Eye Movements in Specific Developmental Dyslexias

Overview

Specific developmental dyslexia belongs to most frequent learning disorders. At the present time there are many proofs that dyslexia is not just a functional disorder, but it includes a neurobiological cause. In the subsequent review article the authors summarize abnormities of ocular movements, observed in subjects suffering from dyslexia during reading and solving nonverbal tasks, their pathophysiological importance and relation to present theories of dyslexia. The authors arrive at the conclusion that neuropsychological heterogeneity of subjects with dyslexia is reflected in findings of ocular movement abnormalities. These abnormalities should in some cases serve for screening of pre-school children or to select subgroups of dyslexic patients to specific rehabilitation.

Key words:
