Recently, a new type of visual prosthesis based on optic nerve stimulation with penetrating electrode array is developed by our group. In this presentation, we will describe the overall design principle, the technological development, and the experimental studies of the device. surgical approach to expose the optic nerve (ON), optimal site for electrode implantation, topographic distribution of the ON fibers, microvasculature distribution in ON, and biocompatibility of stimulating microelectrodes were investigated. The key issues and future challenges of visual prosthesis for blindness will also be discussed.

This lecture is available as video recording (Attachment 1 [Attach. 1]).
