Will retinal implants restore vision?
A number of research groups are developing electrical implants that can be attached directly to the retina in an attempt to restore vision to patients suffering from retinal degeneration. However, despite promising results in animal experiments, there are still several major obstacles to overcome before retinal prostheses can be used clinically.
متن کاملReversible thermosensitive glue for retinal implants.
PURPOSE To determine in vitro effects of a plasma polymerized N-isopropyl acrylamide (pNIPAM) coating for thermally controllable adhesion to retinal tissue. METHODS Polyimide (50 microm), parylene C [poly(monochloro-p-xylylene)] (20 microm), and poly(dimethyl siloxane) (PDMS) (200 microm) coated with pNIPAM were used as implant materials to test retinal adhesion in enucleated pig eyes. Follow...
متن کاملMicrosensors and microbiosensors for retinal implants.
This paper concentrates on recent developments in microsensors and microbiosensors for the possible applications in visual prostheses, especially retinal prosthetic devices. A brief introduction on the developments of visual prosthesis will be presented. The importance for in-vivo pH measurements as well as the need for an implantable pH sensor will be demonstrated. Electrochemical biosensors d...
متن کاملRetinal implants: emergence of a multidisciplinary field.
PURPOSE OF REVIEW This review summarizes the current status of retinal prostheses, recent accomplishments, and major remaining research, engineering, and rehabilitation challenges. RECENT FINDINGS Retinal research, materials and biocompatibility studies, and clinical trials in patients blind from retinitis pigmentosa are representative of an emerging field with considerable promise and soberi...
متن کاملRetinal prostheses: progress toward the next generation implants
In the last decade, various clinical trials proved the capability of visual prostheses, in particular retinal implants, to restore a useful form of vision. These encouraging results promoted the emerging of several strategies for neuronal stimulation aiming at the restoration of sight. Besides the traditional approach based on electrical stimulation through metal electrodes in the different are...
