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.

The nature, control, and disorders of eye movements are topics which draw together scientists from many diverse fields. On October 29-30, 1976, a Symposium on Eye Movements was held at The University of Texas Health Science Center at San Antonio. The Symposium constituted the Southern Sectional Meeting of the Association for Research in Vision and Ophthalmology. The Program Coordinators, Drs. Frank Bajandas and Barbara Brooks invited an outstanding group of participants to give presentations on a variety of aspects of this subject. This volume contains all of the invited presentations delivered at that meeting. It does not include the excellent free papers, nor the enthusiastic and fruitful discussions that the participants and the audience enjoyed as well. The editorial work for this book was performed by Dr. Brooks and Dr. Bajandas with great care and efficiency. They have made special efforts together with the Publisher, Plenum Press, to bring this information to you in the shortest possible time, so as to retain the currency of its contents. This effort would not have been even considered without the tireless and always dependable assistance of Mrs. Catherine Arocha and Mrs. Louise Whelan. We are also indebted to the ~exas State Commission for the Blind for its help in defraying the expenses ever attendant at significant symposia. George W. Weinstein, M.D.

Among the many intense light sources, excimer lasers have a unique set of properties that place them at the forefront of tooling for material processing. Their extreme versatility means that they can be used in many areas of materials science and medicine. But three conditions need to be fulfilled in order that their versatility be truly appreciated and exploited: the characteristics and limitations of the sources must be known; the basic excimer laser processes should become reasonably widely known; and problems in search of a solution should be clearly identified. Excimer Lasers covers all three of these points in an instructive and logical way. Probably for the first time, both instrumental and fundamental aspects of excimer laser interaction with matter are presented side-by-side, with examples drawn from the widest range of materials. The articles gathered here are tutorial in their nature, thus making them suitable for a wide readership, from recent graduates and postgraduate students to those established scientists entering the field, all of whom could not find a better, nor more authoritative work with which to start their reading.

Some of the best vision scientists in the world in their respective fields have contributed to chapters in this book. They have expertise in a wide variety of fields, including bioengineering, basic and clinical visual science, medicine, neurophysiology, optometry, and psychology. Their combined efforts have resulted in a high quality book that covers modeling and quantitative analysis of optical, neurosensory, oculomotor, perceptual and clinical systems. It includes only those techniques and models that have such fundamentally strong physiological, control system, and perceptual bases that they will serve as foundations for models and analysis techniques in the future. The book is aimed first towards seniors and beginning graduate students in biomedical engineering, neurophysiology, optometry, and psychology, who will gain a broad understanding of quantitative analysis of the visual system. In addition, it has sufficient depth in each area to be useful as an updated reference and tutorial for graduate and post-doctoral students, as well as general vision scientists.

This outstanding volume in the Essentials in Ophthalmology series presents recent developments in the diagnosis and treatment of corneal disease. Its intention is not to replace the relevant textbooks, but to serve as a bridge between primary and tertiary literature. The superbly structured volume covers a dizzying array of topics including Herpes simplex keratitis; amniotic membrane transplantation for the treatment of corneal ulceration in infectious keratitis; and Chlamydial infection, all three of which are hugely relevant today. All the topics have direct clinical importance and will not only keep ophthalmologists up to date, but will inform them of how to treat their cornea patients with optimal diagnostic and therapeutic procedures.

For more than 30 years, the visual cortex has been the source of new theories and ideas about how the brain processes information. The visual cortex is easily accessible through a variety of recording and imagining techniques and allows mapping of high level behavior relatively directly to neural mechanisms. Understanding the computations in the visual cortex is therefore an important step toward a general theory of computational brain theory.

Aimed at students taking a course on visual perception, this textbook considers what it means for a man, a monkey and a computer to perceive the world. After an introduction and a discussion of methods, the book deals with how the environment produces a physical effect, how the resulting "image" is processed by the brain or by computer algorithms in order to produce a perception of "something out there." It also discusses color, form, motion, distance, and also the sensing of three dimensionality, before dealing with visual perception and its role in awareness and consciousness. The book concludes with discussions of perceptual development, blindness, and visual disorders. Visual perception is by its very nature an interdisciplinary subject that requires a basic understanding of a range of topics from diverse fields, and this is a very readable guide to all students whether they come from a neuroscience, psychology, cognitive science, robotics, or philosophy background.

The value of Age-Related Macular Degeneration has stood the test of time, but progress in both basic and clinical ophthalmology has been relentless, mandating the need for an updated book. This second edition focuses on the pathophysiology and the epidemiology of age-related macular degeneration (AMD), the clinical features and management of dry and wet AMD, imaging techniques, and medical therapy for both non-neovascular AMD and neovascular AMD. It describes both clinically validated and experimental therapies as well as rehabilitation technology, and presents strategies to prevent the progression of non-exudative AMD. Results from current clinical trials are also included. New chapters in this edition cover: Genetics and treatment Oxidative stress and its relation to the pathophysiology of AMD and CNV (choroidal neovascularization-a common symptom of wet AMD) Polypoidal choroidal vasculopathy Microperimetry and psychophysical testing and ways to track geographic atrophy progression Non-VEGF pathways Retinal stem cells

Ophthalmic microsurgery is applied in ophthalmic pathological conditions. Ophthalmic pathology sets the landmarks for all kinds of microsurgical manipulations. Thus, in order to ensure the best surgical outcome, ophthalmic clinicians and microsurgeons have to consider the critical structures and potential complications before they start with the surgical procedure.

Written by the world famous expert G. O. H. Naumann, this excellent textbook emphasizes the ocular structures such as the nuances of morphology, surgical anatomy, and pathology.

The content includes: Unique features of closed system intraocular surgery in closed system and open eye surgery.- Crucial aspects of restoring the anterior chamber, includes such as the role of blood-ocular barriers and effects of paracenthesis-effects. The spectrum of potential complications in (pseudo-) exfoliation- syndromes as well as the most vulnerable cell populations.- The features of normal and pathologic wound healing in the various tissues after non-mechanical laser and mechanical interventions emergency-pathology requiring prompt surgical intervention.

Brilliant artwork and sketches are further illustrating and summarizing the complex pathology. Thus, the reader will derive great value for the daily routine when learning how the specific pathology modifies the indications and techniques of microsurgery.

This book has been conceived to aid eye care practitioners such as ophthalmologists and optometrists as well as other eye care or research professionals such as biologists, biochemists and medical doctors interested in the Ocular Surface. This text is divided into four main sections. The first section is dedicated towards the anatomy and physiology of the ocular surface (defining ocular surface concept, tear film structure, corneal and conjunctival anatomy, etc.). The second section covers the most common ocular surface disorders (dry eye, anterior and posterior blepharitis, keratitis, ocular allergy, cicatricial conjunctivitis, and the ocular surface alterations related with Glaucoma treatment). The third section delineates the therapeutic care of these disorders, including topical, systemic and surgical treatment options and the fourth section addresses the relationship of the ocular surface and contact lenswear (describing the indications for contact lenses wear, their complications and managing the adverse effects related with contact lens-wear).

Many books from symposia describe the current status in well established fields of research, where much is known and where the loose ends are only details in the picture. The topic dealt with here does not fall into this pattern. The study of time as a parameter in its own right is difficult, and the loose ends tend to do minate the present picture. Although the book does provide the reader with an overview of the field, its main value is probably to act as a source of "food for thought" for those interested in the function of sense organs and nervous systems as substrates for behaviour. The Introduction is intended to provide the readers of the book with a short guide to the topiCS discussed in the different chapters. The rather detailed Index may help those looking for information on specific topiCS. The Index also explains most of the abbreviations used in the book. The basic idea of the Danavox symposia is to invite a small group of experts to discuss a rather narrow theme in sound communication. The small number of active par tiCipants has the advantage of encouraging intense dis cussions and of avoiding overloading the program. On the other hand, selecting the partiCipants is difficult."

In a concise and contemporary new edition, the Oxford American Handbook of Ophthalmology offers highly practical yet evidence-based guidance on the diagnosis and management of ophthalmic disorders. Incorporating a systematic approach, the authors present common and/or important manifestations of the full spectrum of eye diseases. Included are useful summaries of common signs and symptoms, etiologies, diagnostic testing, and therapeutic regimens, as well as information on pre-, peri-, and post-operative eye care. The Oxford American Handbook should prove useful and relevant to residents and fellows in ophthalmology, as well as medical students, primary care physicians, comprehensive ophthalmologists, and other ophthalmic personnel, all who seek a ready reference for daily clinical practice and review.

The Seventh International Visual Field Symposium organized by the Interna tional Perimetric Society was held in Amsterdam, The Netherlands, September 6-10,1986. In many respects it was an exciting and fruitful meeting. The number of participants was greater than ever. The number of papers was too great to accommodate all of them. The quality of the papers reflects the continuously rising interest in perimetry in general and in automated perimetry in particular. Last but not least the social programme was organized in the, by now, almost classical friendly, enjoyable and humouristic style of the International Perimetric Society. This created an atmosphere of openness and free exchange of informa tion whICh was clearly also felt in the scientific sessions. The scientific part was divided in seven sessions with 44 spoken papers and a separate postersession during which the 46 posters were discussed. The major themes of the meeting were 'The influence of media-disturbances on the visual field' and 'Advances in perimetry in glaucoma with special emphasis on pro gression'. The session on 'media' provided interesting information on how the visual field was effected by preretinal filters. The authors either studied the influence of lens or corneal opacities or simulated opacities by special filters placed in front of the eye. In two papers the effect of cataract was qualified by photography or stray light measurements."

The condition known most widely as pseudotumor cerebri syndrome is of diagnostic interest and clinical importance not just to neurosurgeons, but also to neurologists, ophthalmologists and headache specialists. Variously called idiopathic intracranial hypertension, benign intracranial hypertension, and other names over the century or so since it was first recognised, the authors argue for the grouping of all these conditions under the name of pseudotumor cerebri syndrome on the basis of a common underlying mechanism - an impairment of CSF absorption due to abnormalities at the CSF/venous interface. The book reviews the development of ideas around some of the more contentious issues and deals in depth with aetiology, investigative findings and strategies, treatment and outcome, and in the concluding chapter, considers the possibility of establishing an experimental model to facilitate analysis of the unresolved issues, and pointing the way to a more complete understanding of this controversial condition.

Advances in the study and understanding of myasthenia gravis have led to the need for the publication of this important new edition. The goal of Myasthenia Gravis and Related Disorders, Second Edition is identical to the first -- to provide the clinician and the scientist with a common resource for understanding this complex disorder. This new edition begins with discussions of neuromuscular junction structure and function and follows with updated chapters covering a wide range of topics, such as the acetylcholine receptor, clinical presentation, diagnostic evaluation, and treatment. Importantly, new supplemental chapters have been added; these discuss rigorous clinical assessments of patients for research trials and the epidemiology and genetics of myasthenia gravis. The discussion of the most challenging aspects of myasthenia gravis, its impact on patients psychological make-up, has been expanded as well. Myasthenia Gravis and Related Disorders, Second Edition retains the personal approach of the authors regarding treatment and is a valuable resource for meeting the many and varied needs of patients with myasthenia gravis."

The surgical correction of refractive vision errors has dramatically and continually changed over time. The evolution of laser vision correction has been aided by advancements in the technology, growing experience, and improved understanding of the eye and its response to surgery. However, not all refractive errors can be treated with the laser. Phakic IOLs: State of the Art is designed to provide the advances in phakic IOL technology and techniques, ideal for physicians who treat many of the patients who are not candidates for laser vision correction. The collaboration of Dr. Lucio Buratto, Dr. Stephen G. Slade, and Dr. Nicola D. Hauranieh, along with a team of international surgeons, has produced a complete book specifically aimed to improve the treatment and therefore the quality of vision of patients. Phakic IOLs: State of the Art is designed for ophthalmologists interested in learning the concepts, developing the skills, and preparing for phakic IOL procedures. This book contains a detailed description of the basic technique of the operations, as well as the special techniques devised by the international contributors. Richly illustrated with over 200 images that demonstrate the various concepts, readers are able to develop a more thorough understanding of phakic IOL implantation. This definitive resource couples both the authors’ and contributors’ diverse experience and knowledge to produce a complete resource of vision correction with phakic IOLs. Expert ophthalmologists interested in being on the cutting edge and enhancing their surgical skills, as well as new physicians, will benefit from adding Phakic IOLs: State of the Art to their personal library.

"Essentials in Ophthalmology" is a new review series covering all of ophthalmology categorized in eight subspecialties. It will be published quarterly, thus each subspecialty will be reviewed biannually.
Given the multiplicity of medical publications already available, why is a new series needed? Consider that the half-life of medical knowledge is estimated to be around 5 years. Moreover, it can be as long as 8 years between the first description of a medical innovation in a peer-reviewed scientific journal and publication in a medical textbook. A series that narrows this time span between journal and textbook would provide a more rapid and efficient transfer of medical knowledge into clinical practice, and enhance care of our patients.

This third volume of "Uveitis and Immunological Disorders" in Essentials in Ophthalmology provides up-to-date, relevant information for the reader. Our knowledge and understanding of immune mechanisms has increased exponentially over the past few years and has expanded to disorders such as diabetic retinopathy and macular degeneration. This volume will provide the ophthalmologist with practical information on how to diagnose and treat these difficult, and in some cases, blinding disorders. In addition, there are important discussions of the mechanisms underlying these conditions, which incorporate the most recent, up-to-date research material available. "Summary for the Clinician" and "Core Messages" sections enhance the value of each chapter. This volume was written by authors who are leaders in their field. Important and provocative questions dealing with recent developments are raised. Topics covered include:

Matching in Penetrating Keratoplasty

Acute Anterior Uveitis and HLA-B27: What's new?

What can the aqueous humour tell us about Uveitis?

Is Diabetic Retinopathy an inflammatory disease ?

Steroid sensivity in Uveitis

This volume discusses the background and various clinical applications of radiation therapy in the treatment of non-malignant diseases. It documents the radiobiological and physical principles of treatment and the rationale underlying the use of radiotherapy for various disorders of the CNS, head and neck, eye, skin and soft tissues, bone and joints, and vascular system. In so doing, it draws attention to and elucidates the scope for application of radiotherapy beyond the treatment of malignancies. Both the risks and the benefits of such treatment are fully considered, the former ranging from minor clinical problems to life-threatening diseases.
