Professor, Associate Director
Baltimore, MD, USA
Dr. Gislin Dagnelie is a professor in the department of ophthalmology at the Johns Hopkins University School of Medicine, and is the associate director of the Lions Vision Research and Rehabilitation Center at the Wilmer Eye Institute, where he conducts research in retinitis pigmentosa. Dr. Dagnelie's work over the last 35 years has been supported through grants from the National Institutes of Health, National Science Foundation, Foundation Fighting Blindness, and Research to Prevent Blindness, among others. He has been the principal investigator for the Optobionics Artificial Silicon Retina (2004-2007) and the Second Sight ArgusTM II retinal implant (2007-2020) clinical trials, 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, his research interests have grown to encompass a desire to understand the way people with native or prosthetic ultra-low vision (ULV) use their rudimentary sight in daily life. To further study this, he developed a targeted visual functioning questionnaire, the ULV-VFQ, as well as standardized assessments of visual performance in the real world and virtual reality. Dr. Dagnelie is a native to the Netherlands, where he earned his Ph.D. in medical physics at the University of Amsterdam.
