This book describes advances in implantable neural stimulation technology to restore partial sight to people who are blind from retinal degnerative diseases such as age-related macular degeneration and retintis pigmentosa. Many scientific, engineering, and surgical challenges must be surmounted before widespread practical applications can be realized. The book summarizes the state of research and clinical practice in the field and reviews the current ideas and approaches of its leading researchers and practitioners.
The Editors are active researchers in the fields of artificial sight, biomedical engineering and biological physics. They have received numerous professional awards and recognition for their work. The artificial sight team at the Doheny Eye Institute, led by Dr. Mark Humayun, is a world leader in this area of biomedical engineering and clinical research.
Artificial sight is a frontier area of modern ophthalmology combining the multidisciplinary skills of surgical ophthalmology, biomedical engineering, biological physics, and psychophysical testing. Many scientific, engineering, and surgical challenges must be surmounted before widespread practical applications can be realized. The goal of Artificial Sight is to summarize the state-of-the-art research in this exciting area, and to describe some of the current approaches and initiatives that may help patients in a clinical setting. The Editors are active researchers in the fields of artificial sight, biomedical engineering and biological physics. They have received numerous professional awards and recognition for their work. The artificial sight team at the Doheny Eye Institute, led by Dr. Mark Humayun, is a world leader in this area of biomedical engineering and clinical research.Key FeaturesIntroduces and assesses the state of the art for a broad audience of biomedical engineers, biophysicists, and clinical researchersDescribes advances in microelectronics, microfabrication, surgical implantation, and psychophysical testing of visual prosthesesOutlines the promise of artificial sight and the challenges that must be met
