| Abstract: | EPs elicited by diffuse light flashes and check patterns, were studied in children and juveniles with congenital and traumatic cataract, during different periods and various durations of deprivation, as well as in a control group of children and juveniles with normal vision. Specific age characteristics were found in the EPs to check patterns in seven years-old children. In children with congenital cataracts significant changes in the shape and amplitude-temporal EP parameters were recorded. In children with traumatic cataracts, presumably developed after the end of the sensitive period, the changes in EPs were much less pronounced. The obtained data are discussed from the point of view of the duration of the sensitive period of the formation of the visual function in humans and of informative value of different EP components. |
