Duane's syndrome is a congenital type of strabismus characterized by the inability of one eye to turn outwards. Other names for this condition include:

  • Duane's Retraction Syndrome;
  • Eye Retraction Syndrome;
  • Retraction Syndrome;
  • Congenital retraction syndrome; and
  • Stilling-Turk-Duane Syndrome.

This conditions results in the inability to maintain binocular vision when looking towards the side of the affected eye. In day to day life this is generally well compensated for by head turn to avoid diplopia but may result in an unusual head posture. The possibility of diplopia is however of concern to flight safety.
