Eye movements of two patients with Duane's retraction syndrome (type 1)
were recorded using high-resolution infrared oculography. Slowed hypometric
abduction was found. The dynamics of adducting saccades in the affected
hypometric eye were normal, suggesting an absence of functional
cocontraction of the medial and lateral rectus muscles. Therefore,
narrowing of the palpebral tissue on adduction most likely reflects a
reorganization of the central ocular motor pathways.
