title: Introduction to the Symposium on Basic and Clinical Aspects of Vergence Eye Movements.
abstract: The basic aspects of vergence eye movements revolve about a central theme of a critique of the Maddox classification. Topics include interactions between accommodation and convergence in the absence of visual stimuli, dynamic properties of accommodative and fusional vergence, interactions between vergence eye movements and other visual motor systems, violations of Hering's law associated with specific components of vergence, and sources of fixation disparity. The clinical reports examine the effectiveness of disparate and accommodative stimuli for driving vergence eye movements in strabismus with normal or anomalous binocular correspondence. Effectiveness of dynamic and static tests of vergence eye movements is compared for detection of general binocular dysfunction. The Symposium is concluded with an open discussion of the basic and clinical reports.
