John Dowling’s The Retina, published in 1987, quickly became the most widely recognized introduction to the structure and function of retinal cells. In this Revised Edition, Dowling draws on twenty-five years of new research to produce an interdisciplinary synthesis focused on how retinal function contributes to our understanding of brain mechanisms. The retina is a part of the brain pushed out into the eye during development. It retains many characteristics of other brain regions and hence has yielded significant insights on brain mechanisms. Visual processing begins there as a result of neuronal interactions in two synaptic layers that initiate an analysis of space, color, and movement. In humans, visual signals from 126 million photoreceptors funnel down to one million ganglion cells that convey at least a dozen representations of a visual scene to higher brain regions. The Revised Edition calls attention to general principles applicable to all vertebrate retinas, while showing how the visual needs of different animals are reflected in their retinal variations. It includes completely new chapters on color vision and retinal degenerations and genetics, as well as sections on retinal development and visual pigment biochemistry, and presents the latest knowledge and theories on how the retina is organized anatomically, physiologically, and pharmacologically. The clarity of writing and illustration that made The Retina a book of choice for a quarter century among graduate students, postdoctoral fellows, vision researchers, and teachers of upper-level courses on vision is retained in Dowling’s new easy-to-read Revised Edition.

A day-to-day guide on the diagnosis and management of routine to complex retinal disorders The diagnosis and treatment of retinal eye disorders often presents significant clinical challenges. The Retina Illustrated, edited by renowned retina specialist Justis Ehlers and an impressive group of worldwide contributors, provides a rapid-fire yet thorough approach to the visual world of retinal disease. Organized into ten sections and 102 succinct yet comprehensive chapters, this richly illustrated reference covers the full spectrum of retinal disorders, ranging from common degenerative diseases to emerging infectious retinal diseases. The book opens with a discussion of state-of-the-art diagnostic tools, followed by nine disorderspecific sections describing diagnosis and treatment of a wide-spectrum of retinal disorders, including degenerative, vascular, infectious, inflammatory, traumatic, oncology, and toxicities. The text covers the full age continuum, from conditions primarily impacting older adults, such as age-related macular degeneration and choroidal atrophy, to pediatric disorders, such as retinopathy of prematurity. Key Features Discussion of cutting-edge imaging diagnostics, including ultra-widefield angiography, intraoperative optical coherence tomography, and OCT angiography More than 400 high-quality illustrations augment the text, enhancing understanding of retinal disease, from symptoms and signs to differential diagnosis and management Reader-friendly format provides rapid assessment and review of numerous conditions This is a must-have reference for all providers who encounter patients with retinal disease, including general ophthalmologists, retina specialists, emergency medicine physicians, and optometrists. Ophthalmology residents and fellows-in-training will also find this book an invaluable education tool.

Pathologic Myopia is a major cause of severe vision loss worldwide. The mechanisms for vision loss include cataract, glaucoma, retinal detachment, and above all, myopic maculopathy within the posterior staphyloma. The first edition of Pathologic Myopia is one of the only current books to specifically address this disease and discusses recent developments in imaging technologies and various approaches to treatments, such as laser photocoagulation, photodynamic therapy, pharmaco-therapeutic injections in the vitreous, and surgery. This new edition is a timely update to the standard reference in the field, with new chapters on advanced refractive error correction, genetics, developing a classification system, and special surgical approaches for pathologic myopia. Complete with even more high-quality color images and informative tables, this book is written and edited by leaders in the field and is geared towards ophthalmologists, including residents and fellows in training, glaucoma and cataract specialists, and vitreoretinal macula experts.

This book addresses the issues relating to a wide variety of ocular diseases from which millions of people suffer. Long-term challenges include visual impairment and ocular blindness. Certain ocular diseases are quite rare, whereas others, such as cataracts, age-related macular degeneration (AMD), and glaucoma, are very common, especially in the aging population. A rapid expansion of new technologies in ocular drug delivery and new drug candidates, including biologics, to treat these challenging diseases in the retina and posterior segments of the eye have recently emerged. These approaches are necessary because the eye has many unique barriers to drug delivery. Thus, this timely reference Drug Delivery for the Retina and Posterior Segment Disease compiles and analyzes recent advances in the research and development of drug delivery systems for retina and posterior segment diseases of the eye, with an emphasis on the use of implantable devices, iontophoresis as well as micro- and nanoparticles.

Retinal Computation summarizes current progress in defining the computations performed by the retina, also including the synaptic and circuit mechanisms by which they are implemented. Each chapter focuses on a single retinal computation that includes the definition of the computation and its neuroethological purpose, along with the available information on its known and unknown neuronal mechanisms. All chapters contain end-of-chapter questions associated with a landmark paper, as well as programming exercises. This book is written for advanced graduate students, researchers and ophthalmologists interested in vision science or computational neuroscience of sensory systems. While the typical textbook's description of the retina is akin to a biological video camera, the real retina is actually the world’s most complex image processing machine. As part of the central nervous system, the retina converts patterns of light at the input into a rich palette of representations at the output. The parallel streams of information in the optic nerve encode features like color, contrast, orientation of edges, and direction of motion. Image processing in the retina is undeniably complex, but as one of the most accessible parts of the central nervous system, the tools to study retinal circuits with unprecedented precision are up to the task. This book provides a practical guide and resource about the current state of the field of retinal computation. Provides a practical guide on the field of retinal computation Summarizes and clearly explains important topics such as luminance, contrast, spatial features, motion and other computations Contains discussion questions, a landmark paper, and programming exercises within each chapter
