Models of Vergence and Accommodation-Vergence Interactions

  • Chapter
Models of the Visual System

Abstract

Vergence (or disjunctive) eye movements provide single vision by bringing the images of a bifixation target onto corresponding retinal points in the two eyes. When a target moves in depth, the brain recognizes the change in position of the retinal images and drives the extraocular muscles to bring these images into proper register on the retinas. Since vergence eye movements reflect the function of the brain, quantitative assessment of these movements can reveal fundamental information regarding the brain’s underlying neural control strategy. For this reason, an understanding of how vergence is controlled in both normal and symptomatic individuals has been one of the most important goals of vision scientists, clinicians, and bioengineers. This chapter provides a summary of some of the most significant research on modeling of the vergence system, as well as the interactions between accommodation and vergence.
