title: [Postnatal development of visual functions in primates].
abstract: The author presents the results of experimental investigations performed in apes in which he evaluated the development of the visual system. Immediately after the birth the animal's lids were stitched together, first in one eye than in the second one; at the same time the first one was opened. Electrodes were then introduced surgically to the region of the lateral geniculate bodies and to the brain cortex. The function of the visual pathways and of the visual cortex were evaluated by using differential visual stimuli. Greatest changes were seen by the author in the visual cortex. He feels that the process of formation of the visual reaction in apes is finished around the second month of life. On the basis of these investigations he discusses the mechanisms of origination of amblyopia ex anopsia in children. He encourages the earliest possible examination of the visual acuity in babies and the undertaking of treatment of amblyopia before the 1st year of life.
