Most Optometrists don't perform medical eye services, certainly not exclusively. You can develop a successful practice while providing a much needed service by bucking this trend. Jeffrey Sedgewick, O.D., M.D. spent 4 years as a practicing Optometrist prior to entering medical school. While practicing as an Optometrist and as an Ophthalmologist, he has seen many examples of poor medical care by Optometrists, himself included. He is convinced that it doesn't have to be this way. He believes Optometrists who start their own Medical Optometry Practice can fill an increasingly important function, but they need more knowledge and clinical experience, which he seeks to provide in this textbook, in his web site www.theodmdconsultinggroup.com, in future courses and as a consultant to your Medical Optometry Practice.

Neurological disorders are very common. They account for more than 10 percent of all diseases in West European countries and North America, and they result in 15 to 20 percent of all admissions to acute medical wards. Yet only a minority of patients are seen by a neurologist during their hospitalization. As most patients with neurological disorders are treated by nonspecialists, a good-working knowledge of the common neurological disorders is essential for medical students and all medical practitioners irrespective of their specialization. Most neurology textbooks are too detailed and also devote large sections to rare, obscure syndromes that have little relevance to practitioners outside the speciality of clinical neuroscience. The purpose of this book is to focus on the common neurological disorders that most clinicians are likely to see in their everyday clinical practice and to provide up-to-date and concise information. The book consists of fifteen chapters that cover what I believe is the essential knowledge required by a medical student and by practitioners not specializing in neurology. It is hoped that senior medical students, doctors in training, and clinicians not specializing in neurology will find this book a useful resource.

does not vary more than 1 % over the whole surface. Stimulus: The luminance of the stimuli can be regulated by means of neutral density filters. These filters are neither entirely neutral nor completely uniform, but these variations are not significant for perimetry. The maximum luminance of the stimuli is standardized at 1000 asb (316 2 cd.m-). The standard GP for kinetic perimetry has 3 neutral density filters which reduce the luminance by 0.5, 1.0 and 1.5 log units respectively. The modification of the GP for static perimetry is supplied with an additional series of four neutral density filters, which allow luminance steps of 0.1, 0.2, 0.3 and 0.4 log units. The resulting luminance values, expressed in apostilb, are given in Table I.

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.

Visual Fields via the Visual Pathway presents the varying visual field deficits occurring with lesions of the visual pathway. The book covers anatomy, pathology and signs and symptoms, plus visual field defects associated with specific parts of the visual pathway. Also covered is the basic theory of visual field assessment.This new edition includes
