The Present book is designed to provide authoritative, comprehensive, concept regarding glaucoma and drug utilization research.The purpose of the book is to emphasize the practical aspects of medical therapy for glaucoma. In the present era, newer and newer drugs are introduced every year and doctors are in dilemma to select and prescribe rational, cost effective medicine depending upon the individual requirements. With this book, we have attempted to highlight two important aspects: medical therapy and cost effectiveness of prescribed drugs. We are hopeful that the book will be helpful for all researchers, Doctors, nurses and paramedical staff. Lastly Suggestions and criticism are most welcome. Rajesh Kumar Suman
