FINALLY some mass awareness of the visual dysfunction associated with PD. These multiple visual problems along with depression were a major component of my initial "package" of presenting issues. Several opthalmologists (including prominent academicians) did not comment on the problem and others stated that "convergence insufficiency" was NOT related to the PD. My "basket" of problems included extreme discomfort (car sick with headache) which accompanies any serious attempt to concentrate, read or track (store or bookshelves). I have been through all the various therapeutic efforts (prisms, limited correction of blended progressive lenses, exercises, medication manipulations, tinted lens filters, eye patch etc) without improvement. Reading attempts are limited to rapid scanning. Ken Janis, MD
