December 30, 2006 Hour 1: Dr. Robert Abel answers questions about vision health.

None of the organs in the body work independently – they all work together and that's especially true of the eyes.  Today, we welcome back Dr. Robert Abel, a leading ophthalmologist, to answer questions about vision.  We'll talk about the development of retinal chips that may be the answer for macular degeneration, and a new study on mice that indicates it may be possible to reverse diabetes.   Dr. Abel takes calls.
