Dyslexia: the link with visual deficits
BJW Evans, N Drasdo, IL Richards - Ophthalmic and physiological optics, 1996 - Elsevier
Some research reports suggest that visual anomalies may have a causative role in dyslexia,
and on this basis certain forms of therapy have been proposed. Recently, we have
published the initial results of a matched group study which found dyslexia to be associated
with binocular instability, reduced amplitude of accommodation, and reduced contrast
sensitivity for both low spatial frequencies and uniform field flicker. The binocular instability
was best identified by measuring the vergence amplitude: a modified Dunlop test faired to …
