Ophthalmic Toxicology

Thoroughly revised and updates, this new edition of Ophthalmic Toxicology retains its uniqueness in covering all aspects of ophthalmic toxicology. With chapters from leading authorities incorporating the latest developments in the field, including a new chapter on the molecular basis of ophthalmic toxicity, this edition covers such topics as: *t

This volume represents the proceedings of the Fifth Congress of the International Society of Ocular Toxicology (ISOT), which was held at the Grove Park Inn and Resort in Asheville, North Carolina, October 13-17, 1996. We are delighted to present this volume to the ophthalmic community, especially those with a significant interest in ocular toxicol ogy. The Fifth Congress was developed around themes relating to ocular drug metabolism, the ocular pathophysiological effects of nitric oxide, government issues relating to the use of alternative methods for toxicity testing, and a workshop that encompassed comparisons of both in vitro versus in vivo models as well as different animal models. The outcome of this congress, embodied in this volume, is a contribution to the methodologies currently employed or under development and to various drug or physical effects on different ocular tissues. While the focus of this proceedings is on ocular effects of drugs or other materials, many of the contributions deal with topics that have a much broader interest. The workshop concerning the use of different model systems and the choice of the best animal model for drug testing covers a wide range of interests that ex tends far beyond specific ocular effects. This is especially true in the area of alternative methods and in the choice of the best animal model for examination of different disease entities.

This book is an international effort to standardize the language, terms, and methods used in ocular toxicology.With over 300 color illustrations this consensus volume provides standards and harmonization for procedures, terminology, and scoring schemes for ocular toxicology. it is essential for industry, pharmaceutical companies, and governmental agencies to help improve the drug development process and to reduce and refine the use of animals in research. Standards for Ocular Toxicology and Inflammation is endorsed by the American College of Veterinary Ophthalmologists.

On behalf of the editorial board and the organizing committee of the 4th congress of the International Society of Ocular Toxicology (I SOT), held in AnnecyNeyrier du Lac, France, October 9 -13, 1994, we are pleased to present to the ocular toxicology community this indexed volume of our congress proceedings. The 4th congress was designed primarily to facilitate and update the knowledge in ocular electrophysiology and ocular pharmacokinetics, in both the clinical and preclinical aspects. The outcome of this 4th congress, established in this volume, is a useful contribution to the meth odology in both fields and will hopefully assist in the evaluation and interpretation of ocular findings recorded in animal studies on drugs and other chemicals, in order to protect human health. Undoubtedly, work on the mechanisms of ocular toxicology in the process of pharmaceutical development must continue and these proceedings, embodying the presented papers, will add to the data base. The editors, the congress organizing committee and the members of the International Society of Ocular Toxicology thank the speakers who gave their time, knowledge, and expertise to assist us in this project. The following manuscripts contain the main substance of each of the platform presentations and, in some cases, much more. Moreover, our thanks go to all the participants coming from a range of background- regulatory, academic and industrial -for their attention and excellent contributions during the discussion.

Ocular toxicity is routinely assessed in toxicology studies conducted for regulatory purposes. Ocular anatomy and physiology and the assessment of ocular toxicity itself can be challenging to scientists involved in the safety assessment of pharmaceuticals, pesticides and other agents. Anatomical and physiological differences between species can impact the nature of ocular effects observed following intended or unintended exposure of ocular tissues to xenobiotics. Ocular Toxicity in Laboratory Animals provides a concise reference addressing ocular anatomy and physiology across species that will enhance the design and interpretation of toxicology studies conducted for regulatory purposes. The book provides an overview of routine and advanced techniques that are used to assess ocular toxicity including slit lamp biomicroscopy, indirect ophthalmoscopy, electrophysiology and imaging methods for the anterior and posterior segments of the eye. Additionally, the book defines the regulatory expectations for pharmaceuticals intended to treat ocular diseases and for other non-pharmaceutical regulated chemicals. With contributions from experts in the field, Ocular Toxicity in Laboratory Animals is an authoritative, accessible guide for toxicologists and other scientists involved in conducting toxicology studies for regulatory purposes and/or reviewing data from such studies.

The purpose of this book is to present a synopsis of what is known about substances that have toxic properties injurious to the eyes, disturbing to vision, or affecting eyes in other unwanted ways. The coverage is truly comprehensive, encompassing local and systemic, acute and chronic, human and veterinary toxicology of the eye. The text summarizes mechanisms of injury, treatments, and other relevant knowledge for more than 3000 alphabetized substances - essentially all those on which public information is available. Also described are systemic side effects of ophthalmologic drugs, treatment of chemical burns of the eyes, and testing methods and species specificity for toxic effects on the eyes. Facilitating access to this prodigious amount of information is a large index that cross-references substances and effects, including numerous synonyms. This monumental work is a truly definitive text and a highly useful reference book that should be available to every ophthalmologist, emergency room, and medical library.

Dermal and Ocular Toxicology: Fundamentals and Methods is a procedurally-oriented volume of detailed methods and practical examples discussing the dermal and ocular aspects of toxicology. The book is divided into a dermal section and an ocular section. Each section begins with a chapter on the anatomy and physiology of each organ system and then progresses to more specialized chapters discussing such topics as the toxicological pathology of each system, state-of-the-art in vitro and in vivo evaluatory procedures, statistical considerations for test design and data interpretation, and the utilization of test findings. Test methods are provided for acute dermal exposure effects, dermal hypersensitivity and photoallergy assessment, dermal and ocular 0.pharmacokinetics, skin flap and skin grafting techniques, and in vitro alternative methods. This book can be used as an instructional text or as a sourcebook for practicing toxicologists, pharmacologists, industrial hygienists, occupational health professionals, and graduate students.
