[Specifics of interactions of mono- and binocular mechanisms of spatial perception in cecutient children].

Interactions of mono- and binocular mechanisms of spatial perception were estimated using stereokinetic test proposed by L.N. Mogilev in 117 children with low vision and 317 healthy children aged 5-18 years old. Cecutient and healthy children had similar values of steriokinetic illusion in monocular visual conditions, while in binocular visual conditions the results were significantly different. It was shown that in children with low vision there is no increase in contribution of binocular mechanisms with aging. The mean value of coefficient K characterizing this contribution in healthy group was positive and increased from preschool age till adolescence. The mean value of coefficient K in cecutient children was negative or near zero. It is revealed that visual impairment may influence the development of mono- and binocular mechanisms of spatial perception and their interaction.
