Study Summary

The purpose of this study is to examine if a correlation exists between findings from brain imaging studies of the status of the dopamine system in the brain using DaTscan and SPECT imaging, clinical symptoms of Parkinson's disease, and changes in the structure of the retina as detected by optical coherence tomography (OCT) in recently diagnosed and more advanced Parkinson's disease patients.

Primary Outcome

OCT measures including measurements of the thickness (microns) of specific retinal layers including RNFL, ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer, outer nuclear layer, photoreceptors, and retinal pigment epithelium.
