Pars plana vitrectomy in a case of amyloidosis of the vitreous

Abstract

A pars plana vitrectomy was performed in a case of vitreous opacities caused by generalized amyloidosis. Vision improved from 2/300 to 5/5 after surgery. The vitreous specimen stained orange-red with congo-red staining and showed the typical yellow-green birefringence with polarized light. The literature on the surgical treatment of amyloidosis of the vitreous is reviewed.
