The book is designed to be immensely useful for the students and teachers of microbiology, medicine, mycology, ophthalmology, biotechnology and nanotechnology. Medical microbiology researchers in general and medical mycology in particular will find it a valuable user-friendly book.

Since the last Edition of Ophthalmology Examinations Review, there has been major new discovery in the understanding of common eye diseases, and new treatments and diagnostic procedures have been refined or newly developed.A revised Edition reflecting these changes is warranted at this time. The aim and scope of the book will be consistent with the previous two editions in that it will provide a broad review for the final year ophthalmology resident and trainees taking the specialist ophthalmology examinations. The book deals primarily with key facts and topics that are important from an examination perspective. Only information and facts that are considered relevant and critical to the exams are covered, with topics that may be of scientific interest, but are not common to exams specifically left out. This book will help the resident organize and synthesize knowledge acquired from various other sources or textbooks. While not meant to replace standard textbooks, enough information is contained within the book to serve as the main revision text nearer the exams.The style and format of this book is intentionally didactic, with questions and short answers. The answer includes a 'model opening statement,' followed by a classification system to aid organization of facts and then by the bulk of the answer in concise short notes. Exam Tips are inserted to provide an insight into how to answer different types of questions and when appropriate, a Clinical Approach section is also included.In the new edition, topics such as new understanding of disease mechanisms, new investigations (e.g. OCT), and new procedures and treatment (e.g. use of anti-vascular endothelial growth factors, new refractive surgical techniques, new corneal transplant) are covered.

There have been numerous significant developments in the diagnosis and treatment of ophthalmic tumors since the last edition of Tumors of the Eye and Ocular Adnexa. This fascicle in the Fifth Series of the AFIP Atlases of Tumor and Non-tumor Pathology includes these developments as well as abundant images to depict ophthalmic pathology. In this richly illustrated volume, the authors emphasize that the pathology of ophthalmic tumors must address not only how to make a correct diagnosis, but also how to guide the ophthalmic surgeon to a treatment plan for the disease while simultaneously preserving a patient's vision.

Even with the advances in intraocular lens technology and the growing diversity of refractive surgery techniques, the role of contact lenses in ophthalmic practice has only increased. This is due in part to the great strides in materials, technology, expanding applications (both refractive and therapeutic) for contact lenses, and the clear recognition that contact lenses will always be an important tool for the ophthalmologist. With the fitting of contact lenses as a medical art, requiring a thorough understanding of anatomy, physiology adn optics of the eye, this practice is formulaic only in part. The rest of contact lens practice requires sound medical judgment and decision- making that comes only with "hands-on" experience. The authors address this need by starting with a didactic approach that incorporates frequently-asked questions and straightforward answers so that the ophthalmology resident, intermediate contact lens practitioner, and optometrist will find this to be an indispensible resource.

Chandler and Grant's Glaucoma - one of the field's seminal texts on the medical practice and surgical management of glaucoma, now in its Sixth Edition - includes the latest updates in an area that is currently experiencing a surge of innovation.

A bright, two-color design enhances the text and aids the reader's understanding. Completely updated and revised to present the latest information in the field. All illustrations are now highlighted with a second color to aid understanding. A new color plate section provides clear, excellent-quality photographs to vividly illustrate important concepts. More information is included on aspheric lenses, with a new chapter on aspheric lenses. Many new questions and exercises reinforce important points and help readers understand the material. The contents have been entirely reorganized for a more logical, easy-to-follow approach. A new glossary defines all key terms from the chapters for convenient reference.

The visual system must extract from the light that falls on the retina meaningful information about what is where in our environment. At an early stage it analyzes the incoming sensory data along many dimensions of pattern vision, e.g. spatial frequency, orientation, velocity, eye-of-origin. Visual Pattern Analyzers provides a definitive account of current knowledge about this stage of visual processing. Nowhere else can such a comprehensive summarty of the lower level pattern analyzers be found. The book's emphasis is on psychophysical experiments measuiring the detection and identification of near-threshold patterns -- and the mathematical models, such as multidimensional signal-detection theory, used to draw inferences from such experimental results -- but neurophysiological evidence is presented and compared critically to the psychophysical evidence. Introductory material on psychophysical methods, signal detection theory, and the mathematics of Fourier analysis is gioven in order to make the book more accessible to all who are interested in the lower or higher levels of visual perception. This volume will be of great value to researchers and graduate students in the fields of vision and perception. Within the scientific community there is wide interest in the visual system, and the book will be of use to investigators in many fields, including psychophysics, neuroscience, ophthalmology and optics, computer science, and cognitive and experimental psychology.

Die Hornhauttransplantation hat sich seit der ersten erfolgreichen Keratoplastik im Jahre 1905 zu einem Routineeingriff entwickelt, trotzdem ist die Bereitstellung von Spendermaterial in Deutschland noch unzureichend. Zur Losung dieses wesentlichen Problems soll die Etablierung von Hornhautbanken beitragen. Das vorliegende Buch gibt hierfur eine Anleitung. Gleichzeitig ist es als Nachschlagewerk fur bereits auf dem Gebiet des "Eyebankings" Erfahrene gedacht. Im ersten deutschsprachigen Werk zu diesem Thema ist es den Herausgebern gelungen, fur die Beantwortung der verschiedenen Fragestellungen- von gesetzlichen Grundlagen der Hornhauttransplantation uber technische Ablaufe bei der Gewinnung und Konservierung von Transplantaten bis hin zur Finanzierung von Hornhautbanken- kompetente Autoren aus der "Arbeitsgemeinschaft Deutscher Hornhautbanken" zu gewinnen."
