history. It is a story of sailors and soldiers, penniless mothers, orphaned infants, and young children left susceptible to blindness and fatal infections. We also glimpse the fortunate ones who, with ample vitamin A-rich food, escaped this elusive stalker. Why were people going blind and dying? To unravel this puzzle, scientists around the world competed over the course of a century. Their persistent efforts led to the identification of vitamin A and its essential role in health. As a primary focus of today’s international public health efforts, vitamin A has saved hundreds of thousands of lives. But, we discover, they could save many more were it not for obstacles erected by political and ideological zealots who lack a historical perspective of the problem. Although exhaustively researched and documented, this book is written for intellectually curious lay readers as well as for specialists. Public health professionals, nutritionists, and historians of science and medicine have much to learn from this book about the cultural and scientific origins of their disciplines. Likewise, readers interested in military and cultural history will learn about the interaction of health, society, science, and politics. The author’s presentation of vitamin A deficiency is likely to become a classic case study of health disparities in the past as well as the present.

Download or read book Sociomedical Perspectives on Patient Care written by Jeffrey M. Clair and published by University Press of Kentucky. This book was released on 1993-08-10 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social change has placed new demands on the practice of medicine, altering almost every aspect of patient care relationships. Just as medicine was encouraged to embrace the biological sciences some 100 years ago, recent directives indicate the importance of the social sciences in understanding biomedical practice. Humanistic challenges call for changes in curative and technological imperatives. In this book, social scientists contribute to such challenges by using social evidence to indicate appropriate new goals for health care in a changing environment. This book was designed to stimulate and challenge all those concerned with the human interactions that constitute medical practice. To encompass a wide range of topics, the authors include researchers; practicing physicians from the specialties of family, general, geriatric, pediatric, and oncological medicine; social and behavioral scientists; and public health representatives. Cutting across disciplinary boundaries, they explore the ethical, economic, and social aspects of patient care. These essays draw on past studies of the patient-doctor relationship and generate new and important questions. They address social behavior in patient care as a way to approach theoretical issues pertinent to the social and medical sciences. The authors also use social variables to study patient care and suggest new areas of sociomedical inquiry and new approaches to medical practice, education, and research. Its cross-disciplinary approach and jargon-free writing make this book an important and accessible tool for physician, scholar, and student.
