The past decade has seen significant changes in our understanding of the pathophysiology of glaucoma and in our diagnostic approaches to, and management of, the disease. In this volume some of the world´s most highly regarded experts discuss areas that have seen significant improvement, as well as areas for future development. With the age of our population increasing, certain aspects of epidemiology and risk factor determination have become more important. Fluctuation of intraocular pressure may have an impact on glaucoma, and is systematically evaluated in this volume. Detecting progression is a tricky issue, and methods are being developed to use these techniques for glaucoma follow up. Angle closure glaucoma has been more precisely defined by a new terminology. The difficult topic of uveitic glaucoma is also addressed in this volume. New surgical techniques and the results of non-penetrating glaucoma surgery, as well as special shunt surgery, are described in two of the chapters. Finally, the European Glaucoma Society’s electronic glaucoma record is presented. The selection of topics, and the expertise of the authors, will help the reader understand the many faces of glaucoma and, ultimately, will contribute to better care for our patients.
