Genetics aren't necessarily destiny for those with mutations thought to always cause inherited blindness, a new study says. Fewer than 30% of people with these genetic variants wind up blind, even ...

Normal human color vision at photopic light levels is trichromatic and relies on the stimulation of three types of cone photoreceptors. While intrinsically photosensitive retinal ganglion cells ...

For decades, a genetic test that turned up a mutation linked to inherited blindness was treated as a verdict, not a risk factor. Families were told that certain variants meant vision loss was ...
