Book Description
The visual field refers to the total area in which objects can be seen in the side (peripheral) vision when the eyes are focused on a central point. Glaucoma is a condition of the eye in which the optic nerve is damaged due to increased fluid pressure in the eye. If untreated or uncontrolled, glaucoma first causes peripheral vision loss and eventually can lead to blindness. A visual field test is a method of measuring an individual's entire scope of vision, that is their central and peripheral (side) vision. The test is most frequently used to help detect glaucoma but may also be used for detection of central or peripheral diseases of the retina, eyelid conditions such as drooping (ptosis), optic nerve damage and disease, and conditions affecting the visual pathways from the optic nerve to the area of the brain (occipital cortex) where this information is processed into vision. The fourth edition of this comprehensive text provides ophthalmologists and trainees with a guide to the interpretation of visual field tests and subsequent diagnosis and management of ocular disorders. The book has been fully revised and features additional topics including two new classification systems for glaucoma. Nearly 800 clinical photographs and diagrams further enhance learning. Key points Comprehensive guide to interpretation of visual field tests and diagnosis of ocular disorders Fully revised fourth edition featuring many new topics Features nearly 800 clinical photographs and diagrams Previous edition (9788184488661) published in 2008

Book Description
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.

Book Description
Written at an introductory level, and featuring engaging case examples, this book reviews the theory and practice of personal and egocentric network research. This approach offers powerful tools for capturing the impact of overlapping, changing social relationships and contexts on individuals' attitudes and behavior. The authors provide solid guidance on the formulation of research questions; research design; data collection, including decisions about survey modes and sampling frames; the measurement of network composition and structure, including the use of name generators; and statistical modeling, from basic regression techniques to more advanced multilevel and dynamic models. Ethical issues in personal network research are addressed. User-friendly features include boxes on major published studies, end-of-chapter suggestions for further reading, and an appendix describing the main software programs used in the field.

Book Description
Presents an emerging model in which occupational therapists practice as part of a team of vision rehabilitation professionals serving adults with low vision. Occupational therapists offer a unique contribution to the vision rehabilitation team, with a focus on meaningful occupational goals, the incorporation of occupation into therapy, and the orchestration of environmental, social, and non-visual personal factors into a treatment plan. The authors have developed a practical and straightforward text outlining an evaluation approach to interventions that focus on recovering occupational performance in adults.

Book Description
Today many companies are employing a user-centered design (UCD) process, but for most companies, usability begins and ends with the usability test. Although usability testing is a critical part of an effective user-centered life cycle, it is only one component of the UCD process. This book is focused on the requirements gathering stage, which often receives less attention than usability testing, but is equally as important. Understanding user requirements is critical to the development of a successful product. Understanding Your Users is an easy to read, easy to implement, how-to guide on usability in the real world. It focuses on the "user requirements gathering" stage of product development and it provides a variety of techniques, many of which may be new to usability professionals. For each technique, readers will learn how to prepare for and conduct the activity, as well as analyze and present the data —all in a practical and hands-on way. In addition, each method presented provides different information about the user and their requirements (e.g., functional requirements, information architecture, task flows). The techniques can be used together to form a complete picture of the users' requirements or they can be used separately to address specific product questions. These techniques have helped product teams understand the value of user requirements gathering by providing insight into how users work and what they need to be successful at their tasks. Case studies from industry-leading companies demonstrate each method in action. In addition, readers are provided with the foundation to conduct any usability activity (e.g., getting buy-in from management, legal and ethical considerations, setting up your facilities, recruiting, moderating activities) and to ensure the incorporation of the results into their products.·Covers all of the significant requirements gathering methods in a readable, practical way·Presents the foundation readers need to prepare for any requirements gathering activity and ensure that the results are incorporated into their products ·Includes invaluable worksheet and template appendices·Includes a case study for each method from industry leaders·Written by experienced authors who teach conference courses on this subject to usability professionals and new product designers alike
