Official title
Relationship Between Symptom Severity, Retinal Morphology, and the Nigrostriatal Dopamine System in the Brain in Parkinson's Disease
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
