As we grow older, it is normal to experience age-related eye problems. These changes are often unrelated to Parkinson's disease (PD). If you are having vision problems, it is important to visit an ophthalmologist for a full examination.

As people with Parkinson's know all too well, the disease can cause many more symptoms than those that are noticeable from the outside. Some of the lesser recognized ones -- even among doctors -- involve the eyes and visual system. Parkinson's can cause many symptoms, ranging from dry eyes to double vision. Not only can visual disturbances interfere with reading or driving, they can worsen walking or balance problems, and even contribute to hallucinations.
Vision problems can be due to Parkinson's disease (PD), the medications used to treat it, or to unrelated conditions of the eye or eyelid.
