[Familial amyloid polyneuropathy type I complicated by chronic glaucoma: 3 cases].

Purpose: We report 3 cases of familial amyloid polyneuropathy type I (FAP) with amyloid infiltration of the vitreum and glaucoma.

Patients And Methods: We reviewed the records of three patients, 2 females and one male, aged 41, 47 and 83 years respectively. The 3 patients had familial amyloid polyneuropathy type I with vitreous infiltration and open angle glaucoma. The two women underwent a liver graft four years earlier. Vitrectomy allowed confirmation of the diagnosis in the 83-year-old patient. Two patients underwent trabeculectomy, histological analysis of the iris and the trabeculum was obtained for one patient.

Results: The tree patients presented a polyneuropathy, vitreous infiltration and open angle glaucoma. Results of light microscopy of the iris and the trabeculum showed amyloid deposits in the iris and the trabecular meshworks.

Conclusion: Familial amyloid polyneuropathy is a hereditary disease which may have a wide range of ocular manifestations. Glaucoma is among the most serious complications of familial amyloid polyneuropathy.
