Journal Article
Human neural retinal transplantation.
Mark S. Humayun,Eugene de Juan,Manuel del Cerro,Gislin Dagnelie,Wolfgang Radner,Srinivas R. Sadda,Constancia del Cerro +6 more
TL;DR: Although a definite positive effect on visual function could not be demonstrated, the apparent high tolerance for graft tissue is promising for future efforts in the field of neural retinal transplantation.
Journal ArticleDOI
Intraocular retinal prosthesis
James D. Weiland,Mark S. Humayun +1 more
TL;DR: In this paper, the epiretinal implant was used to restore some level of visual function to blind individuals. But, the retinal response to stimulation was not investigated. And, it was not shown that the implant still allowed test subjects to perform simple visual tasks.

Flexible electrode array for artificial vision
Peter Krulevitch,Dennis L. Polla,Mariam Maghribi,Julie Hamilton,Mark S. Humayun,James D. Weiland +5 more
TL;DR: In this article, an implant consisting of a polymer substrate made of a compliant material such as poly(dimethylsiloxane) or PDMS was used to stimulate the retina.
Journal ArticleDOI
In vitro and in vivo evaluation of ultrananocrystalline diamond for coating of implantable retinal microchips
Xingcheng Xiao,Jian Wang,Chao Liu,John A. Carlisle,Brian V. Mech,Robert J. Greenberg,Dilek Guven,R. Freda,Mark S. Humayun,James D. Weiland,Orlando Auciello +10 more
TL;DR: In this work, ultrananocrystalline diamond (UNCD) thin films were evaluated for use as hermetic and bioinert coatings for a retinal microchip and it was concluded that UNCD is a promising candidate for Use as the encapsulating Coatings for implantable retinalmicroelectronic devices.
Journal ArticleDOI
Frequency and amplitude modulation have different effects on the percepts elicited by retinal stimulation.
Devyani Nanduri,Ione Fine,Alan Horsager,Geoffrey M. Boynton,Mark S. Humayun,Robert J. Greenberg,James D. Weiland +6 more
TL;DR: It is suggested that frequency modulation improves the encoding of a wide range of brightness levels without a loss of spatial resolution.
