Normal Binocular Vision
Theory, Investigation and Practical Aspects

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.
