The visual system adapts to the loss of photoreception by increasing sensitivity but simultaneously becomes deleteriously hyperactive. The findings could lead to new therapies to protect vision or reverse vision loss.
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.
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.
