Book Description
The long-awaited second edition of an authoritative reference on electrophysiologic vision testing, including detailed information on techniques and problems, basic physiology and anatomy, theoretical concepts, and clinical findings; with extensive new material. This authoritative text is the only comprehensive reference available on electrophysiologic vision testing, offering both practical information on techniques and problems as well as basic physiology and anatomy, theoretical concepts, and clinical correlations. The second edition, of the widely used text, offers extensive new material and updated information: 65 of the 84 chapters are completely new, with the changes reflecting recent advances in the field. The book will continue to be an essential resource for practitioners and scholars from a range of disciplines within vision science. The contributions not only cover new information—important material that is likely to become more important in the next decade—but also offer a long-range perspective on the field and its remarkable development in the last century. After discussing the history and background of clinical electrophysiology, the book introduces the anatomy of the retina and principles of cell biology in the visual pathways at the molecular, physiological, and biochemical levels. It relates these new findings to the techniques and interpretations of clinical tests, including the electro-oculogram (EOG), electroretinogram (ERG), and visual evoked potentials (VEP), which are discussed in detail, as are equipment, data acquisition and analysis, principles and protocols for clinical testing, diseases and dysfunction, and animal testing. Notable additions for this edition include chapters on the origin of electroretinogram waveforms, multifocal techniques, testing in standard laboratory animals, recent advances in analysis of abnormalities in disease, and the applications of these techniques to the study of genetic abnormalities.

Book Description
Handbook of Basic and Clinical Ocular Pharmacology and Therapeutics provides a review of the basic anatomy, physiology, biochemistry and pathology of the eye with a focus drug therapy, drug delivery and use of therapeutic medical miniature devices. An understanding of the pharmacological actions of drugs acting on the eye requires the student and health care practitioner to learn additional principles in basic and clinical sciences that are unique to this organ. As a sensory organ, the eye is relatively inaccessible to the systemic circulation due to the blood-vitreous, blood-aqueous and blood-retinal barriers. Consequently, the administration of drugs for therapeutic effects in the eye necessitates an understanding of physico-chemical properties of the molecules and pharmacokinetic principles involved in the access to its site of action via topical, intracameral and intravitreal administration. This book includes information on the general principles of pharmacokinetics and pharmacodynamics of drugs as it pertains to the eye and in combating ocular disorders and diseases. Using a disease-themed approach, the book discusses basic and clinical pharmacological principles involved in the therapy of these diseases including the ocular side effect of systemically-administered drugs, drugs used in ophthalmic surgery and miscellaneous agents, the therapeutic utility of biologics, drug conjugates, combination products, gene and cellular therapy are also covered. Handbook of Basic and Clinical Ocular Pharmacology and Therapeutics is useful as a primary and secondary source of reference for up-to-date information about the pharmacological mechanisms of action, pharmacokinetics, side effects, drug-drug interactions and therapeutic indications of drugs for pharmacologists, pharmaceutical scientists, students in the health care disciplines (nursing, pharmacy, optometry, medical), and practitioners in optometry and ophthalmology. - Explains the mechanisms of action, side-effects and therapeutic uses of drugs, biologics, miniature devices, gene and cellular therapies for the eye - Provides a comprehensive review of the anatomy, physiology, biochemistry, pharmacology, microbiology, genetics and pathology of parts of the eye involved in drug therapy to combat eye disorders and diseases - Explores the pharmacological and clinical basis of drugs, drug conjugates, combination products used in the treatment of anterior and posterior segment diseases

Book Description
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, and the retino-occipital or retino-cortical route, which allows slower but refined analysis of the visual scene through the parvocellular pathway. 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 retino-pretectal pathway projecting onto the pretectum is critical for the pupillary or photomotor reflex. The retino-hypothalamic pathway projecting onto the suprachiasmatic nucleus regulates numerous behavioral and biological functions as well as circadian rhythms. The accessory optic system targeting terminal lateral, medial and dorsal nuclei through the paraoptic fasciculus plays a role in head and gaze orientation as well as slow movements. Taken together, these neurovisual systems involve 60% of brain activity, thus highlighting the importance of vision in the functioning and regulation of the central nervous system. But vision is first and foremost action, which makes perception impossible without movement. Binocular coordination is a prerequisite for binocular fusion of the object of interest on the two foveas, thus ensuring visual perception. The retino-collicular pathway is sufficient to elicit reflexive eye movements with short latencies. Thanks to its motor neurons, the superior colliculus activates premotor neurons, which themselves activate motor neurons of the oculomotor, trochlear and abducens nuclei. At a higher level, a cascade of neural mechanisms participates in the control of decisional eye movements. The superior colliculus is controlled by the substancia nigra pars reticulata, which is itself gated by subcortical structures such as the dorsal striatum. The superior colliculus is also inhibited by the dorsolateral prefrontal cortex through a direct prefrontotectal tract. Cortical areas are crucial for the triggering of eye movements: the frontal eye field, supplementary eye field, and parietal eye field. Finally the cerebellum maintains accuracy. The focus of the present research topic, entitled Neural bases of binocular vision and coordination and their implications in visual training programs, 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 is put on studies that enable transfer of knowledge toward visual training programs targeting visual field defects (e.g., hemianopia) and binocular functional disorders (e.g., amblyopia).
