Journal ArticleDOI
Photovoltaic retinal prosthesis with high pixel density
Keith Mathieson,James Donald Loudin,Georges Goetz,Philip Huie,Lele Wang,Theodore I. Kamins,Ludwig Galambos,Richard Smith,James S. Harris,Alexander Sher,Daniel Palanker +10 more
TL;DR: A photovoltaic subretinal prosthesis is presented, in which silicon photodiodes in each pixel receive power and data directly through pulsed near-infrared illumination and electrically stimulate neurons.
Journal ArticleDOI
Photovoltaic restoration of sight with high visual acuity
Henri Lorach,Georges Goetz,Richard Smith,Xin Lei,Yossi Mandel,Theodore I. Kamins,Keith Mathieson,Philip Huie,James S. Harris,Alexander Sher,Daniel Palanker +10 more
TL;DR: It is demonstrated that subretinal implants with 70-μm-wide photovoltaic pixels provide highly localized stimulation of retinal neurons in rats, and the ease of implantation of these wireless and modular arrays opens the door to the functional restoration of sight in patients blinded by retinal degeneration.
Journal ArticleDOI
Photovoltaic retinal prosthesis: implant fabrication and performance
Lele Wang,Keith Mathieson,Keith Mathieson,Keith Mathieson,Theodore I. Kamins,James Donald Loudin,Ludwig Galambos,Georges Goetz,Alexander Sher,Yossi Mandel,Philip Huie,Daniel Lavinsky,James S. Harris,Daniel Palanker +13 more
TL;DR: The fabricated device delivers efficient retinal stimulation at safe near-infrared light irradiances without any wired power connections, which greatly simplifies the implantation procedure.
Journal ArticleDOI
Selectivity of direct and network-mediated stimulation of the retinal ganglion cells with epi-, sub- and intraretinal electrodes.
TL;DR: These results define the optimal range of pulse durations, pulse polarities and electrode placement for the retinal prostheses aiming at direct or network-mediated stimulation of RGCs.
Journal ArticleDOI
Cortical responses elicited by photovoltaic subretinal prostheses exhibit similarities to visually evoked potentials
Yossi Mandel,Georges Goetz,Daniel Lavinsky,Philip Huie,Keith Mathieson,Lele Wang,Theodore I. Kamins,Ludwig Galambos,Richard Manivanh,James S. Harris,Daniel Palanker +10 more
TL;DR: Implant-induced eVEP has shorter latency than visible light-induced VEP, its amplitude increases with peak irradiance and pulse duration, and decreases with frequency in the range of 2-20Hz, similar to the visible light response.
