A number of research groups are develo** electrical implants that can be attached directly
to the retina in an attempt to restore vision to patients suffering from retinal degeneration …

Electrical activity of electrogenic cells in neuronal and cardiac tissue can be recorded by
means of microelectrode arrays (MEAs) that offer the unique possibility for non-invasive …

A subretinal visual implant (Alpha IMS, Retina Implant AG, Reutlingen, Germany) was
implanted in 29 blind participants with outer retinal degeneration in an international …

A light-sensitive, externally powered microchip was surgically implanted subretinally near
the macular region of volunteers blind from hereditary retinal dystrophy. The implant …

Purpose: We assessed the safety and efficacy of a technically advanced subretinal
electronic implant, RETINA IMPLANT Alpha AMS, in end stage retinal degeneration in an …

This study aims at substituting the essential functions of photoreceptors in patients who are
blind owing to untreatable forms of hereditary retinal degenerations. A microelectronic …

Retinal prostheses have been developed to fight blindness in people affected by outer
retinal layer dystrophies. To date, few hundred patients have received a retinal implant …

▪ Abstract Retinal prostheses represent the best near-term hope for individuals with
incurable, blinding diseases of the outer retina. On the basis of the electrical activation of …

Most of current concepts for a visual prosthesis are based on neuronal electrical stimulation
at different locations along the visual pathways within the central nervous system. The …

It has been demonstrated that electrical stimulation of the retina can produce visual percepts
in blind patients suffering from macular degeneration and retinitis pigmentosa. However …
