Many people are hindered by vision dysfunctions. One of the most prominent vergence dysfunctions in society is convergence insufficiency (CI) affecting 7% of the population. This study inspects the dynamics of convergence movements in both CI and normal binocular vergence subjects. Two stimulus types, a four degree and six degree step, were presented to all subjects. The goal was to determine if the dynamics of CI subjects were different compared to subjects with normal binocular vergence. Using the main sequence analysis, data show the dynamics of CI subjects were in the normal range as those who had normal binocular vergence, but were on the lower end. This study shows the dynamics of CI subjects, whom have not had vision therapy, are slower when initiating a convergence movement.
