For the millions of people with untreatable blindness the thought of a visual prosthesis that would allow them to live a normal life has always been a distant hope. There have been intermittent bright spots that periodically fan that hope such as when Dr. Dobelle's visual prosthesis patient drove a car in an empty parking lot. This book will serve as an update of the work in developing a visual prosthesis. Chapters discuss the physiologic and engineering issues, alternative strategies, and patents, as well as recent research studies.  Visual Prosthesis - A Concise Guide  is a must-have resource for ophthalmologists, neurologists, engineers and physicists.
