TL;DR: These results demonstrate for the first time that subretinal micro-electrode arrays with 1500 photodiodes can create detailed meaningful visual perception in previously blind individuals.
Journal ArticleDOI

TL;DR: The data show that subretinal implants can restore visual functions that are useful for daily life in patients who are blind owing to untreatable forms of hereditary retinal degenerations.
Journal ArticleDOI
Spatial resolution and perception of patterns mediated by a subretinal 16-electrode array in patients blinded by hereditary retinal dystrophies.
Robert Wilke,Veit-Peter Gabel,Helmut G. Sachs,Karl-Ulrich Bartz Schmidt,Florian Gekeler,Dorothea Besch,Peter Szurman,Alfred Stett,Barbara Wilhelm,Tobias Peters,Alex Harscher,Udo Greppmaier,Steffen Kibbel,H. Benav,A. Bruckmann,Katarina Stingl,Akos Kusnyerik,Akos Kusnyerik,Eberhart Zrenner +18 more
TL;DR: Subretinal electric stimulation can yield reliable, predictable percepts, enabling blind persons to recognize shapes and discriminate different letters, and Stimulation paradigms must be optimized to further increase spatial resolution.
Journal ArticleDOI
Population receptive field analysis of the primary visual cortex complements perimetry in patients with homonymous visual field defects

TL;DR: Functional magnetic resonance imaging is used to measure area V1 population receptive field (pRF) properties in five patients with partial or complete quadrantic visual field loss as a result of partial V1+ or optic radiation lesions, yielding information about the functional properties of spared-V1 cortex not provided by standard perimetry mapping.

TL;DR: In this article, a subretinal implant with two distinct arrays, a multiphotodiode array (M PDA) with 1500 electrodes, each electrode being controlled by an adjacent photodiode and an amplifier within a 3 x 3x0.1 mm chip, as well as a second one with 16 electrodes s on a 1.2 x 1.6mm array, for direct stimulation (D S) directly controlled from outside.
