The eyes may be a window to the brain for people with early Parkinson's disease. People with the disease gradually lose brain cells that produce dopamine, a substance that helps control movement. Now a new study has found that the thinning of the retina, the lining of nerve cells in the back of the eye, is linked to the loss of such brain cells.
