FOREWORD

One of the most wonderful and stimulating aspects of modern ophthalmology is the continued spirit of ingenuity in advancing the treatment of ophthalmic disease. This is manifested by continuous research in both medical and surgical techniques in the quest to improve our patient’s vision and prevent and treat eye disease.

The ophthalmic subspecialty of glaucoma continues to be one of the most interesting and dynamic areas of ophthalmology with numerous improvements in not only the pharmacologic treatment of glaucoma but also the surgical arena.

Traditionally glaucoma has been managed with medications until the disease has progressed to a significantly advanced state requiring more than pharmacologic therapy. However, recent trends indicate that surgeons throughout the world are transitioning to a more aggressive mind set with quicker movement towards interventional glaucoma procedures and techniques that reduce intraocular pressure and treat the disease surgically.

Dr. Ashok Garg and his colleagues have compiled a brilliant book with concentration on the most novel and successful glaucoma procedures and surgeries available today. The authors, who hail from a diverse international population, have managed to come together and present a

xii Step by Step Minimally Invasive Glaucoma Surgery

thorough analysis of the latest technological modalities for treating glaucoma. Through advancements in communication and technology over the past decade these surgeons have been able to share their experiences and technologies leading to the rapid advancement of minimally invasive glaucoma surgery.

It is rare to find a text with such a complete and thorough analysis of all the different possible treatment technologies available today. I commend the editors for their diligence in assembling such a diverse and comprehensive text of glaucoma therapy and surgery. Their tireless efforts has enabled surgeons, worldwide, to assemble and share their knowledge and skills in one of the most advanced treatises on glaucoma to date.

This book serves not only as an excellent core book on treatment modalities for glaucoma but also serves to introduce and educate all glaucoma specialists to up and coming progressive technologies that they will be using for years to come.

I am sure you will enjoy this book as much as I have and in this new era of minimally invasive glaucoma surgery you will come away with a tremendous amount of knowledge and hope for the future of our glaucoma patients.

PREFACE

Glaucoma is a complex multifactorial slowly progressive neurodegenerative disorder associated with raised intraocular pressure leading to death of retinal ganglion cells and degeneration of their connected optic nerve fibers and subsequent visual loss. The aim of Modern Glaucoma Treatment is to preserve visual function with minimal side effects. Effective management of Glaucoma requires a reduction of intraocular pressure to a level appropriate for the stage of disease. There is tremendous improvement in Medical Management of Glaucoma with newer drugs but burden of daily treatment, cost factor, possible side effects and inconvenience and poor compliance leads to progression of disease inspite of early diagnosis and prompt treatment. There are lot of surgical procedures available for Glaucoma management but they have their own postoperative complications which are sometimes difficult to treat leading to the frustration of the patient. In last 5 years tremendous advances have been made specially in minimally invasive glaucoma surgery with minimal postoperative complications and better visual results.

This step by step book has been written specially to acquaint ophthalmologist with latest minimally invasive glaucoma surgical techniques. Seventeen chapters of this book are written by International known Glaucoma specialists covering MIGS specially Excimer Laser Trabeculotomy, Sclerothalamotomy, Trans-scleral Diode Laser Cyclophotocoagulation, Milling Trabeculoplasty, VDSCI, Customized Laser Assisted Filtration Surgery (CLAFS), SLT, Pneumatic Trabeculoplasty, Femtosecond Lasers and Neuroprotective Therapeutic approach. These

are all high techniques with excellent visual results available in this single Internatioonal book. An added attraction of this book is interactive CD showing all latest MIGS techniques.

We are highly grateful to Shri Jitendar P Vij (Chairman and Managing Director), Mr. Tarun Duneja, General Manager (Publishing) and all staff members of our publisher M/s Jaypee Brothers Medical Publishers (Pvt) Ltd. who took active interest in this project and prepared this handy high quality book in a short time. We are quite certain this step by step MIGS book shall be a useful companion to every ophthalmologist who do Glaucoma work.
