Duane's retraction syndrome (DRS) (also known as Stilling-Turk-Duane syndrome)
- prevalence of about 0.1% of the general population
- accounts for 1% to 5% of all strabismus cases
- DRS is a congenital oculomotor anomaly
- characterized by the pathognomonic ocular motility pattern of globe retraction with simultaneous narrowing of the palpebral fissure on attempted adduction
- most cases of DRS occur sporadically
- incidence of genetic inheritance has been approximated to fall within a range between 5% and 23 %
- syndrome includes variants permitting an abduction deficiency, adduction deficiency, or a combination of the two
- often there is an associated 'tether' phenomenon consisting of over elevation, over depression, or both during adduction
- globe retraction on adduction occurs secondary to aberrant innervation
- results in cocontraction of the medial and lateral recti in the affected eye
