Visual tracking, optokinetic aging

Have any of you come across any studies which have looked at
optokinetic tracking and the blurring speed (visual tracking limits)
in the elderly population. Lewinson (1990) used a 3-D optical
scanner (basically a projector) to test the blurring speed of young
dyslexic and non-dyslexic groups. He suggested that this tracking
ability was a measure of cerebellar functioning and found it to
correlate with measures of Romberg balance. Also, both cerebellar
abilities had discriminative validity and distinguised dyslexic and
Aging is associated with declines in balance and visual tracking (if
you want references ask me, I'll send you a chapter). But I have not
found studies which specifically use the blurring speed methodology.
Have any of you?
Give us a hand here folks.
