A Prospective Study to Evaluate the Correlation Between Oculometric Measurements and Clinical Endpoints in PD Patients

A Cross-Sectional Study to Evaluate the Correlation Between Oculometric Measures and MDS-UPDRS in Patients With Idiopathic Parkinson's Disease (PD) and Evaluation of Oculometric Measures in Healthy Participants

This is a prospective study in a cohort of about 500 patients with Idiopathic Parkinson's disease, examined routinely in the neurological outpatient clinic.

This study aims to evaluate the correlation between oculometric measures and clinical endpoints. Subjects will be evaluated following a physician examination.The evaluations will include MDS-UPDRS examination, as well as an oculometric evaluation for eye movements. In addition, 500 healthy subjects will be evaluated.

This is a prospective study in a cohort of patients with idiopathic PD who are visiting the Parkinson's outpatient clinic. The aim of the study is to evaluate the correlation between oculometric measures and MDS-UPDRS score in subjects who meet the inclusion criteria and who provide a signed Informed Consent.

This study is designed to evaluate the correlation between oculometric measures and the Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS). Subjects will be evaluated at their visit to the clinic. The evaluations will include an MDS-UPDRS examination by a certified neurologist and other tests. In addition, all patients will undergo a NeuraLight session for oculometric evaluation along with eye-tracking recordings. All assessments will be performed during a clinic visit unless authorized to be conducted remotely. In addition, 500 healthy subjects will be evaluated, undergoing a NeuraLight session for oculometric evaluation along with eye-tracking recordings.
