This new edition has been fully revised to increase emphasis on instilling an understanding of the rationale of current practice from first principles, with summary tables of seminal studies and distilled guidelines from the RCOphth and NICE. This text will appeal to foundation doctors, specialist trainees in ophthalmology, candidates preparing for the Fellowship of the Royal College of Ophthalmology examination, and consultants and allied practitioners looking for a comprehensive yet accessible guide to the subject.

Blindness or serious vision impairment is one of the most feared disabilities known to humankind. A 2016 report compiled by the National Eye Institute (NEI) of the National Institutes of Health (NIH) and Prevent Blindness America states that although half of all blindness can be prevented, the number of people who suffer vision loss continues to increase. The technique of dynamic light scattering (DLS) was developed by physicists in the late 1960s to early 1970s. DLS is now emerging as a potential ophthalmic tool, making possible studies of virtually every tissue and fluid comprising the eye, thus pushing the envelope for broader applications in ophthalmology. This book presents a comprehensive review of the application of light scattering in clinical use. It is the first of its kind, offering insight to how DLS can be applied to the human eye as well as animals. Chapters discuss DLS in neurological diseases, including protocols, informed consent, and patents. Dynamic Light Scattering Spectroscopy of the Human Eye is a must-have resource for physicians, engineers, and physicists interested in the clinical application of DLS to diagnose and potentially treat medical conditions in a non-invasive, quantitative and novel way.

For the millions of people with untreatable blindness the thought of a visual prosthesis that would allow them to live a normal life has always been a distant hope. There have been intermittent bright spots that periodically fan that hope such as when Dr. Dobelle's visual prosthesis patient drove a car in an empty parking lot. This book will serve as an update of the work in developing a visual prosthesis. Chapters discuss the physiologic and engineering issues, alternative strategies, and patents, as well as recent research studies. Visual Prosthesis - A Concise Guide is a must-have resource for ophthalmologists, neurologists, engineers and physicists.

The introduction of the slitlamp of Gullstrand has opened to ophthalmology an entirely new field for clinical observation and diagnosis. It has created what may be . termed an "Histology of the living eye". . Normal and pathologie conditions heretofore established only anatomically can be directly observed in the living eye. lt shows us not only structures that are known, but in addition aseries of observations on histological details, heretofore impossible. These structures, owing partly to their delicacy. , were formerly sacrificed in the process of fixation, or it was impossible to further differentiate them by any method of staining. For instance, we have up to the present failed of anatomical proof of the numerous physiologio remnants of the tunica vasculosa lentis, the arteria hyaloidea, the various intricacies of the framework supporting the vitreous body, types of Jens sclerosis, eto. , but the number of facts already known as a result of anatomical research which have hitherto evaded clinical confirmation, is far greater, The slitlamp, in combination with the corneal microscope, perinits us to observe the living endothelium on the posterior surface of the cornea. Every individual endo- thelial cell on Descemet's membrane, as well as each pathologically deposited lympho- eyte is revealed. The nerve fibres of the cornea can be traced to their very finest ramifications. In Deseemet's and Bowman's membranes we have observed pathological folds,' manifested by their charaeteristic reflexes.

While the field of vision science has grown significantly in the past three decades, there have been few comprehensive books that showed readers how to adopt a computional approach to understanding visual perception, along with the underlying mechanisms in the brain. Understanding Vision explains the computational principles and models of biological visual processing, and in particular, of primate vision. The book is written in such a way that vision scientists, unfamiliar with mathematical details, should be able to conceptually follow the theoretical principles and their relationship with physiological, anatomical, and psychological observations, without going through the more mathematical pages. For those with a physical science background, especially those from machine vision, this book serves as an analytical introduction to biological vision. It can be used as a textbook or a reference book in a vision course, or a computational neuroscience course for graduate students or advanced undergraduate students. It is also suitable for self-learning by motivated readers. in addition, for those with a focused interest in just one of the topics in the book, it is feasible to read just the chapter on this topic without having read or fully comprehended the other chapters. In particular, Chapter 2 presents a brief overview of experimental observations on biological vision; Chapter 3 is on encoding of visual inputs, Chapter 5 is on visual attentional selection driven by sensory inputs, and Chapter 6 is on visual perception or decoding. Including many examples that clearly illustrate the application of computational principles to experimental observations, Understanding Vision is valuable for students and researchers in computational neuroscience, vision science, machine and computer vision, as well as physicists interested in visual processes.

In the past few years, there has been an explosion of eye movement research in cognitive science and neuroscience. This has been due to the availability of 'off the shelf' eye trackers, along with software to allow the easy acquisition and analysis of eye movement data. Accompanying this has been a realisation that eye movement data can be informative about many different aspects of perceptual and cognitive processing. Eye movements have been used to examine the visual and cognitive processes underpinning a much broader range of human activities, including, language production, dialogue, human computer interaction, driving behaviour, sporting performance, and emotional states. Finally, in the past thirty years, there have been real advances in our understanding of the neural processes that underpin eye movement behaviour. The Oxford Handbook of Eye Movements provides the first comprehensive review of the entire field of eye movement research. In over fifty chapters, it reviews the developments that have so far taken place, the areas actively being researched, and looks at how the field is likely to devlop in the coming years. The first section considers historical and background material, before moving onto section 2 on the neural basis of eye movements. The third and fourth sections looks at visual cognition and eye movements and eye movement pathology and development. The final sections consider eye movements and reading and language processing and eye movements. Bringing together cutting edge research from and international team of leading psychologists, neuroscientists, and vision researchers, this book is the definitive reference work in this field.

With predation and carnivory as catalysts, the first known eye appeared in a trilobite during the Cambrian explosion approximately 543 million years ago. This period was a crucible of evolution and teemed with anatomic creativity although the journey to formed vision actually began billions of years before that.
The Cambrian period, however, spawned nearly all morphologic forms of the eye, followed by descent over hundreds of millions of years providing an unimaginable variety of eyes with at least ten different designs. Some eyes display spectacular creativity with mirror, scanning or telephoto optics. Some of these ocular designs are merely curiosities, while others offer the finest visual potential packed into a small space, limited only by the laws of diffraction or physiological optics.
For example, some spiders developed tiny, well-formed eyes with scanning optics and three visual pigments; scallops have 40-100 eyes circling their mantle, each of which has mirror optics and contains two separate retinae per eye; deep ocean fish have eyes shaped like tubes containing yellow lenses to break camouflage; and some birds have vision five times better than ours; but this is only part of the story. Each animal alive today has an eye that fits is niche perfectly demonstrating the intimacy of the evolutionary process as no other organ could. The evolution of the eye is one of the best examples of Darwinian principles.
Although few eyes fossilize in any significant manner, many details of this evolution are known and understood. From initial photoreception 3.75 billion years ago to early spatial recognition in the first cupped eyespot in Euglena to fully formed camera style eyes the size of beach balls in ichthyosaurs, animals have processed light to compete and survive in their respective niches.
It is evolution's greatest gift and its greatest triumph. This is the story of the evolution of the eye.

This book includes the concept, general summary and the equipment of the visual electrophysiological examination. It also covers the clinical application scope, diagnosis protocol, standardized operation steps, clinical report samples, and the key points of reading reports, etc. of visual evoked potential (VEP), electroretinogram (ERG), electrooculogram (EOG), multifocal VEP, multifocal ERG and other commonly used visual electrophysiological examinations.

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.

Over the past decade there have been major advances in the management of patients with craniofacial trauma. These have been fuelled by new concepts and techniques arising from the elective repair of congenital craniofaciald deformities, and also by the increase in survival after trauma, due to improved resuscitation techniques. More radical approaches to complex problems have been achieved by multidisciplinary teams, with close collaboration between the neurosurgeon, maxillofacial surgeon, otorhinolaryngologist, ophthalmic, plastic, and accident and emergency surgeon. This book is the first to provide a multidisciplinary approach to the management of craniofacial trauma. Each section has been written by a specialist involved in craniofacial trauma, from the point of view of their own particular discipline, and presents vital information on the practical manamgement strategies.
