I've read that because Parkinson's is caused by the death of dopaminergic neurons in the brain, the same process could be affecting dopaminergic cells in the eye, which do exist. This might be what they're seeing. Thoughts?

"I've read that because Parkinson's is caused by the death of dopaminergic neurons in the brain" Not to nitpick, but it's my understanding that we all lose dopaminergic neurons in the Substantia Nigra as we get older. Some people lose them a a lot faster, and they develop what we call "Parkinsons". There is also presence of Alpha Synuclein in the dysfunctional dopaminergic neurons, which are not generally present in the "non-parkinsons" population...
