This book describes the voyage through the evolution of trabeculotomy, culminating in the global appeal of Gonioscopy Assisted Transluminal Trabeculotomy or GATT. It honors the giants in the field who came before us and the many authors who have contributed and adapted GATT to their healthcare systems. As the collective worldwide knowledge from this book is disseminated, we hope the information will guide surgeons to the next best step in the evolution of circumferential trabeculotomy.

Purpose: Gonioscopy-assisted transluminal trabeculotomy (GATT) has been shown to reduce the intraocular pressure (IOP) and medication burden in eyes with open angle glaucoma (OAG) and congenital glaucoma; however, evidence in young and middle-aged adults remains limited. Here we report the surgical outcomes related to GATT with and without concomitant cataract surgery in young and middle-aged patients. Study Design: Retrospective interventional case series.Methods: Eyes of patients between 18 and 65 years of age that underwent GATT were included. Success was defined as IOP u226421mmHg with a reduction u226520% compared to baseline and absence of additional glaucoma surgery or loss of light perception. Changes in IOP, medication burden, and best-corrected visual acuity (BCVA) were assessed using generalized linear models. Safety measures included adverse events and complications.Results: 21 eyes of 18 patients with a mean age of 45.34u00b113.94 years and a minimum of 6-month follow-up (16 with one-year follow-up) were included. Glaucoma diagnoses included 8 primary OAG, 6 juvenile OAG, 4 uveitic glaucoma, 2 angle recession glaucoma, and 1 pigment dispersion glaucoma. 15 eyes underwent GATT and 6 received GATT combined with cataract surgery (CE-GATT). The 12-month cumulative survival was 81%. IOP decreased significantly from 28.57u00b110.54 mmHg to 13.11u00b13.70 (54% reduction, p

Preface Childhood is the topic of the ninth World Glaucoma Association Consensus. There has been only sparse attention to the diagnosis and treatment of childhood glaucoma. Both pediatric ophthalmologists and glaucoma specialists provide care for such children. In some instances, they manage these individuals alone and, in others, the management is shared. For this consensus, the participation of both groups was solicited. The global faculty, consisting of leading authorities on the clinical and scientific aspects of childhood glaucoma, met in Vancouver on July 16, 2013, just prior to the World Glaucoma Congress, to discuss the reports and refine the consensus statements. As with prior meetings, it was a daunting task to seek and obtain consensus on such a complicated and nuanced subject. It is unclear how each of us decides how we practice, and evidence to guide us often is sparse. It is remarkable how few high level studies have been conducted on the management of childhood glaucoma. Hence, this consensus, as with the others, is based not only on the published literature, but also on expert opinion. Although consensus does not replace and is not a surrogate for scientific investigation, it does provide considerable value, especially when the desired evidence is lacking. The goal of this consensus was to provide a foundation for diagnosing and treating childhood glaucoma and how it can be best done in clinical practice. Identification of those areas for which we have little evidence and, therefore, the need for additional research also was a high priority. We hope that this consensus report will serve as a benchmark of our understanding. However, this consensus report, as with each of the others, is intended to be just a beginning. It is expected that it will be revised and improved with the emergence of new evidence. Robert N. Weinreb, Chair

It is evident that in the last couple of years there has been a surge of interest in research in the fi eld of glaucoma surgery. This includes research in the improvement of conventional glaucoma surgery; trabeculectomy, and glaucoma drainage devices, as well as research in more recently introduced surgical methods and their emplacement in our range of surgical therapeutic options. Modulation of wound healing, a factor of paramount importance, has also received its share of research interest. More recently, research has embarked on identifying different surgical approaches and alternative surg ...

Keeping up to date with advances in comprehensive ophthalmology and in the ophthalmic sub-specialties is extremely difficult because of the accelerating rapidity with which new information and technology become available and the diminishing time and opportunity for practitioners and trainees to read and learn. The first edition of Albert and Jakobiec’s Principles and Practice (1994) was conceived with the idea of utilizing an electronic, updated version in which the chapters were revised by the chapter authors on an annual or semi-annual basis, but the technology was not sufficiently advanced to achieve this goal. Subsequent editions (2000 and 2008) were organized by Saunders and the last published by Elsevier (of which Springer has obtained the complete rights to move forward with the 4th edition, see attachment). For nearly three decades, this text has provided its readers with authoritative and comprehensive coverage of clinical ophthalmology, written and edited by a group of authors who represented a “Who’s Who” in ophthalmology. By using Springer’s Meteor platform, with its ability to allow authors and editors access to updating their chapters online annually/semi-annually, and with the recruitment of select chapter authors, this work’s usefulness as the standard text in ophthalmology will be maintained and expanded upon by Springer. The 4th edition of this comprehensive and authoritative text is written by hundreds of the most distinguished authorities from around the world and edited by four leaders in the field, providing today's best answers to every question that arises in ophthalmology practice. Richly illustrated with thousands of high quality, full color, clinically-relevant images, Albert and Jakobiec's Principles and Practice of Ophthalmology, 4th Edition covers every scientific and clinical principle in ophthalmology, ensuring that the reader will always be able to find the guidance needed to diagnose and manage patients' ocular problems and meet today's standards of care. Written for practicing ophthalmologists and trainees, this book delivers in-depth guidance on new diagnostic approaches, operative techniques, and treatment options, as well as coherent explanations of new scientific concept and its clinical importance. The 4th edition will prove to be the source every practicing clinician needs to efficiently and confidently overcome any clinical challenge they may face. Updates include new chapters on anterior and posterior segment diseases, as well as chapters more focused on treatment, plus thousands of new, high-quality, color images and illustrations, updated references, and information on the most cutting-edge technology used by clinicians in their practices today. Additionally, readers will enjoy the same, user-friendly, full-color design they remember from the previous edition, complete with many at-a-glance summary tables, algorithms, boxes, and diagrams that allow the reader to locate the assistance needed more rapidly than ever.
