Basing a Parkinson’s diagnosis on blurry vision and dizziness is medical malpractice! Are you sure you had a neurologist? The MOST IMPORTANT type of doctor to see is a MOVEMENT DISORDER SPECIALIST. Yes, Parkinson’s can cause eye problems (I had double vision two years before I was diagnosed.). Tremor is absent in a minor number of people . It is not necessary for a diagnosis. Parkinson’s can cause a whole host of seemingly unrelated problems…..e.g. lack of arm swing, constipation, foot dragging-tripping, tremor on one side, sebborheic dermatitis, anxiety and depression, maybe a fall or two, and on and on and on. My family doctor finally sent me to get a DATSCAN. It clearly showed evidence of dopamine loss on one side of the sustantia nigra . This , however, can only rule out essential tremor. It could be a “Parkinsonian” type of problem..e.g. Parkinson’s, Multiple System Atrophy, or Progressive Supranuclear Palsy. Get a better doctor, get referred to a Movement Disorder Specialist, and get back to this site. Good luck!
