This book was released on 2009-03-31 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been suspected since more than a century that disturbed ocular blood flow (OBF) may play a role in the pathogenesis of glaucoma. Reduced OBF has been measured in glaucoma patients by numberless centres with different techniques in different tissues of the eye. And reduced OBF has been proven to be of prognostic value. Nevertheless the implementation of this knowledge into clinical practice has been very slow. This practical book will help many ophthalmologists to better understand glaucoma. The reading of this book will not only improve patient care but also give the reader intellectual satisfaction.

Available in PDF, EPUB and Kindle. Book excerpt: Preface Open angle glaucoma (OAG) is one of the leading causes of impaired vision worldwide. The pathogenesis of glaucomatous optic neuropathy remains poorly understood, and several pathogenic mechanisms are proposed to coexist. As the world population ages, OAG will become more prevalent and advances in the diagnosis and treatment of glaucomatous optic neuropathy are important to protect and improve the quality of life of our aging population. Treatment of OAG has been directed at lowering intraocular pressure (IOP) which is the only current therapeutic strategy available to patients with glaucoma. While a wide variety of studies have demonstrated that lowering IOP decreases the risk of glaucoma development and/or progression, many studies have also shown that some patients continue to lose vision despite significant lowering of IOP. There have been many attempts to elucidate the etiology for the deterioration in glaucomatous optic neuropathy despite low levels of IOP. Over the past several decades, deficits in the ocular circulation of patients with OAG have become well established and these may explain the continued progression of OAG patients despite lowered IOP. The purpose of the present publication is to provide an updated view of ocular blood flow and vascular dysregulation in OAG. The importance of the topic was demonstrated by the focus of the 2009 6th Consensus meeting of the World Glaucoma Association which focused entirely on blood flow deficits in patients with OAG. Although a great deal of knowledge on vascular risk factors in glaucoma has already been established, many questions remain. Do ocular blood flow deficits precede glaucoma progression? How does ocular perfusion pressure fit into the IOP and blood flow paradigm? What conclusions can be drawn from recent evidence showing the fluctuation of OAG risk factors including IOP, blood pressure and ocular perfusion pressure? We hope this update d current prospective will serve as a foundation for future investigations which will be designed to answer these and other important considerations in the management of glaucoma.

Download or read book Marijuana As Medicine written by Institute of Medicine and published by National Academies Press. This book was released on 2000-12-30 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some people suffer from chronic, debilitating disorders for which no conventional treatment brings relief. Can marijuana ease their symptoms? Would it be breaking the law to turn to marijuana as a medication? There are few sources of objective, scientifically sound advice for people in this situation. Most books about marijuana and medicine attempt to promote the views of advocates or opponents. To fill the gap between these extremes, authors Alison Mack and Janet Joy have extracted critical findings from a recent Institute of Medicine study on this important issue, interpreting them for a general audience. Marijuana As Medicine? provides patientsâ€"as well as the people who care for themâ€"with a foundation for making decisions about their own health care. This empowering volume examines several key points, including: Whether marijuana can relieve a variety of symptoms, including pain, muscle spasticity, nausea, and appetite loss. The dangers of smoking marijuana, as well as the effects of its active chemical components on the immune system and on psychological health. The potential use of marijuana-based medications on symptoms of AIDS, cancer, multiple sclerosis, and several other specific disorders, in comparison with existing treatments. Marijuana As Medicine? introduces readers to the active compounds in marijuana. These include the principal ingredient in Marinol, a legal medication. The authors also discuss the prospects for developing other drugs derived from marijuana's active ingredients. In addition to providing an up-to-date review of the science behind the medical marijuana debate, Mack and Joy also answer common questions about the legal status of marijuana, explaining the conflict between state and federal law regarding its medical use. Intended primarily as an aid to patients and caregivers, this book objectively presents critical information so that it can be used to make responsible health care decisions. Marijuana As Medicine? will also be a valuable resource for policymakers, health care providers, patient counselors, medical faculty and studentsâ€"in short, anyone who wants to learn more about this important issue.

Book excerpt: This atlas offers a truly comprehensive update on the use of imaging technologies for the diagnosis and follow-up of glaucoma. In addition to standard automated perimetry, gonioscopy, fundus photography, and stereophotography, other advanced, high-resolution methods for imaging the eye in glaucoma are explained in detail, including ultrasound biomicroscopy, confocal scanning laser ophthalmoscopy, scanning laser polarimetry, and spectral domain optical coherence tomography. The role of the various tests and the keys to optimizing their use in clinical practice are detailed with the aid of high-quality figures in order to enable the reader to achieve the best possible performance when applying these tools. The risk of developing visual disability and blindness as a consequence of glaucoma varies widely among affected individuals. Personalized testing strategies and tailored therapeutic interventions are required to effectively reduce visual impairment due to glaucoma. Glaucoma Imaging will assist residents, researchers, and clinicians in improving their ability to understand and integrate the information obtained using traditional techniques with the reports provided by computer-assisted image instruments.
Download or read book The Ocular Circulation written by Jeffrey W. Kiel and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes the unique anatomy and physiology of the vascular beds that serve the eye. The needs for an unobstructed light path from the cornea to the retina and a relatively fixed corneal curvature and distance between refractive structures pose significant challenges for the vasculature to provide nutrients and remove metabolic waste. To meet these needs, the ocular vascular beds are confined to the periphery of the posterior two thirds of the eye and a surrogate circulation provides a continuous flow of aqueous humor to nourish the avascular cornea, lens and vitreous compartment. The production of aqueous humor (and its ease of egress from the eye) also generates the intraocular pressure (IOP), which maintains the shape of the eye. However, the IOP also exerts a compressing force on the ocular blood vessels that is higher than elsewhere in the body. This is particularly true for the intraocular veins, which must have a pressure higher than IOP to remain patent, and so the IOP is the effective venous pressure for the intraocular vascular beds. Consequently, the ocular circulation operates at a lower perfusion pressure gradient than elsewhere in the body and is more at risk for ischemic damage when faced with low arterial pressure, particularly if IOP is elevated. This risk and the specialized tissues of the eye give rise to the fascinating physiology of the ocular circulations.
