Researchers at Université Laval have discovered that the retina the light-sensitive tissue at the back of the eye responds differently to light stimuli in people with early-stage Parkinson’s compared to healthy individuals.

By the time a person consults a doctor because of motor problems such as tremors, the disease has been present for several years and the affected neurons are already engaged in an irreversible degenerative process.

This “retinal signature” could serve as a biomarker for early detection.
