The Eye, Volume 4: Visual Optics and the Optical Space Sense provides a well-integrated and authoritative account of the physiology of the eye. The book is organized into two parts. Part I on visual optics begins with a discussion of the branches of optics and the basic principles of geometrical optics. This is followed by separate chapters on refraction at plane and spherical surfaces; the thin spherical lens in air; reflexion at plane and spherical surfaces; the astigmatic lens; aberrations of optical images; ametropia and its correction; and retinoscopy and ophthalmoscopy. Part II on the optical space sense includes discusses of objective and subjective space; spatial localization according to direction; perception of distance and of size; spatial localization through binocular vision; special topics in binocular spatial localization; and ocular dominance and binocular retinal rivalry. Whilst the emphasis has been on readability rather than exhaustiveness, the various accounts are sufficiently well documented to make the treatise valuable not only to teachers in physiology, psychology and ophthalmology, but also to research workers in all branches of ocular physiology.

A renewed interest in the study of vision has attracted scholars from such diverse fields as neuroscience, computer science, mathematics, physics and philosophy. At the same time, the development of imaging devices and popularization of stereoscopic effects has increased student interest in vision. This primer provides an overview of the principles of space perception in a handbook format that should appeal to researchers as well as students. Topics covered include geometrical and distal-proximal relationships, spatial localization, stereopsis, cyclopean perception, stimulus inadequacy, pictorial cues, perceived size and shape, Gibsonian psychophysics, lateral motion, motion in depth, perceived object motion, and motion detection.

Handbook of Visual Optics offers an authoritative overview of encyclopedic knowledge in the field of physiological optics. It builds from fundamental concepts to the science and technology of instruments and practical procedures of vision correction, integrating expert knowledge from physics, medicine, biology, psychology, and engineering. The chapters comprehensively cover all aspects of modern study and practice, from optical principles and optics of the eye and retina to novel ophthalmic tools for imaging and visual testing, devices and techniques for visual correction, and the relationship between ocular optics and visual perception.

The Eye: Volume 2, The Visual Process is a compendium of papers that describes the physiology of the eye, particularly the visual functions, the photobiology of the visual process, and the visual pathway. One paper describes the light stimuli used in physiological experiments concerning vision in terms of their spectral energy distribution, particularly the amounts of light absorbed by the photosensitive substances contained in the retinal receptors. Another paper explains the mosaic-like arrangement of the receptors and the variations of this mosaic in the different regions of the retina, including the Purkinje phenomenon which can cause errors in visual measurements. One paper examines the directional properties of the rods at long wavelengths and the theory of the Stiles-Crawford effect. Other papers investigate the limits of the visible spectrum, the scotopic luminous efficiency, theories of dark-adaptation, as well as the minimum retinal illumination, the minimum flux of energy, and the minimum amount necessary for vision. One paper notes that whereas one rod can be stimulated by one quantum (a discrete process involving one pigment molecule), it is not sufficient to make a human subject see a light stimulus. The compendium is invaluable for researchers and investigators involved in physiology, psychology, ophthalmology, and in all branches of ocular physiology.

The Eye: Volume 1, Vegetative Physiology and Biochemistry is a compendium of papers that describes the physiology of the eye, particularly its gross anatomy and embryology including its intra-ocular fluids, the intra-ocular pressure, the vitreous body, lens, cornea, and sciera. Several papers review the eyeball, the protective apparatus of the eye, the structure of the tissue in relation to the intra-ocular fluids, and the flow of aqueous humor. Several methods can be used to measure the intra-ocular pressure such as the manometric method and the tonometer. Giles (1959) reports that tonometer measurements in the newborn are within the normal adult range. One paper notes that in man, liquefaction of the vitreous body (the clear jelly-like structure which fills the space between retina and lens,) which is caused by dissolution of the fibrous network, is never repaired. This suggests that new fibers are either not formed or are formed in insufficient amounts. Another paper examines the relationship between pressure in the eye vessels and eye tension. Investigators and researches in the fields of physiology, psychology, ophthalmology, and in all branches of ocular physiology will find the compendium very rewarding.

Based on a conference held in honor of Professor Tarow Indow, this volume is organized into three major topics concerning the use of geometry in perception: * space -- referring to attempts to represent the subjective space within which we locate ourselves and perceive objects to reside; * color -- dealing with attempts to represent the structure of color percepts as revealed by various experimental procedures; and * scaling -- focusing on the organization of various bodies of data -- in this case perceptual -- through scaling techniques, primarily multidimensional ones. These topics provide a natural organization of the work in the field, as well as one that corresponds to the major aspects of Indow's contributions. This book's goal is to provide the reader with an overview of the issues in each of the areas, and to present current results from the laboratories of leading researchers in these areas.

The study of the functional organization of the first synapse of the centripetal visual pathway at the outer plexiform layer level (OPL) ought to be made through the application of combined histological, electrophysiological, and neurochemical techniques. A large amount of new evidence has been accumu lated in the past 20 years on the structure of the retina and on the electrical responses of retinal cells to light stimulus. Also, recently, many substances considered as neurotransmitters in the brain have been found in the retina. The goal of the study of retinal function is to integrate the data obtained by structural and electrophysiological techniques and to identify and determine the role played by neurotransmitters or neuromodulators in the function of the retina. In this study it is important to realize the morphological and biochemical diversi ty displayed by the visual cells in the vertebrate retina which, according to Cresci telli (1972), has been produced "through the interaction of natural selection with diversity in the photic environment." The evidence obtained shows that bipolar and especially horizontal cells, closely related to visual cells, display morphologi cal and probably biochemical differences among classes, genus, and even species according to the photic environment. These differences give peculiarities to the organization of the OPL, which must be taken into account when studying a par ticular retina with electrophysiological or neurochemical techniques.

Infant Perception: From Sensation to Cognition, Volume I: Basic Visual Processes focuses on the study and programmatic investigations of infant perception, examining early sensory, perceptual, and cognitive systems. This book is divided into five chapters. Chapter 1 analyzes the major physiological and behavioral techniques used to measure infant vision. Each technique is critically evaluated in terms of the method employed, type of data that can be obtained, and anatomy of the visual system. The neuronal model to explain developmental changes and techniques used to assess infant visual preferences for patterns varying in amount of contour are discussed in Chapter 2. Chapter 3 demonstrates the value of the corneal reflection technique for the study of infant attention and visual scanning patterns, while Chapter 4 examines the developmental changes and individual differences in early pattern perception. The last chapter concentrates on the evidence of infant visual preferences for novelty and on the implications of such evidence for models of early recognition memory. This publication is a good reference for pediatricians and clinicians concerned with infant perception.
