Making Eye Health a Population Health Imperative


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.

United States Code


Book Description

"The United States Code is the official codification of the general and permanent laws of the United States of America. The Code was first published in 1926, and a new edition of the code has been published every six years since 1934. The 2012 edition of the Code incorporates laws enacted through the One Hundred Twelfth Congress, Second Session, the last of which was signed by the President on January 15, 2013. It does not include laws of the One Hundred Thirteenth Congress, First Session, enacted between January 2, 2013, the date it convened, and January 15, 2013. By statutory authority this edition may be cited "U.S.C. 2012 ed." As adopted in 1926, the Code established prima facie the general and permanent laws of the United States. The underlying statutes reprinted in the Code remained in effect and controlled over the Code in case of any discrepancy. In 1947, Congress began enacting individual titles of the Code into positive law. When a title is enacted into positive law, the underlying statutes are repealed and the title then becomes legal evidence of the law. Currently, 26 of the 51 titles in the Code have been so enacted. These are identified in the table of titles near the beginning of each volume. The Law Revision Counsel of the House of Representatives continues to prepare legislation pursuant to 2 U.S.C. 285b to enact the remainder of the Code, on a title-by-title basis, into positive law. The 2012 edition of the Code was prepared and published under the supervision of Ralph V. Seep, Law Revision Counsel. Grateful acknowledgment is made of the contributions by all who helped in this work, particularly the staffs of the Office of the Law Revision Counsel and the Government Printing Office"--Preface.




Visual Impairments


Book Description

When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.




The Making of the Pacemaker


Book Description

Wilson Greatbatch, an electrical engineer in Buffalo, NY, had a brilliant idea and the technical know-how to turn his idea into a practical device, for which millions of people today are grateful. This is the story of the first pacemaker by the man who invented it. Intrigued by electronics from the time he was a boy, Greatbatch earned a degree in electrical engineering from Cornell University. It was during his time at Cornell that he first became interested in the medical applications of electronic devices. He learned about the problem of heart blocking at Cornell and knew it was fixable in principle, but at the time the vacuum-tube technology was impractical for medical use. By the 1950s he was teaching at the University of Buffalo School of Electrical Engineering and the first silicon transistors had just been invented. While using one of the new $90 transistors on another project Greatbatch discovered by accident, as he describes it, the proper design for a blocking oscillator that he immediately knew would work as a pacemaker. He soon interested Dr. William Chardack, chief of surgery at the Veteran''s Administration Hospital in Buffalo, in the project, and by 1958 they were conducting animal experiments. Greatbatch quit his job and for the next two years devoted full-time in his wood-heated barn workshop to building one pacemaker after another. During this time he built fifty pacemakers, forty of which went into animal experiments. By 1960 he and a team of surgeons and engineers had gained enough knowledge from the trial and error of the animal experiments to feel ready to begin implanting the remaining ten devices in people. The first trials went well and Greatbatch''s device extended the lives of many of these seriously ill patients by decades. What followed were years of hard work refining the battery and electrode technology, marketing the pacemaker to an initially skeptical medical community, and keeping the company that manufactured the device profitable. Reminiscent of Edison''s many dogged attempts to find the right solution in pursuit of an ingenious idea, The Making of the Pacemaker is a human-interest story at its best and also an important firsthand account for the medical archives of an invention that today saves millions of lives.

Ocular Vascular Occlusive Disorders


Book Description

This book provides a comprehensive account of the pathogenesis, clinical features, and management of ocular vascular occlusive disorders, with the focus very much on the scientific evidence. This offers a sound basis for addressing the many controversies that surround these disorders, which collectively constitute the most common cause of visual impairment or blindness. The book is divided into two sections, the first of which addresses the basic science and encompasses vascular anatomy, blood supply and flow, and retinal tolerance time to acute ischemia. The second, clinical, section covers the presentation, clinical features, diagnosis, and treatment of the full range of vascular occlusive disorders of the retina, the choroid, the anterior segment of the eye, ophthalmic manifestations of carotid artery disease and the optic nerve. Ocular Vascular Occlusive Disorders, written by a distinguished world leader in the field, will be invaluable for general ophthalmologists, and particularly for retina specialists, neuro-ophthalmologists, and researchers.
