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 ...

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 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 ...

Artificial Vision - Visual Prosthesis
International Journal of Research in Business and Technology, 2017 A visual prosthesis is a device that captures visual images, convert light energy into electrical pulses, and deliver electrical pulses to the retina which helps blinds to restore vision artificially and uses an optogenetic approach that involves the reverse engineering of the retained visionary pathway on the visual system to become photosensitive ...

Plasticity in the visual system is associated with prosthesis use in phantom limb pain [PDF]
Frontiers in Human Neuroscience, 2013 The experience of strong phantom limb pain (PLP) in arm amputees was previously shown to be associated with structural neural plasticity in parts of the cortex that belong to dorsal and ventral visual streams.

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

Visual Prosthesis: Artificial Vision [PDF]
Medical Journal Armed Forces India, 2009 In the normal visual pathway, light travels through the tear film, cornea, aqueous, pupil, lens, and vitreous, to activate the light sensitive photoreceptors and set up the trans-synaptic connections of the retina (Fig. 1). In cases where there is gross destruction of the eye like phthisis bulbi, restoration of vision is not possible. But in conditions
