Bilateral Lateral Rectus Palsies in High Altitude Illness
Keywords:
Lateral rectus palsy; cranial nerve palsy; high altitude illness; diplopiaAbstract
A 50-year-old man with high altitude illness had bilateral lateral rectus palsies when he went to the Himalaya at 5,000
meters. He had no other neurological signs, except headache. He received acetazolamide, prednisone, and spent time in a
hyperbaric chamber; but unfortunately he showed no improvement. Two months later, his diplopia completely resolved itself
without any treatment, after his descent to a lower altitude.
