Optimization of Visual Information Presentation for Visual Prosthesis [PDF]
International Journal of Biomedical Imaging, 2018 Visual prosthesis applying electrical stimulation to restore visual function for the blind has promising prospects. However, due to the low resolution, limited visual field, and the low dynamic range of the visual perception, huge loss of information ...

Visual Prosthesis: Interfacing Stimulating Electrodes with Retinal Neurons to Restore Vision [PDF]
Frontiers in Neuroscience, 2017 The bypassing of degenerated photoreceptors using retinal neurostimulators is helping the blind to recover functional vision. Researchers are investigating new ways to improve visual percepts elicited by these means as the vision produced by these early ...

The application of computer vision to visual prosthesis [PDF]
Artificial Organs, 2021 AbstractA visual prosthesis is an auxiliary device for patients with blinding diseases that cannot be treated with conventional surgery or drugs. It converts captured images into corresponding electrical stimulation patterns, according to which phosphenes are generated through the action of internal electrodes on the visual pathway to form visual ...

Attitudes of potential recipients toward emerging visual prosthesis technologies [PDF]
Scientific Reports, 2023 With the advent of multiple visual prosthesis devices to treat blindness, the question of how potential patients view such interventions becomes important in order to understand the levels of expectation and acceptance, and the perceived risk-reward ...

Visual and Non-Visual Navigation in Blind Patients with a Retinal Prosthesis. [PDF]
PLoS ONE, 2015 Human adults with normal vision can combine visual landmark and non-visual self-motion cues to improve their navigational precision. Here we asked whether blind individuals treated with a retinal prosthesis could also benefit from using the resultant new

Reading visual Braille with a retinal prosthesis [PDF]
Frontiers in Neuroscience, 2012 Retinal prostheses, which restore partial vision to patients blinded by outer retinal degeneration, are currently in clinical trial. The Argus II retinal prosthesis system was recently awarded CE approval for commercial use in Europe.

IEEE Transactions on Biomedical Engineering, 2016 Glaucoma is a neurological disorder leading to blindness initially through the loss of retinal ganglion cells, followed by loss of neurons higher in the visual system. Some work has been undertaken to develop prostheses for glaucoma patients targeting tissues along the visual pathway, including the lateral geniculate nucleus (LGN) of the thalamus, but ...

Simulations of Electrode Placement for a Thalamic Visual Prosthesis [PDF]
IEEE Transactions on Biomedical Engineering, 2009 In this paper, placement parameters for microstimulation electrodes in a visual prosthesis are evaluated based on retinotopic models of macaque and human lateral geniculate nucleus. Phosphene patterns were simulated for idealized microwire electrodes as well as for currently available clinical electrodes.

Perception, 2008 There are more than forty million blind individuals in the world whose plight would be greatly ameliorated by creating a visual prosthesis. We begin by outlining the basic operational characteristics of the visual system, as this knowledge is essential for producing a prosthetic device based on electrical stimulation through arrays of implanted ...
