A Rare Case of Bilateral Incomplete Duane’s Syndrome with Synkinesis of the Levator and Lateral Rectus

ABSTRACT

In the last few decades, Duane’s syndrome (DS) has begun to be classified under as one of the congenital cranial dysinnervation syndromes (CCDDs), as its primary cause is neurogenic. Incomplete forms of DS have been described very recently. This case appears to be the first report of the association of an incomplete DS with synkinesis of the levator and lateral rectus as a severe and complex example of a CCDD.
