Betterhumans - Age-related Blindness Gene Found:
"A variation in a single gene may cause half of all cases of age-related macular degeneration (AMD), the leading cause of blindness in the elderly.
The finding provides insight into a disease thought to affect about 30% of all Americans over 75. Affecting the macula, the area in the retina where light is focused and converted to nerve signals, AMD destroys the central vision required to do such things as read and drive."
