Abstract
Preterm diplopic children (SD) frequently suffer pedagogical difficulties. They showed visual perceptual impairments end also constructional dysphasia, neuropsychologically. Multiple regression analysis proved that the constructionald yspraxia was independent from the impairments of visual acuity, stereoacuity, depth perception and visual perception. EEG coherence analysis in SD patients disclosed lower interhemispheric coherence at alpha band frequency in occipital derivations. The lower coherence value may correspond to thinning of posterior body and splenium of corpus callosum in SD patients. A adequate ophthalmological treatments, books with enough space between the lines and three dimensional models to facilitate the image of stereography are recommended.
