Orientation and mobility assessment in retinal prosthetic clinical trials

Research output: Contribution to journalArticle

Abstract

PURPOSE.: The purpose of this study was to develop an orientation and mobility (O&M) assessment protocol to implement in subjects who have been implanted with an artificial silicon retina (ASR), and to use this experience to propose a research agenda for O&M with prosthetic vision. METHODS.: A controlled and naturalistic assessment was developed that included walking a prescribed obstacle course and travel to and from a hospital cafeteria. Subjects were tested before and 3 and 6 months after being implanted with the ASR. Outcome measures were walking speed and number of contacts with obstacles. The experiences from this study led to a proposed research agenda in O&M. RESULTS.: Eight subjects with retinitis pigmentosa participated in this study. The vision status of the subjects ranged from
