The Evolutionary Basis Of Strabismus And Nystagmus In Children

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.

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.

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.

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.

The 8 recurring volumes of the "Essentials in Ophthalmology" series cover the most recent developments in one of eight subspecialties in Ophthalmology. With four volumes published per year, each subspecialty is newly visited every 24 months, with a distinct focus on recent developments. By bridging the gap between original research and medical textbooks, the transfer of this developing knowledge into daily practice is greatly enhanced.

Based on Dr. Wright’s classic major reference, Handbook of Pediatric Strabismus and Amblyopia outlines the latest findings in diagnosing the most commonly presenting problems in pediatic cases, offering the most complete assessment tools for accurate diagnosis and then best treatment options. Distilling the essentials of these prevelant and sometimes complicated cases into a portable, complete and authorative pocket reference, this handbook offers a complete picture of how to best treat pediatric patients. Specifically, the introductory chapters on the specifics of pediatric ophthalmology (embryology, post-natal development and the pediatric exam) will help newcomers to pediatric practice fully grasp the subtle differences in pediatric care. The chapters are written by leading experts in the field and are presented in a user-friendly format, relying on heavily illustrated in color plates, clincally helpful tables, charts, and decision-making guidelines. This approach will enable the practitioner (whether specialist or generalist) to make the most accurate diagnosis and choose the most effective treatment option.

This case-based approach to the management of pediatric eye diseases and strabismus teaches the novice, as well as the experienced surgeon, how to conceptualize and analyze surgical planning to maximize patient outcomes, allowing readers to “get inside the head of the surgeon.” Individual cases with clear instructions and an abundance of color illustrations, presented by experts in the field, teach critical information one case at a time. Practical Management of Pediatric Ocular Disorders and Strabismus provides the key guiding principles of a traditional textbook in an easy-to-digest format. Each chapter of the text tackles a common or rare clinical situation and begins with the description of an illustrative case. The chapters are structured with sections on case description, differential diagnosis, management and outcomes with a list of possible complications and the approach to their management.
