Advances in Retinal Therapeutics
In recent years there have been monumental and exciting advances in the treatment of retinal disease which made a special issue on advances in retinal therapeutics relevant and interesting. Indeed, in this issue there are 11 papers reporting either original basic or clinical research findings or reviewing the literature and reporting recent developments. The papers in this issue are on a wide r...
متن کاملStimulator Design of Retinal Prosthesis
This study focuses on the design of electrical stimulator for retinal prosthesis. The stimulator must be designed such that the occurrence of electrolysis or any irreversible process in the electrodes and flexible lead is prevented in order to achieve safe stimulation over long periods using the large number of electrodes. Some types of biphasic current pulse circuits, charge balance circuits, ...
متن کاملOptogenetic approaches to retinal prosthesis
The concept of visual restoration via retinal prosthesis arguably started in 1992 with the discovery that some of the retinal cells were still intact in those with the retinitis pigmentosa disease. Two decades later, the first commercially available devices have the capability to allow users to identify basic shapes. Such devices are still very far from returning vision beyond the legal blindne...
متن کاملRetinal prosthesis for the blind.
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 degeneration in diseases such as retinitis...
متن کاملPredicting visual sensitivity in retinal prosthesis patients.
PURPOSE With the long-term goal of restoring functional vision in patients with retinal degenerative diseases, the eyes of blind human subjects were implanted chronically with epiretinal prostheses consisting of two-dimensional electrode arrays that directly stimulated cells of the neural retina. METHODS Psychophysical techniques were used to measure the brightness of electrically generated p...
