Vergence Eye Movements

Chapter

Abstract

  • When we shift our gaze from a far object to a near object, our eyes converge, the lenses of our eyes modify their focus (accommodate), and our pupils often constrict. These three combined responses are termed the near triad. This article first reviews the geometrical aspects of changing gaze in depth and how, in natural environments, convergence and accommodation demands co-vary. A schematic of the two systems and how this co-variance is reflected in neural cross-links is then introduced. The final section reports our current anatomical and functional knowledge of the systems involved in the near triad and their interconnections. © 2009 Elsevier Ltd All rights reserved.
