Abstract Amyloidosis of the vitreous body is a rare disorder that causes progressive visual loss. In this report, a 36‐yr‐old female with familial amyloidosis is described in whom a progressive reduction of vision in both eyes over the last 4 yr was ascribed to vitreous opacities due to amyloid. A left pars plana vitrectomy was performed and an aspirated sample of the vitreous on cytologic examination showed vitreous strands admixed with abundant dense, pink, globular material which was intensely positive on Congo red staining and exhibited yellowish‐green birefringence indicative of amyloid. This was further confirmed ultrastructurally, which showed the classical appearance of amyloid fibrils. The case is of interest not only in view of the rarity of the condition but also in view of the fact that as far as we are aware the cytodiagnosis of amyloid from an aspirate sample from the vitreous has not been previously described in the literature.
