Figure 4.

Mean gain values (average of rightward and leftward eye movements) obtained from the eye’s peak velocity between saccades. All the data were obtained from the participants’ right eye with the exception of control participant C17 who reported diplopia and whose left eye datum is shown as a black open square and the right eye’s as a grey filled square. For all the other participants in both the control and AMD groups, there were no significant differences in gain between the two eyes. The dashed lines show the expected average gain of 1.17 (Equation (1)).
