Image Analysis for Microelectronic Retinal Prosthesis
IEEE Transactions on Biomedical Engineering, 2008By way of extracellular, stimulating electrodes, a microelectronic retinal prosthesis aims to render discrete, luminous spots-so-called phosphenes-in the visual field, thereby providing a phosphene image (PI) as a rudimentary remediation of profound blindness.

Development of Retinal Prosthesis Module for Fully Implantable Retinal Prosthesis
2010To restore visual sensation of blind patients, we have proposed a fully implantable retinal prosthesis comprising an three dimensionally (3D) stacked retinal chip for transforming optical signal to electrical signal, a flexible cable with stimulus electrode array for stimulating retina cells, and coupling coils for power transmission. For realizing the

Photovoltaic retinal prosthesis
SPIE Proceedings, 2011Electronic retinal prostheses seek to restore sight to patients suffering from retinal degenerative disorders. Implanted electrode arrays apply patterned electrical stimulation to surviving retinal neurons, producing visual sensations. All current designs employ inductively coupled coils to transmit power and/or data to the implant.

Intraocular retinal prosthesis
IEEE Engineering in Medicine and Biology Magazine, 2006Retinal prostheses have the potential to restore some level of visual function to blind individuals. While visual prosthetic devices for the optic nerve and visual cortex also have potential application, the retinal approach offers the advantage of relatively accessible retinal neurons in the back of the eye.

Retinitis pigmentosa (RP) and age-related macula degeneration (AMD) lead to the degeneration of photoreceptors, resulting in a significant visual deficit for the afflicted individual [1]. Research is proceeding to investigate the feasibility of replacing the function of the photoreceptors with an electronic device [2, 3].

Bioelectronic retinal prosthesis
SPIE Proceedings, 2016Retinal prosthesis have been translated to clinical use over the past two decades. Currently, two devices have regulatory approval for the treatment of retinitis pigmentosa and one device is in clinical trials for treatment of age-related macular degeneration.
