The study will help us learn more about the effects of Parkinson’s disease and/or progressive supranuclear palsy and medication on aspects of vision.
Who Can Participate
Patients with Parkinson’s disease or progressive supranuclear palsy that are doing on-off testing with their physician at Barrow Neurological Institute are eligible to participate.
Visits are estimated to take 15-20 minutes total during your standard on-off visit. Subjects will be asked to take two app-based visual tests on and off medication.
