Management of sixth nerve palsy and Duane's retraction syndrome.

In sixth nerve palsy the role of a muscle-transposing procedure, as compared with a recession-resection procedure, is discussed, and reference is made to the special problems when the palsy is the result of hydrocephalus with frequently an associated A phenomenon. In Duane's retraction syndrome, surgical treatment should be limited as a general rule to a restoration of binocular function in the primary position with elimination of the compensatory head posture, because of an understanding of the underlying anomaly of innervation.
