TL;DR: The approach to replace retinal photoreceptors by a subretinally implanted microphotodiode array (MPDA) is summarized and electrophysiological recordings in rabbits and rats are presented which have received such subretinal implants.

TL;DR: In this paper, an active retina implant has a multiplicity of pixel elements that convert incident light into electric stimulation signals for cells of the retina with which stimulation electrodes are to make contact.

TL;DR: The fact that electrical responses were recorded from the visual cortex of pigs after electrical stimulation by subretinal electrodes and the fact that responses are also recorded in-vitro in degenerated rat retinae shows the feasibility of this approach, there are a number of open questions concerning the biocompatibility, the long-time stability, and the type of transmitted image to be solved before application in patients can be considered.

TL;DR: It is remained steadfast in the view that it is improper to imply authorship to the ideas and developments of another, whether those ideas are obtained from a patent, a published paper, a personal communication or from unpublished material.

TL;DR: Chow and coworkers published the concept of a retinal implant consisting of thousands of microphotodiodes, which is based on an implant that is placed in subretinal space and stimulates the underlying retinal cells with the photocurrents generated solely from the incident light.
