Discussion: Normal and Abnormal Visual Development
von Noorden: Dr Garey has shown that development is more complete in the monkey at birth than in the human, especially as far as the lateral geniculate nucleus is concerned. There may be clinical significance in this finding. Maybe this is one of the reasons why naturally occurring strabismus is limited to humans. If the human visual system is as immature for the first 3–4 months as Dr Held has shown us, it may be especially vulnerable to peripheral influences, perhaps from the brainstem, that may interfere with the development of normal ocular motor coordination.
