Can Eyes Predict Parkinson’s Disease?
Retinal thinning was linked to dopaminergic neuronal atrophy in a cross-sectional analysis, raising the possibility that it could be a way to detect pathologic changes and therefore be a disease biomarker in early Parkinson's disease (PD) patients, researchers have reported in a recently published study in the journal Neurology.

"Our study is the first to show a link between the thinning of the retina and a known sign of the progression of the disease -- the loss of brain cells that produce dopamine," the researchers have said.

Retinal thinning was found in the inferior and temporal perifoveal sectors of the PD patients, particularly the inner plexiform and ganglion cell layers, along with an association between retinal thinning and dopaminergic loss in the left substantia nigra.

The team also reported an inverse association between inner retinal thickness in the inferior perifoveal sector and disease severity (Hoehn and Yahr stage), and a positive correlation between macular sensitivity and retinal layer thickness.
