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.

This revision and reference text for pre-registration and postgraduate optometrists covers procedures for investigating heterophoria, heterotropia, vergence and accommodative anomalies, and the diagnosis of disorders of voluntary eye movement, nystagmus and supranuclear defects, paresis and non-paralytic incomitancy. Both motor and sensory anomalies are discussed together with syndromes involving oculomotor anomalies. Clinical management is outlined in protocols in an easily assimilable form. The new edition includes two new chapters on vision training and case management which will interest optometrists and orthoptists involved in sports vision, developmental vision therapy and the care of ophthalmic patients with neurological lesions. Pre-registration optometrists will find the chapters on routine orthoptic assessment and the professional qualifying examination of particular interest.
