Abstract

The use of an eye exercise to induce a mild and tolerable nystagmus in a dysmetric dyslexic child having a cerebellar-vestibular dysfunction, and in so doing call forth compensating mechanisms in the child which are effective in improving the child's ocular fixation, sequential scanning and reading activity. The aforesaid calling forth of said compensating mechanisms beneficially provides a reflex reduction of the cerebellar-vestibular induced dysfunction of the dyslexic child. It is analogous to what occurs in amblyopia, in which compensation in the form of central functional suppression of vision in one eye is restored to in order to avoid double vision and the discomfort it gives rise to. Also, like amblyopia, if the dysfunctioning of the cerebellar-vestibular is not detected early and corrected, as by the compensation referred to, it might become irreversible in time. In one preferred form the eye exercise is one which requires dysmetric dyslexic children to track sequential stimuli moving across their line of vision at a speed just below their blurring threshold. In another form, the dysmetric dyslexic children are required to identify selected static, fixation foreground obje…
