Nystagmus In Infancy And Childhood

This book describes, illustrates, and shares our current understanding, evaluation, and treatments of nystagmus in infancy and childhood. Nystagmus in Infancy and Childhood will provide clinicians with algorithms for examination, descriptions of diagnostic techniques, and medical, surgical, and alternative treatments of the visual system in infants and children with nystagmus.

Nystagmus in Infancy and Childhood is a highly-illustrative and thoughtfully written text that provides clinicians and scientists with detailed yet concise information regarding our current understanding, evaluation, and treatments of nystagmus in infancy and childhood. Throughout the text are clinical pearls and narrative observations intended to help the reader appreciate the enormous strides forward in the past 50 years of nystagmus research. Timely and comprehensive, this book is an "everything you need to know" resource, and will provide the reader with: - detailed methodologies of investigation, including analysis software, models of the ocular motor system, and current hypotheses regarding ocular motor oscillations - complementary appendices that can be used for special purposes, i.e., as clinical examination sheets, patient information sheets, and algorithm for computer analysis of nystagmus waveforms - new therapeutic approaches, using relevant eye-movement data and mechanisms - a roadmap toward a more rational, data-driven approach to the medical management of infantile nystagmus As the only resource effectively comprising the past 50 years of nystagmus research and therapeutic implications, Nystagmus in Infancy and Childhood will be a comprehensive and invaluable guide to for both clinicians and scientists who care for infants and children with nystagmus.

Pediatric Neuroophthalmology details the diagnostic criteria, current concepts of pathogenesis, neuroradiological correlates, and clinical management of a large group of neuroophthalmic disorders that present in childhood. Surprisingly distinct from neuroophthalmic disorders afflicting adults, this set of diseases falls between the cracks of most ophthalmology training, and thus, warrants a practical, clinical guide for the practitioner in ophthalmology - the neuroophthalmologist, pediatric ophthalmologist, general ophthalmologist - as well as neurologists and for residents. The authors, leading pediatric ophthalmologists, have taken this difficult subject matter and developed an accessible, user-friendly manual with a detailed approach to the recognition, differential diagnosis, and management of pediatric neuroophthalmologic disorders.

This text is a comprehensive collection and discussion of scientific essays that define the pathogenesis of common forms of pediatric strabismus and nystagmus in terms of their common evolutionary mechanisms. The goal of this book is to assemble these essays, to provide a definitive source for current clinicians to use along with follow up comments to help direct future scientific research in the field of pediatric ophthalmology. This book includes 20 original essays written by Michael C. Brodsky which mechanistically explain and unify such enigmatic conditions such as infantile esotropia, latent nystagmus, primary oblique muscle overreaction action, dissociated vertical divergence, infantile nystagmus, and intermittent exotropia in terms of ancestral evolutionary reflexes which become expressed in different ways to generate these disorders. This collection of essays is poised to become a classic reference, providing the necessary neurological framework for contextualizing unique ocular motor disorder and understanding the evolutionary mechanisms responsible for their development in early childhood. Written with focused interest for pediatric ophthalmologists and neuro-ophthalmologists, this reference will also find audience with ophthalmologists, neurologists, evolutionary biologists, and neuroscientists.

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.

This volume brings together work from leading researchers in the fields of developmental disorders of binocular vision, strabismus, and both infantile and acquired forms of nystagmus. It contains four sections. The first section, Basic Concepts of Stable Vision and Gaze, deals with psychophysical aspects of infantile forms of nystagmus and the relative contributions of extraocular proprioception and efference (corollary discharge). It also contains an accessible review of current notions of spatial and temporal visual functions and spatial constancy in infantile nystagmus syndrome and latent nystagmus. The second section, New Models and Techniques for Studying Gaze Stability, reviews animal and development models for strabismus, amblyopia, and nystagmus. It also contains novel optical methods for managing the visual consequences of nystagmus and a study of the potential ill effects of video displays on children's response to near viewing. The third section, New Therapies for Congenital Nystagmus, presents basic genetic studies and clinical trials of drug and surgical treatment of those patients with infantile forms of nystagmus. The final section,General Aspects of Normal and Abnormal Gaze Control, pulls together a range of contributions dealing with normal gaze control, infantile nystagmus, and acquired disorders of eye movements, including new treatment measures. This book will be a valuable resource for all scientists and practitioners interested in developmental disorders of vision.

This book takes a clinical approach to the patient with a genetic disease that affects the eye. The chapters on particular types of diseases follow the same organizational format, covering history, pathogenesis and etiology, epidemiology, classification, clinical manifestations and diagnosis, and treatment. The recent progress achieved in the molecular genetics of eye disease is fully reflected throughout the book. It is written by leading experts in the field and provides clinical, molecular genetic and management information on common and rare diseases. The chapters are heavily illustrated and provide a good Atlas for the practicing ophthalmologist or geneticist.

In this friendly guide, a girl called Amber explains all about her 'dancing eyes,' or nystagmus. Amber explains how children with nystagmus might need to read, learn or play differently, and what their families, school and friends can do to help. She invites readers to learn the causes and symptoms, to help others understand the condition and help increase the self-esteem and confidence of those who have it. This accessible guide for children aged 7+ is an excellent starting point for parents, teachers and other professionals working with children with nystagmus. It includes a practical checklist of easy adaptations to make school or home environments easier and more enjoyable for children with nystagmus, as well as a helpful list of recommended resources for additional support.
