Getting old isn't all it's cracked up to be. Sure, you get a hefty discount at the Country Kitchen Buffet. But you also suffer from stuff like age-related macular degeneration (AMD), a retinal disease that afflicts more than 10 million people a year in the US alone. There's hope for the eyes of America's elderly, though: A new pea-sized ocular implant can restore vision to the those who have lost it.
As you may recall from learning what happens when you stare at the sun, the macula acts as a focal point for incoming light, and produces a majority of your central detail vision. For reasons still unexplained, this the part of the retina may stop functioning with age, resulting in AMD—the leading cause of legal blindness Americans over 60.
