WebAbstract. Introduction: Fixational saccades are miniature eye movements that constantly change the gaze during attempted visual fixation. Visually guided saccades and fixational saccades represent an oculomotor continuum and are produced by common neural machinery. Patients with strabismus have disconjugate binocular horizontal saccades. Webﬁxational eye movements is the experimental observation of a highly speciﬁc correlation structure with a transition from persistent behavior (i.e., the statistical tendency of a random
