Ocular Rigidity, Biomechanics and Hydrodynamics of the Eye


Book Description

This book focuses on the concept of ocular rigidity, the biomechanical properties and hydrodynamics of the human eye. The basics of anatomy and physiology are explored and the relevant data for the clinician are emphasized throughout the book. The engineering aspects as well as the clinical interpretation are presented to provide context. Ocular Rigidity, Biomechanics and Hydrodynamics of the Eye summarises recent evidence on ocular rigidity, but also provides a complete presentation of the data so far. The authors have recently worked on ocular rigidity corneal and globe biomechanics and hydrodynamics and the new, up-to-date data on the subject are highlighted in each chapter. The aim is to provide the framework or the understanding of these parameters and to determine their relevance in health and disease. This book will be an essential read for all practicing ophthalmologists looking to gain a more in-depth understanding of this interesting area of research particularly in refractive surgery and glaucoma.




Optic Nerve in Glaucoma


Book Description




Introductory Biomechanics


Book Description

Introductory Biomechanics is a new, integrated text written specifically for engineering students. It provides a broad overview of this important branch of the rapidly growing field of bioengineering. A wide selection of topics is presented, ranging from the mechanics of single cells to the dynamics of human movement. No prior biological knowledge is assumed and in each chapter, the relevant anatomy and physiology are first described. The biological system is then analyzed from a mechanical viewpoint by reducing it to its essential elements, using the laws of mechanics and then tying mechanical insights back to biological function. This integrated approach provides students with a deeper understanding of both the mechanics and the biology than from qualitative study alone. The text is supported by a wealth of illustrations, tables and examples, a large selection of suitable problems and hundreds of current references, making it an essential textbook for any biomechanics course.




The Optic Nerve Head in Health and Disease


Book Description

The book provides a detailed description in color format of the optic nerve head changes that occur in glaucoma. It explains the normal and variant anatomy of an optic nerve head and why certain discs are more or less likely to develop glaucomatous changes. This book attempts to explain the anatomical basis of common and not so common signs seen in optic nerve head and retinal nerve fibre layer as captured by a digital fundus imaging system and optical coherence tomography. It also includes optic nerve head conditions mimicking glaucoma. The book is relevant for practicing ophthalmologists, vision science researchers, clinical optometrists, postgraduate residents in ophthalmology, sub-specialty fellows as well as general ophthalmologists, neurologists and neurosurgeons.




Structure-Based Mechanics of Tissues and Organs


Book Description

This book portrays the commonality of tissue micro-structure that dictates physiological function in various organs (microstructure-function relation). Tissue and organ models are used to illustrate physiological functions based on microstructure. Fiber scale properties such as orientation and crimp are described in detail. Structurally-based constitutive models are given throughout the book, not only to avoid ambiguities in material characterization, but also to offer insights into the function, structure, and mechanics of tissue components. A statement of future directions of the field is also given, including how advancements, such as state-of-the-art computational modeling and optical measurements of tissue/cells structures, are taking structure-based modeling to the next level. This book also: Provides a comprehensive view of tissue modeling across multiple systems Broadens readers’ understanding of state-of-the-art computational modeling and optical measurements of tissue/cells structures Describes in detail fiber scale properties such as orientation and crimp




Biomechanics of the Eye


Book Description

Covering all major components of the ocular system, this state-of-the-art text is essential for vision scientists, biomedical engineers, and advanced clinicians with an interest in the role of mechanics in ocular function, disease, therapeutics, and surgery. With every chapter, leading experts strengthen the arguments that biomechanics is an indispensable and rapidly evolving tool for understanding and managing ocular disease.




Intraocular and Intracranial Pressure Gradient in Glaucoma


Book Description

This book focuses on the characteristic of glaucomatous optic neuropathy and its relationship with cerebrospinal fluid (CSF) pressure. It also explores the potential novel methods to manage glaucoma by adjusting CSF pressure. This book covers several interesting topics such as why normal tension glaucoma (NTG) patients still develops into glaucoma without high intraocular pressure (IOP); and whether there are factors other than IOP contributing to the pathogenesis of NTG why the role of IOP in the pathogenesis of POAG becomes vague and controversial. This book contains over 40 chapters, including numerous images from clinical patients and experiments on gross anatomy, pathological tissue, and immunohistochemistry, electronic speculum etc. The ophthalmologists and researchers can also benefit from the clinical cases. We hope this book serves as a clinical guidance with practical significant for the understanding, prevention and diagnosis of glaucoma.




Myopia and Glaucoma


Book Description

This book serves as an introductory reference on clinical aspects of glaucoma and myopia, providing essential guidelines for diagnosis and monitoring of glaucoma progression in patients, especially those with high myopias. Many clinical studies are presented by leading experts in the field in an accessible style, making the content suitable not only for ophthalmologists but also for optometrists and certified orthoptists as well as for students. The relation between myopia and glaucoma has been the subject of many clinical trials and population-based studies. Most of the data has suggested that moderate to high myopia is associated with increased risk of primary open-angle glaucoma, normal tension glaucoma, and ocular hypertension. There are several factors involved in the diagnosis of glaucoma, but it is often difficult to determine the presence of glaucoma in myopic eyes. A myopic eye, especially in cases of moderate to high myopia, tends to have a thin retina and choroid and to appear thinner than normal. Even with new imaging technologies with improved sensitivity and specificity for detecting glaucoma, each technology presents some challenges when assessing myopic eyes. This book furnishes an overview of these diagnostic challenges with reference to the growing prevalence and severity of myopia in various parts of the world, providing many valuable hands-on reports and clinical studies by authoritative authors. This knowledge will help to do away with the vague area between high myopia and glaucoma faced by clinicians.
