title: Ptosis secondary to amyloidosis of the tarsal conjunctiva and tarsus.
abstract: OBJECTIVE
  To report a case of chronic unilateral ptosis in a 63-year-old, otherwise healthy woman with visual restriction.
  
  
  METHODS
  We performed a biopsy on an enlarged tarsal plate that we believed had caused ptosis. A levator aponeurotic advancement was performed subsequently.
  
  
  RESULTS
  Histologic and ultrastructural examination of the biopsy specimen disclosed amyloidosis of the tarsal conjunctiva and tarsus. There was no evidence of systemic amyloidosis.
  
  
  CONCLUSIONS
  Localized amyloidosis involving the tarsal conjunctiva and tarsus is a rare cause of chronic eyelid thickening and ptosis.
