Diagnostic Considerations

Disorders similar in presentation to Duane syndrome (DS) can be acquired as a result of trauma or following localized infection of the orbit leading to inflammation and consequent mechanical restrictions of eye movement. In such cases, a thorough history will usually help in distinguishing between these conditions. In the clinical setting, the principal difficulties in differential diagnosis arise as a consequence of the very early age at which patients with this condition first present. The clinician must be persistent in examining abduction and adduction, as well as in looking for any associated palpebral fissure changes or head postures, when attempting to determine whether what often presents as a common childhood squint is, in fact, Duane syndrome. Fissure changes and the other associated characteristics of Duane syndrome, such as upshoots or downshoots and globe retraction, are also vital when deciding whether any abduction limitation is the result of Duane syndrome and not a consequence of cranial nerve VI or abducens cranial nerve palsy.
