Book excerpt: "Binocular vision" literally means vision with two eyes, and refers to the special attributes of vision with both eyes open, rather than one eye only. Our perception under binocular conditions represents a highly complex co-ordination of motor and sensory processes and is markedly different from and more sophisticated than vision with one eye alone. This book reviews our ability to use both eyes, while also providing basic information on the development of binocular vision and on the clinical disorders that interfere with our depth perception, such as strabismus and amblyopia. This book also describes the development of eye movement control, particularly those that are important for reading. In addition, the authors of this book review the phenomenon of ocular dominance (OD) in the light of the types of test used to identify it; question whether inter-test agreement of OD in an individual might be anticipated, and address some practical implications of OD as demonstrated in healthy eyes and in cases where there is compromised binocular function. Other chapters in this book disclose new methodologies in congenital nystagmus eye movements analysis and evaluate heterophoria as an important element of assessment of binocular vision disorders.

Download or read book Neurovision Neural bases of binocular vision and coordination and their implications in visual training programs written by Olivier A. Coubard and published by Frontiers Media SA. This book was released on 2015-10-12 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).
Download or read book The Theory of Binocular Vision written by Ewald Hering and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Theory of Binocular Vision is a book about neurological control theory. In this sense it was far ahead of its time, for the formal development of control theory was many decades in the future when this book appeared in 1868. Hering's principal concept is that the control of eye movements is greatly simplified if there is only one neurological control system commanding the 'double-eye' as a single organ. This idea leads directly to the first thorough exposition of what is now known as Hering's law, that the corresponding muscles of the two eyes are always equally innervated. As Hering eloquently states it, "one and the same impulse of will directs both eyes simultaneously as one can direct a pair of horses with single reins" (Ch. 2). The 19th Century The book was written during an exciting era for physiological research. Before the mid-19th century the study of physiology had been limited to isolated efforts by great men who worked largely without colleagues or organized laboratories. Now for the first time of inquiry, with many sensory physiology was becoming a living field groups working simultaneously on fundamental problems. Like the classical Greeks before them in philosophy, the physiologists of the 19th century were defining in a burst of creative energy the problems 1 2 Introduction which would shape subsequent inquiry; and like the Greeks, they produced a splendid period of science.

Download or read book Normal Binocular Vision written by David Stidwill and published by John Wiley & Sons. This book was released on 2017-09-22 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Binocular vision, i.e. where both eyes are used together, is a fundamental component of human sight. It also aids hand-eye co-ordination, and the perception of the self within the environment. Clinical anomalies pose a wide range of problems to the sufferer, but normal binocular operation must first be understood before the eye specialist can assess and treat dysfunctions. This is a major new textbook for students of optometry, orthoptics and ophthalmology, and also of psychology. Chapters span such key topics as binocular summation, fusion, the normal horopter, anatomy of the extra-ocular muscles, oculomotor control, binocular integration and depth perception. Fully illustrated throughout, the book includes self-assessment exercises at the end of each chapter, and sample experiments in binocular vision functioning.

Download or read book Binocular Vision Disorder written by Denise Drace-Brownell and published by Eliva Press. This book was released on 2021-03-08 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Denise Drace-Brownell identified this unmet need of over 12% of the population in developed countries, with some studies showing a prevalence greater than 30%. These numbers can be expected to increase from society's expanded use of digital devices. She did breakthrough work in technology with the likes of John Bardeen, the only scientist to win two Nobel Prizes in physics. But because of this underdiagnosed vision problem, her fatigue was so great she had to leave her pioneering work behind. Decades later she obtained the diagnosis of her condition, invented technology to resolve her challenges, and wrote this patient guide which contains new and valuable information to help patients find their own resolution. This paper discusses common symptoms of binocular vision disorder, available resources, and typical therapeutic approaches. Binocular vision disorder impacts corporate productivity, life choices, and ability to make a living. Annual economic damage assessments in the US alone are conservatively estimated at $236.5 billion. Special considerations concern an individual's limitations in working with formulas, such as those in equations, chemical compositions, spreadsheets, and algorithms. The visual process of reading a formula is different from reading a word. Enhanced visual skills are needed, which are not elaborated upon in this paper. The transformation to a digital age demands a transformation in vision diagnostics, treatments, and technologies. About the Author: During her career as a science and technology innovation executive, Denise Drace-Brownell has created successful businesses and furthered breakthrough ideas for emerging growth and Fortune 500 companies. Denise is an expert in vision capabilities required for next-generation digital economies. Denise holds a Bachelor of Science degree from the University of Illinois; a Master's in Public Health/Engineering from Columbia University Medical Center's Mailman School of Public Health; and a law degree from Rutgers, with advanced work at the University of Pennsylvania. She is a certified optician. Denise is a published author and has delivered speeches and papers at several institutions and forums including the Polytechnic Institute of New York University, the Bentley Global Business Ethics Symposium sponsored by State Street Bank and Bentley College, Licensing Executives Society International, Inc., and the Association for Corporate Growth.

Available in PDF, EPUB and Kindle. Book excerpt: Who would have thought that a basic eye alignment problem could cause a person to be miserable or disabled? Yet that is exactly what is happening with Vertical Heterophoria (VH), a visual condition where there is a slight vertical image misalignment which causes headaches, dizziness, anxiety, neck pain and reading difficulties. Using techniques developed by Dr. Debby Feinberg, patients are fit with prism eyeglass lenses that realign the images, resulting (on average) in an 80% reduction of symptoms. This book contains the stories of those suffering from VH, their difficult journey through life and the medical system, and their recovery and return to health using just a simple pair of properly prescribed prism lenses."Who, indeed, could have supposed that a mere ocular defect could have given rise to so serious a train of evils...and who that had not seen it, could believe that the correction by glasses of the eye trouble could have given a relief so speedy and so perfect that the patient described it as a miracle?"
