By activating your unique access code, you can discover more than 200 videos, view and enlarge nearly 250 high resolution images, and annotate the work for future personal reference. The Neurology of Eye Movements, edition 5 has two interrelated parts. The first comprises a modern synthesis of the anatomical, physiological, and pharmacological substrate for eye movements, including current views on the reflexive and voluntary control of gaze. This synthesis is based on electrophysiological and inactivation studies in macaque, and behavioural studies in humans that incorporate functional imaging and transcranial magnetic stimulation (TMS) in normals, and clinicopathological studies in patients with neurological, visual, or vestibular disorders. Sophisticated experimental paradigms have been applied to both species to explore aspects of cognition, memory, volition, and reward. This large body of research has demonstrated the power of eye movements as experimental tools. The second part of the book applies this synthesis to the clinical and laboratory evaluation of patients with abnormal eye movements due to a broad range of disorders - from muscular dystrophy, and genetic disorders, to dementia, including visual and vestibular conditions. By placing links to figures, tables, boxes, and videos, a synthesis of basic research and clinical findings is provided, that may shed new light on disease processes and provide insights on normal brain function.

Clinical Anatomy of the Eye has proved to be a very popular textbook for ophthalmologists and optometrists in training all over the world. The objective of the book is to provide the reader with the basic knowledge of anatomy necessary to practice ophthalmology. It is recognised that this medical speciality requires a detailed knowledge of the eyeball and the surrounding structures. The specialista s knowledge should include not only gross anatomic features and their development, but also the microscopic anatomy of the eyeball and the ocular appendages. The nerve and blood supply to the orbit, the autonomic innervation of the orbital structures, the visual pathway, and associated visual reflexes should receive great emphasis. The practical application of anatomic facts to ophthalmology has been emphasised throughout this book in the form of Clinical Notes in each chapter. Clinical problems requiring anatomic knowledge for their solution are presented at the end of each chapter. Illustrations are kept simple and overview drawings of the distribution of the cranial and autonomic nerves have been included.

This richly illustrated book is intended as a gold standard for the refractive surgeon. It complements the authors' successful previous book, Management of Complications in Refractive Surgery, by providing detailed practical information on the management of specific cases. Worldwide leaders in the field document a wide range of challenging cases drawn from their own clinical practice. These cases relate to the planning of refractive laser treatment; intra operative complications when using LASIK (Microkeratome and Femtosecond) and various surface treatments, including PRK, PTK and EpiLASIK; early and late postoperative complications with these treatments and a range of other complications that may arise during or after refractive surgery. This book will be an indispensable aid for the refractive surgeon and will assist in decision making when the surgeon is confronted by a difficult case.

La V edizione di Neuroftalmologia ora anche in versione digitale. Il volume considera i più recenti aggiornamenti clinico-scientifici nell'ambito delle neuroscienze. Tale approccio consente, da un lato, un'ulteriore definizione dei quadri clinici della neuroftalmologia; dall'altro, grazie all'imaging e alla biologia molecolare una loro più precoce diagnosi. I dispositivi, tuttavia, devono essere sempre supportati dalla conoscenza dei sintomi clinici neuroftalmologici che possono manifestarsi in maniera isolata. Una diagnosi precoce è affidata alla preparazione e attenzione clinica del neuroftalmologo, in un approccio multidisciplinare che consideri varie specificità e competenze. Il volume è uno strumento di consultazione rilevante, perché fornisce indicazioni sulla necessaria visione interdisciplinare nella gestione del paziente neuroftalmologico. Il paziente può essere seguito al meglio da un'equipe medica multidisciplinare che comprenda oftalmologo, neurologo, otorinolaringoiatra, neuroradiologo, neurochirurgo, internista immunologo e chirurgo maxillofacciale (solo per elencare le principali specialistiche coinvolte nel percorso diagnostico-terapeutico di tali pazienti).
