New research shows that the eyes are involved in Parkinson's Disease

The eyes have similar cells and appear to be connected to the motor center of the brain

A new treatment may be more effective than PD medication alone

This discovery could make a major difference in treating PD

The eyes may be involved in cause and progression of Parkinson's Disease

Treating Parkinson's disease through the eye may be more effective than medication alone.
