This is a reference text for both the novice and the accomplished ophthalmic surgeon. The book imparts basic information on tissue tactics and knot tying and demonstrates the applicability of these techniques to various microsurgical situations, in both the anterior and the posterior segment of the eye. Illustrated with photos and line drawings, each chapter contains sections on: Surgical indications, Instrumentation and equipment, Surgical technique, Complications and future challenges.

The new edition of this comprehensive text continues to provide a detailed and up-to-date account of research on visual perception, while maintaining the emphasis of earlier editions on the functional context of vision. Reflecting recent theoretical developments, the book is organised around the distinction between two broad functions of vision, to provide awareness and to control action.
In Part I, the account of visual processing in the brain has been extensively updated, and evidence from neuroimaging and neuropsychology has been integrated into a critical account of the 'two pathways' theory of visual cortex. The revision of chapters in Part II has given particular attention to recent advances in integrating psychophysical, physiological and computational approaches to problems such as the perception of surfaces and of motion. With the help of new illustrations, full introductions are provided to the key mathematical concepts used in these areas. In Part III, three new chapters draw on evidence from both animal and human behaviour to cover optic flow and locomotion, the timing of actions, and perception of the social world. The concluding chapter considers critically the wider theoretical implications of the distinction between awareness and action as separate functions of vision.
Visual Perception, Fourth Edition will be an invaluable resource for both undergraduate and postgraduate students of psychology, biology, physiology and neuroscience, as well as researchers in the fields of visual neuroscience, visual perception and animal behaviour.

Optical Coherence Tomography represents the ultimate noninvasive ocular imaging technique although being in the field for over two-decades. This book encompasses both medical and technical developments and recent achievements. Here, the authors cover the field of application from the anterior to the posterior ocular segments (Part I) and present a comprehensive review on the development of OCT. Important developments towards clinical applications are covered in Part II, ranging from the adaptive optics to the integration on a slit-lamp, and passing through new structural and functional information extraction from OCT data. The book is intended to be informative, coherent and comprehensive for both the medical and technical communities and aims at easing the communication between the two fields and bridging the gap between the two scientific communities.

OCT is a relatively new imaging technique that is becoming increasingly popular among ophthalmologists in both private and academic settings. Imaging has been a slow moving area in ophthalmology for some time, but now OCT is providing another, more detailed source of demonstrable change in the eye, in diagnostic, therapeutic or post-surgical setting. OCT and ultrasound both measure advancing disease states and post surgical healing. The difference is that OCT shows more subtle changes, particularly post-surgically.

This book is exceptional in explaining not only when and how but also why vitrectomy is performed - an additional focus that will help trainee surgeons to develop their own critical thinking. Uniquely, the book's first part describes "the life of the vitreoretinal surgeon" to help residents decide whether the field is indeed suitable for them, and if yes, how they can chart their own course in the absence of a formal fellowship program. The second and third parts discuss the fundamentals in VR surgery, such as the general philosophy underlying vitrectomy, equipment, examination, timing, anesthesia, the surgeon's posture, and the organization of the operating room. The final two parts are dedicated to surgical strategy and tissue tactics, reviewing the principles of surgical maneuvers and the practical sides of diagnosis-specific issues. An appendix is also included, which offers additional guideposts for the aspiring trainee surgeon, including a description of how an ideal mentor should act in surgery. The book is written in an easy-to-follow format with bullet points and text boxes, and has well over 250 color images and line drawings as well as over 60 tables.

This book serves as an introductory reference on clinical aspects of glaucoma and myopia, providing essential guidelines for diagnosis and monitoring of glaucoma progression in patients, especially those with high myopias. Many clinical studies are presented by leading experts in the field in an accessible style, making the content suitable not only for ophthalmologists but also for optometrists and certified orthoptists as well as for students. The relation between myopia and glaucoma has been the subject of many clinical trials and population-based studies. Most of the data has suggested that moderate to high myopia is associated with increased risk of primary open-angle glaucoma, normal tension glaucoma, and ocular hypertension. There are several factors involved in the diagnosis of glaucoma, but it is often difficult to determine the presence of glaucoma in myopic eyes. A myopic eye, especially in cases of moderate to high myopia, tends to have a thin retina and choroid and to appear thinner than normal. Even with new imaging technologies with improved sensitivity and specificity for detecting glaucoma, each technology presents some challenges when assessing myopic eyes. This book furnishes an overview of these diagnostic challenges with reference to the growing prevalence and severity of myopia in various parts of the world, providing many valuable hands-on reports and clinical studies by authoritative authors. This knowledge will help to do away with the vague area between high myopia and glaucoma faced by clinicians.

Contains the proceedings of the XVI International Symposium on Retinal Degeneration (RD2014), to be held July 13-18, 2014 at the Asilomar Conference Center in Pacific Grove, California. A majority of those who will speak and present posters at the meeting will contribute to this volume. The Symposium addresses the blinding diseases of inherited retinal degenerations, which have no effective treatments and age-related macular degeneration, which has no cures, despite the fact that it is an epidemic among the elderly, with 1 in 3-4 affected by the age of 75. The RD2014 Symposium will focus on the exciting new developments aimed at understanding these diseases and providing therapies for them. The volume will present representative state-of-the-art research in almost all areas of retinal degenerations, ranging from cytopathologic, physiologic, diagnostic and clinical aspects; animal models; mechanisms of cell death; molecular genetics; and developing potential therapeutic measures such as gene therapy and neuroprotective agents for potential pharmaceutical therapy; and several sight restoration approaches, including optogenetics. While advances in these areas of retinal degenerations will be included, several new topics either were in their infancy or did not exist at the time of the last RD Symposium, RD2012. These include many new developments in sight restoration using optogenetics, retinal or RPE cell transplantation, stem cell approaches and visual prosthetic devices. In addition, major advances will be presented in other basic mechanisms in age-related macular degeneration, several new aspects of gene and antioxidant therapy and revolutionary new imaging and functional testing that will have a huge impact on the diagnosis and following the course of retinal degenerations, as well as to provide new quantitative endpoints for clinical trials. The retina is an approachable part of the central nervous system (CNS), and there is a major interest in neuroprotective and gene therapy for CNS diseases and neurodegenerations, in general. It should be noted that with successful and exciting initial clinical trials in neuroprotective and gene therapy, including the restoration of sight in blind children, the retinal degeneration therapies are leading the way towards new therapeutic measures for neurodegenerations of the CNS. Many of the successes recently reported in these areas of retinal degeneration sprang from collaborations established at previous RD Symposia, and many of those will be reported at the RD2014 meeting and included.

Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-sectional pictures of the retina, the light-sensitive tissue lining the back of the eye (eyeSmart).
