Glaucoma is a group of eye diseases causing optic nerve damage. The optic nerve carries images from the retina, which is the specialized light sensing tissue, to the brain so we can see. In glaucoma, eye pressure plays a role in damaging the delicate nerve fibers of the optic nerve. Most people don't notice these blind areas until much of the optic nerve damage has already occurred. It has been estimated that by 2020 there will be approximately 80 million people with glaucoma, an increase of about 20 million since 2010. Furthermore, it is thought that at present over 3 million people are blind due to glaucoma, a figure that is set to rise to 3.2 million by 2020 with the increasing prevalence, unless improved screening and effective treatment strategies are successful. This book aims to empower individuals by discussing important aspects of glaucoma in an accessible manner, with clear illustrations and helpful analogies. It focuses on ways the individual can take responsibility for his or her own health and live well, through being informed and practicing good self-care. While glaucoma stands at the center of this book, the concepts also apply to other diseases and life in general.
