Jeremy,

    My best guess is that CP in some persons affect the six extrinsic eye
muscles which move the eye. The kinesthetic difference between these sets of
muscles is one of the primary sources of depth perception. This is my
speculation from a course on vision testing I took longer ago than I care to
say. LOL More recent knowledge may offer a more accurate explanation.
