Amblyopic dyslexia: a little investigated reading disorder.
We present a case of a little investigated reading disorder we call 'amblyopic dyslexia'. The reading impairment in this patient resulted from a left extrastriate and white matter lesion causing a scotomatic area of partial deficit within the right visual field. The visual deficit was consistent with cerebral amblyopia, that is, reduced form, colour, and light sensitivity without a complete loss of vision. The patient's reading deficit was characterized by accurate single letter naming and almost accurate but effortful single word reading, with no letter-by-letter strategy. The criteria for distinguishing amblyopic dyslexia from other reading disorders and the most appropriate treatment are discussed.
