The functional interactions among brain regions in the network for saccadic eye movements would provide information on how the strabismic brains adapt to the visual deficits. Context-dependent correlation approach was used to study the functional connectivity for saccadic eye movements in both strabismic and healthy brains. Dominant negative correlations were demonstrated in strabismic brains relative to healthy brains. The connectivity findings imply the possible modulation of the functional connectivity for saccadic eye movements in a complicated network of brain regions in the frontal, supplementary, parietal and occipital eye fields, and midbrain of strabismic adults.
