Effect of visual training on the vertical vergence amplitude

K M Robertson et al. Am J Optom Physiol Opt. 1985 Oct.

Abstract

Visual training has an effect on the vertical vergence amplitudes. Three mature symptomatic patients exhibited a significant increase in the vertical vergence which compensates for the vertical heterophoria. Subjects with normal binocularity and hence no vertical heterophoria did not exhibit increased vertical vergence amplitudes after training.
