Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for contracting the lateral rectus muscle to abduct (i.e., turn out) the eye. The inability of an eye to turn outward results in a convergent strabismus or esotropia of which the primary symptom is double vision or diplopia in which the two images appear side-by-side. The condition is commonly unilateral but can also occur bilaterally.
The unilateral abducens nerve palsy is the most common of the isolated ocular motor nerve palsies.

“our nerve filaments twitch with its presence
day and night,
nothing we say has not the husky phlegm of it in the saying,
nothing we do has the quickness, the sureness,
the deep intelligence living at peace would have.”
—Denise Levertov (b. 1923)
“All conservatives are such from personal defects. They have been effeminated by position or nature, born halt and blind, through luxury of their parents, and can only, like invalids, act on the defensive. But strong natures, backwoodsmen, New Hampshire giants, Napoleons, Burkes, Broughams, Websters, Kossuths, are inevitable patriots, until their life ebbs, and their defects and gout, palsy and money, warp them.”
—Ralph Waldo Emerson (18031882)
