Prosthetic Vision: Where We Are Now and Where We Are Going

Recorded On: 10/25/2013

Hundreds of thousands of people worldwide suffer from retinal degenerative diseases that have left them with little or no vision. The FDA was considering the approval of a retinal prosthesis, making it imperative that optometrists understand this technology to better serve their patients. This symposium provides the most up to date information about the challenges of working with a degenerating retina for prosthetic vision, the different prosthetic vision projects going on worldwide, rehabilitation of patients with prosthetic vision, and psychological considerations for people who have received or are contemplating implantation of prosthetic vision devices.

Gislin Dagnelie, PhD, FAAO

Associate Professor

Gislin Dagnelie, Ph.D., is an Associate Professor of Ophthalmology in the Johns Hopkins University School of Medicine and the associate director of the Lions Vision Research and Rehabilitation Center, a division of the Wilmer Eye Institute. His work over the last 20 years has been supported by grants from the National Institutes of Health, National Science Foundation, Foundation Fighting Blindness, and several companies developing ophthalmic devices and visual prosthetics. Dr. Dagnelie has been the Center Principal Investigator for clinical trials of the Optobionics Artificial Silicon Retina (2004-2007) and the Second Sight Argus™ 2 retinal implant (2007-present). Since the clinical introduction of the Argus II in early 2014, Dr. Dagnelie has been managing the retinal implant program at Johns Hopkins, and acted as the Center PI for several follow-up studies of Argus II use in patients’ daily lives. His principal research effort is in understanding and measuring to what extent individuals with minimal vision can make effective use of that vision. In addition, he studies signals in the retina of retinal prosthesis patients and spearheads an effort to convert standard personal computers into precise tools for visual function measurement in the community and at home. 
Dr. Dagnelie is a native of the Netherlands, where he earned a Ph.D. in medical physics at the University of Amsterdam. In 1986, he came to the Wilmer Eye Institute for research in retinitis pigmentosa, an interest he is pursuing to this day. He is an amateur vocalist and violinist, is married to Dr. Brenda Rapp, professor of cognitive science at Johns Hopkins University, and has a 23-year old son.
