Brief Summary
The objective is to determine the prevalence of visual dysfunction in People with Parkinson's Disease (PwP). The investigators will administer the: Visual Impairment in Parkinson's Disease Screen and Revised-Self-Report Assessment of Functional Visual Performance. Patients seen at Fixel Institute and their caregivers will be invited to participate. Responses to the 2 questionnaires will help determine prevalence rates of visual dysfunction in PwP compared to those both with and without other neurological conditions.
