In plain words

What the trial is, and whether it could suit you

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 measures. The knowledge gained will allow us to find the most beneficial stimulation location and parameters for improving binocular coordination and vergence while preserving the ability to treat motor symptoms in Parkinson's disease.
