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.

Maximum oxygen uptake during exercise is one of the best predictors of operative mortality and of prognosis in chronic cardiac or respiratory disease. Cardio-pulmonary exercise (CPEX) tests are therefore an increasingly common component of pre-operative assessment and the management of patients with chronic cardiopulmonary problems. Part of the Oxford Respiratory Medicine Library (ORML) series, this pocketbook guides clinicians through the parameters measured in CPEX testing so that they can understand the underlying physiology and are able to interpret the results. Clinical scenarios, common patterns, key points, and practical tips all make this book easy to follow, even for those readers who have little prior knowledge of the subject.

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.

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.

When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.

A comprehensive survey on the use of bedside skills and perimetric devices to the test visual fields, and how to interpret the results. To develop the clinician's interpretative skills, the authors include a chapter on visual anatomy and an atlas of 100 real-life cases arranged in anatomic order from retina to striate cortex. By placing a brief clinical vignette with a visual field on one side of the page and a description of the field and its causal lesion on the opposite side, the reader will be able to learn interpretation in a simulated clinical setting. An additional quiz section of twenty randomly arranged visual fields provides readers with an opportunity to test their newly acquired skills.
