Meta-analysis reveals those who have visual impairments or are blind have a higher risk of mortality compared to peers with better vision. The study found mortality risk was 29% higher in those with mild visual impairment and rose to 89% higher for those with severe visual impairments.
A new retinal implant that works in conjunction with camera-equipped smart glasses and a microcomputer provides blind people with "artificial vision" by stimulating retinal cells.
Loneliness, stress, and social isolation as a result of COVID-19 exacerbated and intensified visual hallucinations in blind people with Charles Bonnet Syndrome by 56%.
Humans use the primary visual cortex to process sounds in the dark. This not only occurs in those with sight but also those who were born blind.
A visual cortical prosthesis can restore sight by bypassing damage to the eyes and delivering visual information retrieved from a camera directly to the brain.
A new study provides compelling evidence that congenital blindness and early cortical blindness may decrease the risk of developing schizophrenia. Researchers believe the protective effect may be related to compensatory cortical reorganization.
Researchers have developed a 3D printed prototype for a bionic eye. The team successfully printed an array of light receptors onto a hemispherical surface. This advance could revolutionize restoring vision to those who have lost their sight.
Researchers report blind people need additional timing cues to accurately judge relative locations of sounds, but those without visual impairments who were blindfolded could judge the relative location of sounds independently from timing cues.
Recovering from suddenly losing her vision, Vanessa Potter experienced a mingling of her senses and altered the way in which she saw colors.
CRISPR gene editing has allowed researchers to prevent angiogenesis of the retina occurring in mice. Researchers say the new technology could help prevent vision loss in those with retinal diseases.
