title: Vitreous Amyloidosis as the Presenting Symptom of Familial Amyloid Polyneuropathy TTR Val30Met in a Portuguese Patient.
abstract: Familial amyloid polyneuropathy (FAP) is a group of disorders characterized by the extracellular deposition of amyloid substance in various tissues. The peripheral nervous system and the heart are the main target organs, but the eye may also be involved. We report a case of vitreous amyloidosis as the first manifestation of FAP in a 66-year-old Portuguese man without a family history.
