This text presents the range of clinical problems encountered by ophthalmologists in managing patients with diabetic retinopathy and provides an evidence-based approach to solving these problems. The unique features of the book include exposition with the perspective of evidence-based medicine. Exposition is grounded with clinical examples, and questions and discussions follow chapters to encourage thinking about problematic situations and areas of controversy. It also incorporates a wealth of information from the Diabetic Retinopathy Clinical Research network. The increasing frequency of diabetic patients in ophthalmic practice makes this a timely and practical reference for ophthalmologists and retina specialists.
The Neurology of Eye Movements provides clinicians with a synthesis of current scientific information that can be applied to the diagnosis and treatment of disorders of ocular motility. Basic scientists will also benefit from descriptions of how data from anatomical, electrophysiological, pharmacological, and imaging studies can be directly applied to the study of disease. By critically reviewing such basic studies, the authors build a conceptual framework that can be applied to the interpretation of abnormal ocular motor behavior at the bedside. These syntheses are summarized in boxes, new figures, schematics and tables. Part I discusses the visual need and neural basis for each functional class of eye movements. Part II deals with the evaluation of double vision, and systematically examines how many disorders of the central nervous system affect eye movements. This definitive new edition has been extensively rewritten and contains many new figures and an up-to-date section on the treatment of abnormal eye movements such as nystagmus. Insights and techniques from current research, case examples, bedside and laboratory studies and thousands of references are all available here from two recognized authors in the field. This volume is a must for understanding movement disorders. A major innovation has been development of a CD-ROM that offers hypertext links (which bridge basic science to clinical issues), and viewing of disorders of eye movements via over 45 video clips.
The aim of Atlas of Fundus Fluorescein Angiographyis to have a comprehensive book on the fluorescein angiographic findings in different disorders, so as to help the reader in understanding the disorder and in managing these types of cases.
From the Back Cover
Fundus fluorescein angiography has played a crucial role in the understanding of different disease processes affecting the eye. A good knowledge of the changes occurring in the fluorescein angiogram is important for correct diagnosis and management of eye disorders. With this in mind, cases seen at Sankara Nethralaya are published here in the form of an atlas. The aim of Atlas of Fundus Fluorescein Angiography is to have a comprehensive book on the fluorescein angiographic findings in different disorders, so as to help the reader in understanding the disorder and in managing these types of cases and to introduce images from pattern recognition by clinicians to use in their practice, to enable a more accurate diagnosis, and in turn, to offer patients a more appropriate and effective treatment. The authors have introduced new insight into pathophysiological mechanism of disease in the ocular fundus and offered unusual and challenging images which enhance appreciation of these peculiar diseases.
The book has been divided into seven major sections (Getting Started, Macular Disorders, Vascular Disorders, Inflammatory Disorders, Heredomacular Dystrophy, Optic Nerve Disorders, Tumors) with separate color coding for ease of use and with as many representativecases as possible.
This concise source for the clinical anatomy of the visual system covers the clinical anatomy of the eye, its adnexa, and the visual pathways in a well-illustrated, well-referenced format. It balances histologic content of the microscopic anatomy with functional aspects of the eye and visual system. Clear illustrations complement the text and provide clinical information on diseases and disorders that represent departures from normal clinical anatomy. * Full color illustrations throughout enhance the anatomical and clinical information. * The only anatomy text written by an optometrist for optometrists and students – it provides a strong foundation for recognizing and understanding clinical situations,problems, and treatments.

The subject of the book is the grounding of architectural acoustics in psychophysics (perception, listener preferences) and neuroscience (auditory function, neural correlates of perception and preference). This is the first rational-scientific approach to designing performance spaces that is based on systematic psychoacoustical observations of spatial hearing and listener preferences. Observations of the neuronal correlates of auditory qualities and listener preferences ground the theory of listener preferences in the neurophysiology of the human brain. A correlation-based model of neuronal signal processing in the central auditory system is proposed. Observed psychological and neurophysiological commonalities between auditory and visual sensations and preference patterns are presented and discussed. This book thus spans the disciplines of physics, acoustics, psychology, neurophysiology, and music production, thereby blending science and art.
Temporal and spatial sensations. Temporal auditory sensations include auditory qualities such as pitch, timbre, loudness, and duration, which are modeled using features extracted from the temporal autocorrelation function (ACF) of the sound. Neuronal responses related to these qualities are mainly associated with left hemisphere auditory regions of cerebral cortex. Spatial auditory sensations include the perceived direction of sound, its apparent size (apparent source width, ASW) and its subjective diffuseness deeply related to envelopment. These spatial aspects of sound perception are extracted from the interaural crosscorrelation function (IACF), which takes into account the differences in the sounds that reach the two ears. Cortical neuronal responses related to spatial hearing are mainly associated with auditory regions in the right hemisphere.
Thus, the “primary sensation” evoked by a sound in some space can be divided into two categories: temporal sensations and spatial sensations. Any other subjective responses of the source sound signal and the sound field can be described in terms of temporal and spatial factors. Part I of the book describes experimental results from basic research in acoustics, psychoacoustics, the psychology of auditory preferences, and auditory neurophysiology. Applications include optimal design of concert hall and opera house acoustics, architectural acoustics of speech intelligibility and musical expression, as well as the perception of noise and its annoyance.
In Part II, temporal and spatial sensations in vision are described in terms of similar kinds of correlation-based representations. A seamless, general theory can be established for temporal and spatial aspects of vision that includes subjective preferences for visual environments. Many audio-visual analogies are drawn. A typical temporal sensation of vision is the “pitch” of a flickering light, for which the missing fundamental is perceived in a manner highly analogous to its acoustic counterpart. Visual spatial sensations include contrast, regularity and coarseness. A spatial “vibrato” in a drawing is demonstrated as an application of the theory in the visual arts.
The reader is given a highly fleshed out strategy for architectural acoustical design that is grounded both in psychology and neuroscience. Few other works are as ambitious in attempting to understand and explain such a wide range of perceptual phenomena. This human-centered design approach can be applied to any design practice in which the goal is to optimize the experience of the design product by its users. The proposed theory shows how a unified science of human perceptual experience and preference might be both possible and useful.
The 8 recurring volumes of the “Essentials in Ophthalmology” series cover the most recent developments in one of eight subspecialties in Ophthalmology. With four volumes published per year, each subspecialty is newly visited every 24 months, with a distinct focus on recent developments. By bridging the gap between original research and medical textbooks, the transfer of this developing knowledge into daily practice is greatly enhanced. This volume focuses on retinal imaging, a quickly evolving field with numerous advances like Optical Coherence Tomography (OCT).
