Double Vision| Binocular

Double vision that resolves with one eye closed


  • Any process that affects ability of eyes to move in a coordinated fashion
  • Can be due to cranial nerve issue: e.g. stroke, tumor, mass impinging on CN3, 4 or 6
  • Can be due to NMJ or muscle issue: e.g. myasthenia, muscle entrapment in orbital fx


  • Resolves when one eye closed
  • Present when look in direction of impaired movement, resolves when look in directions of preserved movement

Physical Exam Findings

  • Exam to assess for level of dysfunction of CNs and/or extra-occular muscles that move eye→ loss of coordinated bilateral movement
