Evaluating eye measurements and clinical assessments in Parkinson's disease

A Multicenter Longitudinal Study to Evaluate the Correlation Between Oculometric Measures and Clinical Assessment in Patients With Idiopathic Parkinson's Disease (PALOMA Trial)

Not applicable Interventional NeuraLight · NCT05862649

What this trial studies

This multicenter longitudinal study involves approximately 300 patients with idiopathic Parkinson's disease who will undergo clinical assessments and oculometric examinations at various clinical centers over a 12-month period. The study aims to evaluate the correlation between oculometric measures and clinical assessments, such as the MDS-UPDRS and MoCA scores, to determine if eye measurements can detect changes in clinical status more rapidly than current assessment tools. Participants will be assessed at five intervals (0, 3, 6, 9, and 12 months) using a novel eye-tracking system. All assessments will be conducted during clinic visits unless remote assessments are authorized.

Who should consider this trial

Good fit: Ideal candidates include men and women aged 40 to 85 with idiopathic Parkinson's disease in the early stages of the condition.

Not a fit: Patients with additional neurological diseases or those unable to comply with the study's requirements may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a faster and more accurate method for detecting clinical deterioration in Parkinson's disease patients.

How similar studies have performed: While the approach of using oculometric measures in Parkinson's disease is innovative, similar studies have shown promise in correlating eye movements with neurological conditions.
