Ophthalmologists are often the first clinicians to evaluate a patient harboring an underlying intraorbital or intracranial structural lesion. This unique position makes it particularly important for them to understand the basic mechanics, indications, and contraindications for the available orbital and neuroimaging studies (e.g., CT and MR imaging), as well as any special studies that may be necessary to fully evaluate the suspected pathology. It is equally important for them to be able to communicate their imaging questions and provide relevant clinical information to the interpreting radiolo

The optic nerve is a primary reference for those ophthalmologists and researchers interested in its anatomy and physiology, in the most recent diagnostic techniques, as well as in the clinical management of optic nerve disorders. The book provides a detailed description of the structure and functioning of the optic nerve and attempts at clarifying how anomalies in its development are related with tumor development. The book surveys the most recent diagnostic techniques, such as spectral domain optical coherence tomography, and highlights how these techniques can be employed to evaluate optic nerve layers as well as lesions compressing the visual pathway. Practical references to optic nerve drusen and the changes in the optic nerve due to diabetic retinopathy are also presented. The book is written in a concise fashion and aims at being a major reference to a broad audience, including students, ophthalmologist consultants, neurologists, researchers, and surgeons concerned with optic nerve diseases.

Dr. Jonathan J. Dutton, a world leader in orbital surgery, presents Radiology of the Orbit and Visual Pathways. This new and unique diagnostic guide offers expert advice on the full spectrum of uses of CT and MRI, the two core methods of radiologic imaging of the orbit. An atlas style approach provides the essential text you need to accurately diagnose over 120 of the more common disorders you'll come across in your daily routine, and over 1,100 lavish illustrations enhance your visual guidance. Covering the entire visual pathways from the eye to the occipital cortex, you'll gain thorough k

Considerable evidence exists that visual sensory information is analyzed simultaneously along two or more independent pathways. In the past two decades, researchers have extensively used the concept of parallel visual channels as a framework to direct their explorations of human vision. More recently, basic and clinical scientists have found such a dichotomy applicable to the way we organize our knowledge of visual development, higher order perception, and visual disorders, to name just a few. This volume attempts to provide a forum for gathering these different perspectives.

Binocular vision is achieved by five neurovisual systems originating in the retina but varying in their destination within the brain. Two systems have been widely studied: the retino-tectal or retino-collicular route, which subserves an expedient and raw estimate of the visual scene through the magnocellular pathway (Isa, 2002), and the retino-occipital or retino-cortical route, which allows slower but refined analysis of the visual scene through the parvocellular pathway (Espinosa & Stryker, 2012). But there also exist further neurovisual systems: the retino-hypothalamic, retino-pretectal, and accessory optic systems, which play a crucial role in vision though they are less understood ...The focus of this issue is to review the most recent findings in brain imaging and neurophysiology of binocular vision and coordination in humans and animals with frontally-placed eyes. The emphasis will be put on studies that enable transfer of knowledge toward visual training programs targeting binocular functional disorders (e.g., amblyopia) and visual field defects (e.g., hemianopia).

Building on the successful formula of the first edition, Martin Tovée offers a concise but detailed account of how the visual system is organised and functions to produce visual perception. He takes his readers from first principles; the structure and function of the eye and what happens when light enters, to how we see and process images, recognise patterns and faces, and through to the most recent discoveries in molecular genetics and brain imaging, and how they have uncovered a host of new advances in our understanding of how visual information is processed within the brain. Incorporating new material throughout, including almost 50 new images, every chapter has been updated to include the latest research, and culminates in helpful key points, which summarise the lessons learnt. This book is an invaluable course text for students within the fields of psychology, neuroscience, biology and physiology.

The duplicity theory of vision concerns the comparisons (both differences and similarities) and interaction between the cone and rod systems in the visual pathways, with the assumption that the cone system is active during daylight vision and the rod system functions in low light (night time). Research on this aspect of vision dates back to the 17th century and the work of Newton, and is still ongoing today. This book describes the origin and development of this fundamental theory within vision research - whilst also examining the Young-Helmholtz trichromatic colour theory, and the opponent colour theory of Hering - and presents evidence and ideas in light of modern conceptions of the theory. Written for academic researchers and graduate students, the book brings back knowledge of the tradition of duplicity theory, inspiring questions related to anatomy, comparative biology, molecular biology, photochemistry, physiology, genetics, phylogenetics and psychophysics.

A comprehensive guide to current research, reflecting recent technical breakthroughs that have established the usefulness of the mouse model as part of a bilateral exchange between experimental and clinical research. Recent years have seen a burst of studies on the mouse eye and visual system, fueled in large part by the relatively recent ability to produce mice with precisely defined changes in gene sequence. Mouse models have contributed to a wide range of scientific breakthroughs for a number of ocular and neurological diseases and have allowed researchers to address fundamental issues that were difficult to approach with other experimental models. This comprehensive guide to current research captures the first wave of studies in the field, with fifty-nine chapters by leading scholars that demonstrate the usefulness of mouse models as a bridge between experimental and clinical research. The opening chapters introduce the mouse as a species and research model, discussing such topics as the mouse's evolutionary history and the mammalian visual system. Subsequent sections explore more specialized subjects, considering optics, psychophysics, and the visual behaviors of mice; the organization of the adult mouse eye and central visual system; the development of the mouse eye (including comparisons to human development); the development and plasticity of retinal projections and visuotopic maps; mouse models for human eye disease (including glaucoma and cataracts); and the application of advanced genomic technologies (including gene therapy and genetic knockouts) to the mouse visual system. Readers of this unique reference will see that the study of mouse models has already demonstrated real translational prowess in vision research.

First published in 1995, this book presents a model for understanding the visual processing underlying perception and action, proposing a broad distinction within the brain between two kinds of vision: conscious perception and unconscious 'online' vision.
