Doctors have a new tool for fighting a devastating disease that threatens to close the window to the world for more than 2 million Americans.
The disease is macular degeneration which causes blindness slowly, robbing vision first from the middle of the eye.
But at Johns Hopkins, scientists are implanting a tiny telescope into the eye - and what sounds like science fiction is bringing amazing results.
"The advantages of the telescope are that people can see detail much more clearly: people's faces, television, looking out into the world," said Judith Goldstein with the Wilmer Eye Institute
While this form of treatment has been approved by the FDA, doctors say it is not a cure and it requires intense rehabilitation to retrain the brain.
