U.S., April 16 -- ClinicalTrials.gov registry received information related to the study (NCT06929026) titled 'Retinal Biomarkers in Parkinson's Disease' on March 31.
Brief Summary: The goal of this observational study is to determine whether oxygen content of the retinal vessels of the eye may serve as a biomarker in Parkinson's disease. The main questions it aims to answer are:
1. Is retinal vessel oxyhemoglobin saturation and vessel width altered in people with Parkinson's disease?
2. Is the thickness of the retinal nerve fiber layer altered in people with Parkinson's disease?
