Who this trial is looking for
This trial is looking for people with Parkinson's disease who have had deep brain stimulation (DBS). Participants will help researchers understand how brain stimulation can improve eye movement for better vision.
Are You a Good Fit for This Trial?
You may be able to join if
- I have Parkinson's disease and have undergone bilateral STN DBS.
- I can provide pre-operative MR images and can get post-operative MRI or CT scans.
- I am at Hoehn and Yahr stage 2-4 when off medication.
- I have a stable regimen of antiparkinsonian medication and DBS settings.
You may not be able to join if
- I have had previous surgical therapy for Parkinson's disease other than DBS.
- I have dementia.
- I have untreated depression or anxiety that is clinically significant.
- I have clinical features suggesting atypical parkinsonism.

About This Trial
Inability to align and refocus the eyes on the objects at different depths, i.e., vergence impairment, frequently affects the quality of life in patients with Parkinson's disease. Our study aims to understand the location-specific effects of subthalamic region deep brain stimulation on vergence by integrating the patient-specific deep brain stimulation models and high-resolution eye-tracking measu…
