Sensory and motor fusion

The basis of our understanding of binocular vision and amblyopia in clinical practice has not changed much since Claud Worth formulated three grades of binocular vision in 1903 – well over a century ago. Despite many scientific advances in the neuroanatomical and neurophysiological aspects of binocular vision it may – or may not – come as a surprise that the treatment of strabismus and amblyopia has not fundamentally changed since.

This part of the Special Interest Symposium “contains nothing new” [p.1 Squint: its causes, pathology and treatment. Worth C. London, John Bale, Sons & Danielsson Ltd, 1903], to an extent, but is intended as a refresher of the anatomical and physiological basis of binocular vision and to prime the attendants for the symposium's subject: the presentation of recent advances in the research of the corpus callosum and its role in binocular vision.
