Stem Cells to be Tested for Macular Degeneration
By Christopher WalkerJan 4 2011
The Food and Drug Administration has approved a landmark test today to determine if Americans with macular degeneration will benefit from having an infusion of stem cells.
The study is being carried out by researchers who believe that they can end blindness with the stem cells. They have developed a set of cells that are derived from stem cells that are nearly identical to that of other eye cells.
Macular degeneration occurs after the age of 55 in most people. The cells in the eyes start to break down and become less effective. When the cells are fully degenerated they lead to blindness. The blindness starts with a small spot at the center of the eye and eventually spreads to the entire eye.
However, this is the first time that such a test has been attempted. But the researchers have said that they have corrected the vision of several rats and mice using this procedure that appears to be well designed for this type of condition.
The FDA approved the testing for ten patients that have moderate to severe macular degeneration. The test subjects will receive several infusions of the stem cells directly through the eye. Their progress will be gauged over the period of one year.
Researchers have said that if the tests are successful then it will be the first commonly used treatment for macular degeneration. At this time the FDA estimates that 10 million people suffer from some form of macular degeneration.
