Chris Owen--yes, your intro of your mother did reach the list--I'm not sure how helpful I can be, but I was struck by the doc telling her there's nothing wrong with her eyes. This is the answer Peter gets, too. There are definite PD-related eye problems--difficulty "tracking" across the page, blurred vision, blepharitis of the lids, but apparently not anythingthat shows up as "trouble" on the exam--except the blepharitis. It seems to be more a matter of *functional* problems which are perceived subjectively by the PWP. The extreme sleepiness also is a problem Peter struggles with. He *usually* falls asleep sooner or later when I read to him,because he can't read for long now! We got the talking books from the Library of Congress, but they put him to sleep :-( so we gave up on that. The diziness I can't speak to, but I hope someone else will. Welcome to the list, and I hope we can be mutually helpful. Camilla Flintermann,CG for Peter,78/7 Oxford,OH<[log in to unmask]>
