Retinal Prosthesis for the Blind

Survey of Ophthalmology, 2002
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 different designs of visual prostheses are named according to their locations (i.e., cortical, optic nerve, subretinal, and epiretinal). Visual loss caused by outer retinal

Retinal Prosthesis

Annual Review of Biomedical Engineering, 2005
▪ 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 nerves, prototype retinal prostheses have been tested in blind humans and have demonstrated the capability to elicit the sensation of light and to give test subjects the ...

Minimally Invasive Retinal Prosthesis

2006 IEEE International Solid State Circuits Conference - Digest of Technical Papers, 2006
A wireless retinal implant with a low-power area-efficient stimulator chip features an ASK demodulator, single-ended-to-differential converter, low-power DLL and programmable current drivers. The chip dissipates 1.3mW from plusmn2.5V at a data rate of 100kb/s.
