Primary Academic Title

Professor of Ophthalmology

Background

Gislin Dagnelie, Ph.D., is a professor of ophthalmology at the Johns Hopkins University School of Medicine and the associate director of the Lions Vision Research and Rehabilitation Center at the Wilmer Eye Institute. His work over the last 35 years has been supported by grants from the National Institutes of Health, National Science Foundation, Foundation Fighting Blindness, and Research to Prevent Blindness, among others. Dr. Dagnelie has been the principal investigator for clinical trials of the Optobionics Artificial Silicon Retina (2004-2007) and the Second Sight ArgusTM II retinal implant (2007-2020), and is the site principal investigator for the Intracortical Visual Prosthesis (ICVP) clinical trial. Through his work with recipients of the Argus II retinal implant, since 2007, he has become interested in the way people with native or prosthetic ultra-low vision (ULV) use their rudimentary sight in daily life.  To study this, he developed a targeted visual functioning questionnaire, the ULV-VFQ, and standardized assessments of visual performance in the real world and virtual reality.

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 continues to pursue.
