Duane retraction syndrome (DRS) is a congenital disorder of eye movement that occurs in approximately 1 in 50 patients with strabismus. This condition prevents horizontal eye movement, with absence of outward movement and deficiency of inward movement. Normal ocular motility depends on precise relations between cranial motor neurons and their target, extraocular muscles. In DRS patients, absence of the abducens motor neurons and aberrant innervation of extraocular muscles by third cranial nerve have been reported.
