Horner's Syndrome

Horner's syndrome is the classic triad of:
  • ptosis
  • miosis
  • anhydrosis

Causes include:
  • stroke
  • lateral medullary syndrome (Wallenberg syndrome)
  • syrinx
  • carotid dissection or aneurysm
  • MS
  • Pancost tumour
  • trauma

Treatment depends on the cause.

Topical cocaine can be used to confirm Horner's syndrome; normal pupils dilate in response to topical cocaine while in Horner's they do not.
