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.
This book is designed to be concise with a consistent format so that the clinician can focus on a specific area. This edition has had major modifications and embraces evidence-based medicine.

Incorporates evidence-based medicine so you feel confident that you're formulating the best treatment plans for your patients.Color photos allow you to read about and actually see a picture of select disease entities.Clear, concise format can be photocopied and distributed to patients in some cases, reducing your time spent explaining problems to patients and caregivers.
Glaucoma affects all age groups and is a leading cause of blindness worldwide. It is imperative that practicing clinicians and surgeons recognize both primary and secondary glaucoma as well as cases of glaucoma associated with other disorders. Atlas of Glaucoma, Third Edition provides an in-depth review and analysis of the management of glaucoma and discusses research advancements that have resulted in the latest therapies. See What's New in the Third Edition: The influence of the cornea on intraocular pressure measurements and new devices designed to account for this Spectral domain optical coherence tomography (OCT) New statistical methods for tracking rates of progression New medications released since 2006 New chapter on trabecular bypass surgery Additional topics include: Classification of glaucoma Measurement of intraocular pressure and gonioscopy The optic nerve Psychophysical and electrophysiological testing in glaucoma Primary open-angle, secondary open-angle, and angle closure glaucomas Ocular blood flow and metabolism Medical therapy and surgical treatments Aqueous shunts Combined cataract and glaucoma surgery Treatment of developmental glaucoma This colorful atlas contains detailed captions for each illustration, making it ideal for teaching purposes as well as a reference for the practicing ophthalmologist. Glaucoma encompasses a wide variety of clinical entities, clinical findings, diagnostic techniques, and treatment options. This book presents a vast assemblage of insight from internationally recognized experts.
Recent Advances in Ophthalmology focuses on developments in ophthalmology, including therapy, keratotomy, phototoxicity, and retinopathy. The compilation first offers information on the therapy of herpes simplex, anterior segment surgery, and use of viscous and viscoelastic substances in ophthalmology. Topics include systemic antiviral agents and ocular disease; influence of new instruments and technology; criteria for the selection of viscous or viscoelastic material; and indications for the use of viscous substances. The text then ponders on radial keratotomy, intraocular lenses, and treatment of congenital cataracts. The publication takes a look at ocular phototoxicity and vitreous surgery, as well as proliferative diabetic retinopathy, posterior penetrating trauma, effects of non-ionizing radiation on biological systems, body temperature and light damage, and retinal photodamage. The text also touches on the management of diabetic retinopathy; treatment of malignant melanomas of the posterior uvea; and macular disease with serious retinal detachment. The compilation is highly recommended for ophthalmologists and readers interested in the developments in ophthalmology.
This book illustrates effective surgical techniques for treating glaucoma in a practical and easy to follow format. Within the various chapters the different steps for all surgical procedures are clearly described to guide the reader through each clinical presentation. There are many drawings with detailed explanations regarding incisional surgical techniques such as trabeculectomy, shunts and non perforating techniques, canaloplasty and modern Microinvasive Glaucoma Surgeries (MIGSs). Surgical anatomy, different anesthetic techniques, medical therapy, laser treatments and choice of treatment to contrast glaucoma are also explained throughout the book. Finally there are three chapters on the most modern and effective surgical procedures, drawn up by leading internationally renowned ophthalmologists. This book will be an essential clinical resource for a wide range of readers including ophthalmologists in training, experienced surgeons and glaucoma specialists.
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.
