Download or read book Optic Disorders and Visual Field written by Ningli Wang and published by Springer. This book was released on 2019-03-01 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses more than one hundred patients in which visual pathway is involved, and focuses on the role of visual field examination in the diagnosis of these diseases. It also highlights the application of concepts from the new interdiscipline, integration medicine as well as molecular biology and genetics in the analysis of the diseases. In this book, the commonly (typically) noticed changes in the visual field of patients with visual pathway disorders are mainly described in the chapter one titled as “Visual Field-related Anatomy of Visual Pathway” and chapter two titled as “Interpretation of Visual Field Test”, while the majority of the cases presented with "atypical" changes in visual field. At this point, the changes in the visual field could function as either a key to understand the disease, or a question mark which confuses the diagnosis. However, the process of pushing aside a fog around the diagnosis step by step helps the readers to gradually disclose the essence of the disease.

Download or read book Resolving Dilemmas in Perimetry written by Sagarika Patyal and published by Springer Nature. This book was released on 2021-07-22 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers interpretation of visual fields by Humphrey and Octopus perimeters and discussion of Humphrey visual fields in a variety of ocular disorders.It examines dilemmas faced by an ophthalmologist while evaluating visual fields which do not match with the clinical picture. Glaucoma, the commonest condition for visual field investigation is discussed in detail. Logical reasoningfor incorporating perimetry in glaucoma management with a clear understanding of the challenges in its interpretation is delved into. The book progresses to advanced glaucoma and glaucoma progression. It discusses a systematic evaluation of various parts of the visual field so that the reader can make a calculated management plan for their patient. Each chapter attempts to clearly enunciate factors that help in the diagnosis and features which may be confused with other conditions. Fields which help diagnosing early, advanced glaucoma and glaucoma progression with images and methods of ensuring reasonable diagnostic accuracy are included. The book incorporates separate chapters on ocular conditions which also mimic visual field defects of glaucoma with detailed modes of correct diagnosis, diagnostic dilemmas arising from retinal, macular, vascular, visual pathway lesions mimicking visual field defects of glaucoma or while coexisting with glaucoma, supported by algorithms to achieve a quick diagnosis in a busy OPD without missing the clinical findings and by using minimal investigative modalities. This book helps clinicians to prevent over diagnosis or under diagnosis of glaucoma and helps diagnose cases with morbidities causing visual field defects.
Download or read book Visual Impairments written by National Research Council and published by National Academies Press. This book was released on 2002-08-17 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Revolutionizing Tropical Medicine written by Kerry Atkinson and published by John Wiley & Sons. This book was released on 2019-08-27 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive resource describing innovative technologies and digital health tools that can revolutionize the delivery of health care in low- to middle-income countries, particularly in remote rural impoverished communities Revolutionizing Tropical Medicine offers an up-to-date guide for healthcare and other professionals working in low-resource countries where access to health care facilities for diagnosis and treatment is challenging. Rather than suggesting the expensive solution of building new bricks and mortar clinics and hospitals and increasing the number of doctors and nurses in these deprived areas, the authors propose a complete change of mindset. They outline a number of ideas for improving healthcare including rapid diagnostic testing for infectious and non-infectious diseases at a point-of-care facility, together with low cost portable imaging devices. In addition, the authors recommend a change in the way in which health care is delivered. This approach requires task-shifting within the healthcare provision system so that nurses, laboratory technicians, pharmacists and others are trained in the newly available technologies, thus enabling faster and more appropriate triage for people requiring medical treatment. This text: Describes the current burden of communicable and non-communicable diseases in low- to middle-income countries throughout the world Describes the major advances in healthcare outcomes in low-to middle-income countries derived from implementation of the United Nations/World Health Organisation’s 2000 Millennium Development Goals Provides a review of inexpensive rapid diagnostic point-of-care tests for infectious diseases in low-resource countries, particularly for people living in remote rural areas Provides a review of other rapid point-of-care services for assessing hematological function, biochemical function, renal function, hepatic function and status including hepatitis, acid-base balance, sickle cell disease, severe acute malnutrition and spirometry Explores the use of low-cost portable imaging devices for use in remote rural areas including a novel method of examining the optic fundus using a smartphone and the extensive value of portable ultrasound scanning when x-ray facilities are not available Describes the use of telemedicine in the clinical management of both children and adults in remote rural settings Looks to the future of clinical management in remote impoverished rural settings using nucleic acid identification of pathogens, the use of nanoparticles for water purification, the use of drones, the use of pulse oximetry and the use of near-infrared spectroscopy Finally, it assesses the potential for future healthcare improvement in impoverished areas and how the United Nations/World Health Organization 2015 Sustainable Development Goals are approaching this. Written for physicians, infectious disease specialists, pathologists, radiologists, nurses, pharmacists and other health care workers, as well as government healthcare managers, Revolutionizing Tropical Medicine is a new up-to-date essential and realistic guide to treating and diagnosing patients in low-resource tropical countries based on new technologies.

Download or read book Neuro Ophthalmology written by Matthew J. Thurtell and published by Oxford University Press, USA. This book was released on 2012 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuro-ophthalmology is a field of medicine that touches on every subspecialty in neurology, but has an undeserved reputation as a branch of knowledge that is difficult to learn and practice. Many neurologists and ophthalmologists do not receive sufficient exposure to neuro-ophthalmology during their residencies, and are uncomfortable diagnosing and treating patients with neuro-ophthalmic problems. Authored by neuro-ophthalmologists whose careers span three generations in the field, Neuro-Ophthalmology helps clinicians evaluate and manage patients with neuro-ophthalmic problems. This "curb-side consult" approach is divided into five sections: afferent (visual) disorders; efferent (eye movement) disorders; eyelid disorders; pupil disorders; and combination syndromes. Based on the most current scholarly evidence and filled with practical advice, Neuro-Ophthalmology provides the answers to "what do I do now?"

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.
Download or read book Making Eye Health a Population Health Imperative written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-15 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
