This second volume in a short series on the glaucomas is devoted to the two main types of the disease,…
open angle glaucoma and angle closure glaucoma. The contents are based on observations and experience gained during the management of more than 40,000 hospital and 7,000 private patients, with follow-up of 10 to 50 years. The book is comprehensive in scope. All aspects of diagnosis are carefully examined, surgical indications and techniques are explained, and the role of medical treatment is evaluated. Importantly, chapters are included on topics that are frequently overlooked in other books but are important to early diagnosis, such as diurnal pressure curve, HRT, and non-conventional perimetry. This volume provides a wealth of information and includes almost 1000 illustrations, the majority in color, as well as an accompanying DVD of surgical techniques. It will be an invaluable asset for all ophthalmologists.Par Arnab Biswas. 2014
Eyelid tumors are commonly encountered by oculoplastic as well as plastic surgeons. The challenge of managing these cases lies not…
only in performing the surgery in a precise manner in small area, but also in ensuring a visually-appealing cosmetic outcome. This is an innovative and concise portable handbook that guides the surgeons on how to approach and manage these cases in a step-by-step manner. Each chapter of this practical guidebook has outstanding illustrations drawn in full color clearly showing each incision line, flap management, suture placement and its technique and the expected cosmetic outcome. When a lid tumor is excised, there is a tissue defect that needs to be corrected. Ophthalmologists and plastic surgeons will find this work an excellent reference material to solve the jigsaw puzzle of tissue defects in and around the periorbital region. Importantly, they can quickly refer to the images just before starting a procedure. The author has first explained the anatomical aspects and anesthetic techniques for eyelid surgery, followed by review of the benign and malignant tumors, finally describing the flap creation and reconstruction techniques that are currently used in various lid tumors in an organized fashion.Par Livio Presutti, Francesco Mattioli. 2016

vision. Knowledge of the ocular toxicity of these drugs has increased during the past fifty years as their use has expanded. Hydroxychloroquine and Chloroquine Retinopathy is the first single-source book on the subject and is essential for the practicing ophthalmologists, rheumatologists, dermatologists, and internists who prescribe these drugs. It covers clinical topics such as signs and symptoms of toxicity, toxicity screening, ancillary testing, to whom and why the drugs are prescribed and dosing considerations. Additionally, the book addresses practice management considerations, including coding, reimbursement and equipment costs, and the medico-legal responsibilities of the rheumatologist and of the ophthalmologist. Guidelines for the management of hydroxychloroquine and chloroquine vary around the world and differences between the guidelines of the United Kingdom, the United States, and other countries are identified. The book concludes with a collection of case examples illustrating common clinical scenarios and their management. This book is a "must-have" resource for physicians who use these drugs.Par Moncef Khairallah, Soon-Phaik Chee. 2017
This book reviews the various emerging infectious diseases that show a significant association with uveitis, describing and explaining their ocular…
manifestations with the aid of color illustrations. In addition, it presents brief reports of further emerging infections that are associated with uveitis in rare cases. The coverage is wide ranging, encompassing diverse emerging bacterial, viral, parasitic and fungal infections. Individual chapters are also devoted to important re-emergent diseases such as syphilis and tuberculosis, with the focus on new data on epidemiology, diagnosis and management. Emerging infectious diseases are defined as "those whose incidence in humans has increased within the past two decades or threatens to increase in the near future". Emergence may be due to the spread of a new agent, to the recognition of an infection that has been present in the population but has gone undetected, or to the realization that an established disease has an infectious origin. This book will be an invaluable source of information on all aspects of uveitis in these diseases.Par Rudolf F. Guthoff, James A. Katowitz. 2010

Seeing Through New Eyes offers an accessible introduction to the treatment of visual dysfunction, a significant but neglected problem associated…
with autism spectrum disorders (ASDs) and other developmental disabilities. Dr. Kaplan identifies common ASD symptoms such as hand-flapping, poor eye contact and tantrums as typical responses to the confusion caused by vision disorder. He also explains the effects of difficulties that people with autism experience with "ambient vision", including a lack of spatial awareness and trouble with coordination. Other chapters give guidance on how to identify the visual deficits of nonverbal children, select prism lenses that will alter the visual field, and create individually tailored programs of therapy in order to retrain the system. This book is essential reading for parents of children with ASDs, and professionals in the fields of autism, optometry and ophthalmology, psychology and education.Par Thomas H. Williamson. 2013

vitreoretinal surgery. It provides a complete guide to all common vitreoretinal surgical procedures and also covers diagnosis and other aspects of management. The book is designed to allow a trainee or professional vitreoretinal surgeon to determine the best methodology in individual cases. In order to acquaint the reader with different opinions, "surgical pearls" have been contributed by other international experts in the field. These have proved popular in the past as an illustration of alternative methods, without detracting from the overall method described by the main author. Vitreoretinal Surgery will continue to prove particularly popular amongst trainees, but will also be of value to practicing professionals who need help in the management of difficult and rare cases. The text is backed up by the provision of videos of some aspects of the surgery.Par Beata Jastrzebska. 2015

personal and professional journey. Born blind, Schneider taught himself to see and developed an innovative program of healing and recovery that has helped thousands of people regain and improve their health. The exercises in this book will help you to create a basic eye health routine that you can immediately incorporate into your life. This program is not only strengthening but also restorative and deeply relaxing. You will learn how to reverse developing issues before they cause damage and how to remedy existing problems including near- and far-sightedness and lazy eye as well as cataracts, glaucoma, optic neuritis, detached retinas and tears, macular degeneration, and retinitis pigmentosa. Vision for Life is not only for people who see poorly and would like to improve their vision, but also for those with 20/20 vision who wish to maintain their perfect eyesight as they grow older.Clients of the Meir Schneider Self-Healing Method experience their own capacity to bring about recovery, reversing the progress of a wide range of degenerative conditions such as arthritis and muscular dystrophy as well as eye disease. Based in part on the established Bates Method of eyesight improvement and in part on his own professional and personal discoveries, Meir Schneider's pioneering approach has helped thousands of people successfully treat a host of eye problems, including nearsightedness, farsightedness, astigmatism, lazy eye, double vision, glaucoma, cataracts, macular degeneration, retinal detachment, retinitis pigmentosa, and nystagmus.Born blind to deaf parents, Schneider underwent a series of painful operations as a young child and was left with ninety-nine percent scar tissue on his eyes, resulting in his being declared incurably blind. At the age of seventeen, he discovered how to improve his vision from one percent to fifty-five percent of normal vision with the eye exercises presented in this book. Today Schneider drives a car, reads, and proves time and again that vision can and does improve with exercise. His contributions to the field of self-healing are recognized by alternative health practitioners and medical doctors alike.From the Trade Paperback edition.Par Nora V. Laver, Charles S. Specht. 2017
