Ptosis secondary to amyloidosis of the tarsal conjunctiva and tarsus.

Abstract

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