Normal Binocular Vision: Theory, Investigation and Practical Aspects

Normal Binocular Vision: Theory, Investigation and Practical Aspects

David Stidwill, Robert Fletcher

ISBN: 978-1-118-78868-4 January 2014 Wiley-Blackwell 280 Pages


Binocular vision, i.e. where both eyes are used together, is a fundamental component of human sight. It also aids hand-eye co-ordination, and the perception of the self within the environment. Clinical anomalies pose a wide range of problems to the sufferer, but normal binocular operation must first be understood before the eye specialist can assess and treat dysfunctions.

This is a major new textbook for students of optometry, orthoptics and ophthalmology, and also of psychology. Chapters span such key topics as binocular summation, fusion, the normal horopter, anatomy of the extra-ocular muscles, oculomotor control, binocular integration and depth perception.

Fully illustrated throughout, the book includes self-assessment exercises at the end of each chapter, and sample experiments in binocular vision functioning.

"Overall, this book is admirable and largely successful in its aim of providing a manageable theoretical background for the binocular vision student or clinician, and as such I can recommend it to any optometrist who feels a little unsure or rusty in this area." (Optician, 10 February 2012)
