Summary
This study looks at how deep brain stimulation (DBS) affects the ability to align and focus both eyes on objects at different depths in people with Parkinson's disease. Researchers will use eye-tracking and brain models to find the best stimulation settings. The goal is to improve vision without reducing the motor benefits of DBS. The study involves 40 participants who already have DBS implants.
