Summary of measurements of ratio of peak velocity of bad eye/peak velocity of good eye for upward and downward saccades of the group of control subjects (CS) and P1-4, who had monocular loss of vision early in life.

<p>Box plot conventions are similar to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0056556#pone-0056556-g001" target="_blank">Figure 1</a>. Perfectly conjugate saccades would have a ratio of 1.0. Upward saccades made by the patients are generally more conjugate than downward saccades.
