Download or read book Barriers and Fluids of the Eye and Brain written by Malcolm Beverley Segal and published by CRC Press. This book was released on 1992 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the latest findings regarding the control of the fluid environments of the eye and brain. The book is comprised of papers presented at a symposium honoring the 80th birthday of Professor Hugh Davson. The contributors are previous students of Hugh Davson who are now leading authorities in the fields of the eye and brain. The eye is considered from its many interfaces, including the role of prostaglandins, blood flow in diabetes, and the vitreous body. Other topics discussed include the role of carbonic anhydrase, cerebrospinal fluid and its drainage, and the development of the blood/brain barrier to macromolecules. The book also shows how recent findings about homologous molecules refute earlier studies with foreign tracers, and offers a fascinating glimpse into the future with a description of the latest imaging techniques used in neurological diagnosis.

Download or read book The Relationship of Ocular and Cerebrospinal Fluids to the Optic Nerve in Health and Glaucoma written by Emily Mathieu and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The optic nerve is a white matter tract that conveys visual information from the eye to the brain. Inside the eye, the optic nerve head is exposed to ocular fluids, and behind the eye, the nerve is surrounded by cerebrospinal fluid (CSF). Ocular fluid and CSF are similar in composition and function, and are in close proximity at the optic nerve interface. Additionally, both fluids drain into cervical lymph nodes via the lymphatic system. Despite these common features, the relationship between these fluids and the optic nerve is poorly understood. Recent studies point to glymphatic paravascular entry of CSF into brain tissue to deliver nutrients and to clear metabolic waste. The hypothesis of this thesis is that ocular fluid and CSF enter the optic nerve via paravascular pathways and that this is relevant to glaucoma, the leading cause of irreversible blindness worldwide. My investigations reveal that ocular fluid flows into the optic nerve head by diffusion rather than via a paravascular pathway. In contrast, CSF flows into the optic nerve via paravascular spaces bordered by optic nerve capillaries and astrocytic endfeet containing aquaporin water channels. Furthermore, studies revealed size dependent entry of CSF solutes with preferential entry of smaller molecules. Additionally, CSF flowed into the optic nerve only up to the optic nerve head. Finally, in a spontaneous glaucoma model, studies revealed markedly impaired CSF flow into the optic nerve in association with nerve damage. These results are the first to show the intimate relationship of ocular fluid and CSF to the optic nerve. These novel findings will help us to understand the optic nerve in both health and in disease such as glaucoma.

Download or read book Ocular Fluid Dynamics written by Giovanna Guidoboni and published by Springer Nature. This book was released on 2019-11-25 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters in this contributed volume showcase current theoretical approaches in the modeling of ocular fluid dynamics in health and disease. By including chapters written by experts from a variety of fields, this volume will help foster a genuinely collaborative spirit between clinical and research scientists. It vividly illustrates the advantages of clinical and experimental methods, data-driven modeling, and physically-based modeling, while also detailing the limitations of each approach. Blood, aqueous humor, vitreous humor, tear film, and cerebrospinal fluid each have a section dedicated to their anatomy and physiology, pathological conditions, imaging techniques, and mathematical modeling. Because each fluid receives a thorough analysis from experts in their respective fields, this volume stands out among the existing ophthalmology literature. Ocular Fluid Dynamics is ideal for current and future graduate students in applied mathematics and ophthalmology who wish to explore the field by investigating open questions, experimental technologies, and mathematical models. It will also be a valuable resource for researchers in mathematics, engineering, physics, computer science, chemistry, ophthalmology, and more.

Download or read book Spaceflight Associated Neuro-Ocular Syndrome written by Andrew G. Lee and published by Academic Press. This book was released on 2022-07-16 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prolonged microgravity exposure during long-duration spaceflight (LDSF) produces unusual physiologic and pathologic neuro-ophthalmic findings in astronauts. These microgravity-associated findings collectively define the Spaceflight Associated Neuro-ocular Syndrome (SANS). In this book, the editors compare and contrast prior published work on SANS by the National Aeronautics and Space Administration’s (NASA) Space Medicine Operations Division with retrospective and prospective studies from other research groups. The book describes the possible mechanisms and potential etiologies for SANS, and provides an update and review on the clinical manifestations of SANS including: unilateral and bilateral optic disc edema, globe flattening, choroidal and retinal folds, hyperopic refractive error shifts, and focal areas of ischemic retina (i.e., cotton wool spots). The ocular imaging findings (e.g., retinal nerve fiber layer, optic disc, and choroidal changes on optical coherence tomography) of SANS is also described, including the intraorbital and intracranial findings on orbital ultrasound and magnetic resonance imaging. The knowledge gaps for in-flight and terrestrial human research including potential countermeasures for future stud is also explored, including reports on the in-flight and terrestrial human and animal research being investigated by NASA and its partners to study SANS both prospectively and longitudinally and in preparation for future long duration manned missions to space including the moon, the asteroid belt, or Mars. We think this is a unique topic and hope that NASA and its research partners continue to study SANS in preparation for future longer duration manned space missions. Written in an easy-to-read manner, the book adopts a translational approach and explores the science and the clinical manifestations of Space flight associated neuro-ocular syndrome. It is also multi-disciplinary and suitable for both clinicians and researchers in ophthalmology, neurology, and aerospace medicine interested in SANS SANS is a unique space flight disorder that has no terrestrial equivalent. The book involves contributions from international experts across multiple disciplines to tackle the problem of SANS Summarizes and reviews the current findings of SANS, including possible mechanisms and potential etiologies, clinical manifestations, current reports on the in-flight and terrestrial human and animal research, and ocular imaging findings

Download or read book Implications of the Blood-Brain Barrier and Its Manipulation written by E.A. Neuwelt and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the structure and function of the blood-brain barrier (BBB) and recogniz ing its clinical relevance require a concert of scientific disciplines applied from a view point of integrative physiology rather than from only molecular or analytical approaches. It is this broad scope that is emphasized in this book. In my opinion, four original contributions define the field as it exists today. The first, a monograph by Broman,1 entitled The Permeability of the Cerebrospinal Vessels in Normal and Pathological Conditions, was the model for many subsequent clinical and 3 experimental studies on BBB pathology. Second, experiments by Davson, summarized in his book entitled Physiology of the Ocular and Cerebrospinal Fluids, indicated that passive entry of nonelectrolytes into brain from blood is governed largely by their lipid 4 solubility. This research supported the original suggestion by Gesell and Hertzman that cerebral membranes have the semipermeability properties of cell membranes. The modem era of the barrier was introduced with the 1965 paper by Crone,2 entitled "Facilitated transfer of glucose from blood to brain tissue. " This paper identified stereospecific, facilitated transport of glucose as part of a system of regulatory barrier properties at a time when only a barrier to passive diffusion had been contemplated. Finally, the 1967 paper by Reese and Kamovsky, 11 entitled "Fine structural localization of a blood-brain barrier to exogenous peroxidase," sited the barrier at the continuous layer of cerebrovascular endothelial cells, which are connected by tight junctions.
