Implantation of Modular Photovoltaic Subretinal Prosthesis.
BACKGROUND AND OBJECTIVE Establish the surgical procedure for subretinal implantation of multiple photovoltaic arrays for the restoration of sight. MATERIALS AND METHODS Multiple silicon photovoltaic arrays of 1 mm in diameter and 30 µm in thickness were implanted subretinally via single retinotomy in rabbits. Ophthalmoscopic imaging and optical coherence tomography (OCT) were used to validat...
متن کاملIn-vivo Performance of Photovoltaic Subretinal Prosthesis
We have developed a photovoltaic retinal prosthesis, in which camera-captured images are projected onto the retina using pulsed near-IR light. Each pixel in the subretinal implant directly converts pulsed light into local electric current to stimulate the nearby inner retinal neurons. 30 m-thick implants with pixel sizes of 280, 140 and 70 μm were successfully implanted in the subretinal space...
متن کاملSubretinal implantation of Okayama University-type retinal prosthesis (OURePTM) in canine eyes by vitrectomy
Okayama University-type retinal prosthesis (OURePTM) is a photoelectric dye-coupled polyethylene film which generates electric potential in response to light and stimulates nearby neurons. This study aims to test surgical feasibility of subretinal implantation and functional durability of dye-coupled films in the subretinal space. The dye-coupled films were implanted subretinally by 25-gauge vi...
متن کاملRestoration of Sight with Photovoltaic Subretinal Prosethesis
Patients with retinal degeneration lose sight due to gradual demise of photoreceptors. Electrical stimulation of the surviving retinal neurons provides an alternative route for delivery of visual information. Subretinal photovoltaic arrays with 70m pixels were used to convert pulsed near-IR light (880-915nm) into pulsed current to stimulate the nearby inner retinal neurons. Network-mediated re...
متن کاملThe subretinal microphotodiode array retinal prosthesis.
This article is also accessible online at: http://BioMedNet.com/karger To the Editor: We are concerned to read the recent article by Zrenner et al. [1]. While developing an artificial retina is a laudable goal, the publication of this article raises serious questions. The fundamental concern that we have is that the article creates the overall impression that the concept of placing a semiconduc...
