Introduction We mark the eighth consecutive year for the World Glaucoma Association Glaucoma Consensus with Consensus VIII. Our topic is the Progression of Glaucoma. Global experts were invited and assembled by our international co-Chairs beginning in January 2011, to participate in the Project Forum E-Room, a unique online opportunity to facilitate discussion of each of the consensus meetings. Participants then were engaged in the discussion of five topical areas to reach consensus on key issues that surround and permeate all aspects of the progression of glaucoma. The results of these thoughtful discussions then were summarized by each of the sections with preliminary consensus statements. The Draft of the Consensus Report, including the preliminary consensus statements, was distributed to the Societies and Partners for review and comments prior to the Consensus Meeting that took place in Paris on Tuesday, June 28, 2011. On this day, relevant stakeholders engaged in a stimulating, educational, and thought-provoking session that highlighted the review and revision of the consensus statements. The Consensus Report then was finalized by Consensus co- Chairs and Editors. Consensus statements were reviewed and finalized by the expert Consensus Panel. Robert N. Weinreb, Editor

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.

Preface Childhood is the topic of the ninth World Glaucoma Association Consensus. There has been only sparse attention to the diagnosis and treatment of childhood glaucoma. Both pediatric ophthalmologists and glaucoma specialists provide care for such children. In some instances, they manage these individuals alone and, in others, the management is shared. For this consensus, the participation of both groups was solicited. The global faculty, consisting of leading authorities on the clinical and scientific aspects of childhood glaucoma, met in Vancouver on July 16, 2013, just prior to the World Glaucoma Congress, to discuss the reports and refine the consensus statements. As with prior meetings, it was a daunting task to seek and obtain consensus on such a complicated and nuanced subject. It is unclear how each of us decides how we practice, and evidence to guide us often is sparse. It is remarkable how few high level studies have been conducted on the management of childhood glaucoma. Hence, this consensus, as with the others, is based not only on the published literature, but also on expert opinion. Although consensus does not replace and is not a surrogate for scientific investigation, it does provide considerable value, especially when the desired evidence is lacking. The goal of this consensus was to provide a foundation for diagnosing and treating childhood glaucoma and how it can be best done in clinical practice. Identification of those areas for which we have little evidence and, therefore, the need for additional research also was a high priority. We hope that this consensus report will serve as a benchmark of our understanding. However, this consensus report, as with each of the others, is intended to be just a beginning. It is expected that it will be revised and improved with the emergence of new evidence. Robert N. Weinreb, Chair

This book focuses on the practical aspects of Optical Coherence Tomography (OCT) in glaucoma diagnostics offering important theoretical information along with many original cases. OCT is a non-invasive imaging technique that acquires high-resolution images of the ocular structures. It enables clinicians to detect glaucoma in the early stages and efficiently monitor the disease. Optical Coherence Tomography in Glaucoma features updated information on technical applications of OCT in glaucoma, reviews recently published literature and provides clinical cases based on Cirrus and Spectralis OCT platforms. In addition, newer techniques like event and trend analyses for progression, macular ganglion cell analysis, and OCT angiography are discussed. This book will serve as a reference for ophthalmologists and optometrists worldwide with a special interest in OCT imaging providing essential guidance on the application of OCT in glaucoma.

Computer vision has been successful in several important applications recently. Vision techniques can now be used to build very good models of buildings from pictures quickly and easily, to overlay operation planning data on a neuros- geon’s view of a patient, and to recognise some of the gestures a user makes to a computer. Object recognition remains a very di cult problem, however. The key questions to understand in recognition seem to be: (1) how objects should be represented and (2) how to manage the line of reasoning that stretches from image data to object identity. An important part of the process of recognition { perhaps, almost all of it { involves assembling bits of image information into helpful groups. There is a wide variety of possible criteria by which these groups could be established { a set of edge points that has a symmetry could be one useful group; others might be a collection of pixels shaded in a particular way, or a set of pixels with coherent colour or texture. Discussing this process of grouping requires a detailed understanding of the relationship between what is seen in the image and what is actually out there in the world.

A comprehensive and user-friendly guide on leveraging OCT for the management of glaucoma Optical coherence tomography (OCT) is a noninvasive diagnostic imaging modality that enables ophthalmologists to visualize different layers of the optic nerve and retinal nerve fiber layer (RNFL) with astounding detail. Today, OCT is an instrumental tool for screening, diagnosing, and tracking the progression of glaucoma in patients. Optical Coherence Tomography in Glaucoma by renowned glaucoma specialist Jullia A. Rosdahl and esteemed contributors is a one-stop, unique resource that summarizes the clinical utility of this imaging technology, from basics to advanced analyses. The book features 14 chapters, starting with introductory chapters that discuss development of OCT and its applications for visualizing the optic nerve and macula. In chapter 5, case studies illustrate OCT imaging of the optic nerve, RNFL, and macula in all stages of glaucoma, from patients at risk to those with mild, moderate, and severe diseases. The next chapters cover the intrinsic relationship between optic nerve structure and function, the use of structure–function maps, and examples of their relationship, followed by a comparison of commonly used devices and a chapter on artifacts. Anterior segment OCT is covered next, followed by chapters covering special considerations in pediatric glaucomas and in patients with high refractive errors. The final chapters cover innovations in OCT on the horizon including OCT angiography, swept-source OCT, and artificial intelligence. Key Highlights Illustrative case examples provide firsthand clinical insights on how OCT can be leveraged to inform glaucoma treatment. In-depth guidance on recognizing and managing artifacts including case examples and key technical steps to help prevent their occurrence. Pearls on the use of OCT for less common patient scenarios such as pediatric glaucomas and high refractive errors. Future OCT directions including angiography, swept-source, and the use of artificial intelligence. This practical resource is essential reading for ophthalmology trainees and ophthalmologists new to using OCT for glaucoma.
