Completely updated and revised, this new edition of Pickwell's classic text has been greatly expanded to form the definitive reference work on binocular vision anomalies. This text keeps the theory of binocular vision to the minimum necessary to understand the investigative and therapeutic procedures. It covers investigations of binocular vision anomalies, heterophoria, strabismus, and incomitant deviations. Includes chapters on examining young children, as well as on binocular instability, and also contains a glossary of orthoptic terminology and abbreviations, which is useful to students preparing for examinations. -- Copyright © 1999 Book News, Inc., Portland, OR All rights reserved --This text refers to the Hardcover edition.
