Abstract Details


Report ocular manifestations in late onset familial amyloid polyneuropathy (FAP) patients.


Hospital de Santo Ant├│nio - Centro Hospitalar do Porto


retrospective observational consecutive case series of 20 late onset FAP patients. Demographic data, TTR mutation envolved, age at begining of disease, period of evolution of disease, liver transplant or medical treatment, ophthalmological alterations and previous ocular surgeries were evaluated.


Thirteen patients were female. The mean onset age was 58 years and average evolution time of the disease was 5,6 years. All patients were TTR Met30 and 2 patients were compound heterozygous TTR met30 met119. Four patients had been submitted to liver transplant and nine were on Tafamidis® treatment. Amyloid deposits on anterior lens surface were observed in 15 eyes (37,5%), scalloped pupil in 8 eyes (20%) and vitreous opacities in 23 eyes (57,5%). Nine had underwent vitrectomy. Glaucoma was present in 13 eyes and 4 have been submitted to surgery.


Ocular manifestations are common in late onset FAP patients. Vitreous opacities were the most frequent specific alteration. Ophthalmologist has an important role in follow-up of FAP patients to accurately treat sight-threatening manifestations.
