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.

This book covers interpretation of visual fields by Humphrey and Octopus perimeters and discussion of Humphrey visual fields in a variety of ocular disorders.It examines dilemmas faced by an ophthalmologist while evaluating visual fields which do not match with the clinical picture. Glaucoma, the commonest condition for visual field investigation is discussed in detail. Logical reasoningfor incorporating perimetry in glaucoma management with a clear understanding of the challenges in its interpretation is delved into. The book progresses to advanced glaucoma and glaucoma progression. It discusses a systematic evaluation of various parts of the visual field so that the reader can make a calculated management plan for their patient. Each chapter attempts to clearly enunciate factors that help in the diagnosis and features which may be confused with other conditions. Fields which help diagnosing early, advanced glaucoma and glaucoma progression with images and methods of ensuring reasonable diagnostic accuracy are included. The book incorporates separate chapters on ocular conditions which also mimic visual field defects of glaucoma with detailed modes of correct diagnosis, diagnostic dilemmas arising from retinal, macular, vascular, visual pathway lesions mimicking visual field defects of glaucoma or while coexisting with glaucoma, supported by algorithms to achieve a quick diagnosis in a busy OPD without missing the clinical findings and by using minimal investigative modalities. This book helps clinicians to prevent over diagnosis or under diagnosis of glaucoma and helps diagnose cases with morbidities causing visual field defects.

This atlas is a pictorial guide to the interpretation of automated vision fields. It presents more than 300 vision fields from actual patients that illustrate key points in analyzing visual fields. Each field is accompanied by a brief clinical history, interpretation, and explanation. By looking at the fields and reading the text, the reader should develop a systematic approach to analyzing automated fields and should develop pattern recognition for most fields encountered in clinical practice.

This book discusses more than one hundred patients in which visual pathway is involved, and focuses on the role of visual field examination in the diagnosis of these diseases. It also highlights the application of concepts from the new interdiscipline, integration medicine as well as molecular biology and genetics in the analysis of the diseases. In this book, the commonly (typically) noticed changes in the visual field of patients with visual pathway disorders are mainly described in the chapter one titled as “Visual Field-related Anatomy of Visual Pathway” and chapter two titled as “Interpretation of Visual Field Test”, while the majority of the cases presented with "atypical" changes in visual field. At this point, the changes in the visual field could function as either a key to understand the disease, or a question mark which confuses the diagnosis. However, the process of pushing aside a fog around the diagnosis step by step helps the readers to gradually disclose the essence of the disease.

Visual Fields: Examination and Interpretation, 3rd edition contains revisions and updates of earlier material as well as a discussion of newer techniques for assessing visual field disorders. The book begins with a short history of the field of perimetry and goes on to present basic clinical aspects of examination and diagnosis of visual field defects in the optic nerve, optic disc, chorioretina, optic chiasm, optic tract, lateral geniculate field bodies, and the calcarine complex. Additional aspects of visual field examination are explored including those of monocular, binocular, and junctional field defects, congruity vs. incongruity, macular sparing vs. macular splitting, density, wedge-shaped homonymous field loss, and monocular temporal crescent. Various new techniques of automated perimetry are also considered including SITA, FASTPAC, and SWAP. This volume provides a very useful overview of the techniques of visual field examination in a number of eye disorders and will be of interest to all ophthalmologists, neuro-opthalmologists, retina specialists, and optometrists.
