Early Detection of Visual Impairments

摘要: The immature visual system of human infants or animals is known to be capable remarkable plasticity in response functional structural interferences with normal development. Experimental studies the ontogeny defects such as amblyopia loss binocular vision cat and monkey have led concept “sensitive period” early development, during which particularly susceptible abnormal influences (1,2). Early deprivation has been shown result behavioural, electrophysiological, morphological neuronal changes may lead permanent impairments functions. On other hand, very often also allows reversal by appropriate treatment. In humans, existence a sensitive period for input restrictions, well treatment resulting deficits generally accepted, although its time course still largely unknown. detection therefore important not only diagnostic purposes, but interest optimal therapeutic effect.
