Abstract

Aim: To review evidence from the literature on the effect of concomitant strabismus on saccadic eye movements and saccade adaptation. To consider how analysis of such eye movements may provide infor­mation about the link between the coordination of saccades and binocular vision.

Method: A literature-based review of saccades in strabismus is presented.

Results: Saccade characteristics are in general unaffected by the presence of concomitant strabismus in the absence of amblyopia. The literature also documents no significant change to saccade perfor­mance following surgical intervention to the extraocular muscles despite evidence of altered velocity- profiles. The main effect on saccades in strabismus is disconjugacy, which is significantly increased. There is evidence that disconjugate saccade adaptation, however, is intact in strabismus, suggesting that fusion may not be necessary for activating the adaptive mechanism.
