Since the last edition of this book, new medications have been developed and glaucoma medical therapy has evolved substantially. Clinicians need to understand, synthesize, and apply the latest information about these medications to the best advantage of their patients. Currently available glaucoma medications have been approved for clinical use based on their ability to lower intraocular pressure, but these drugs may have other adverse and potentially beneficial effects that are relevant to clinicians. The focus of this book is to provide information about currently available drugs for medical therapy of glaucoma.This is a peer-edited, multiauthor book, with chapters contributed by experts in the field of glaucoma. The contributors have provided evidence-based information and offered their perspectives from clinical experience as well as their own clinical and basic research experience. The book is intended to provide information about glaucoma medical therapy for practicing clinicians and clinicians in training as well as basic scientists with an interest in clinical ophthalmology.
