Familial amyloid polyneuropathy in a Sri Lankan family.

A woman who presented with features of peripheral sensory, motor and autonomic neuropathy and amyloid deposits in the vitreous due to familial amyloid polyneuropathy (FAP) is described. Her father had died of a similar illness and one of her brothers and her two children had lesions suggestive of early amyloid deposits in the vitreous. Reports of familial amyloidosis are rare from Asian countries and it has not been reported in Sri Lanka previously.
