Researchers have developed a cornea implant from the collagen protein of pig skin. The implant restored the vision of 20 people with diseased corneas. The new implant could be a viable alternative to human cornea transplantation.
Cognitive tests that rely on vision-dependent tasks may skew results for up to 25% of adults over 50 with undiagnosed visual problems such as AMD and cataracts. This may lead to a misdiagnosis of mild cognitive impairment in older adults.
Researchers have developed a new "brain window" that allows for longer-term studies to map the visual areas of the brain.
Providing free or low-cost vision care and eyeglasses to children helped improve academic performance and behavior, researchers report.
Smoking marijuana affects several key visual functions, including 3D vision and contrast sensitivity. However, 90% of cannabis users believe the drug has either no, or minimal, effect on their visual abilities.
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.
Researchers say children with visual problems such as amblyopia may face developmental issues in brain areas responsible for attention.
Researchers investigate advances in BCI and consider the implications of linking our brains up to technology.
Researchers discover those who were born blind use a brain map, similar to that in people with full vision, to distinguish between objects.
Researchers bioengineer a retina that from synthetic and biological tissue. The development could revolutionize the bionic implant industry.
Researchers report children with poor vision experience an improvement in their peripheral vision within hours of being exposed to child friendly action video games.
A new study reveals a possible cause of visual impairment in astronauts.
