We present a clinical pathological review of vitreous amyloidosis in a case of familial amyloidotic polyneuropathy, type I. Vitreous opacifi cation was the first manifestation of disease in the proband, who was successfully treated with vitrectomy. The eyes were obtained at autops y after the patient died from an unrelated cause, and the histopatholo gy is presented here.
