Abstract
Experimental results from step stimulation of the two major dynamic components in ocular vergence showed that while fusional covergence dominated a coordinated binocular vergence movement, accommodative convergence always contributes to the dynamic response. A quantitative analysis of component dynamics, both in isolation and during coordinated movements, indicates that these components are additive at least through a portion of the movement. Two alternative hypotheses are presented for the role of accommodative convergence during the period immediately following a binocular vergence movement.
