Lens implant cyto-pathology in postoperative Proteus panophthalmitis.

The reactive membrane on a posterior chamber lens implant removed from an eye with postoperative proteus mirabilis panophthalmitis was found to be based on a continuous proteinaceous capsule exhibiting only very few fibroblast-like cells. Diffusely arranged neutrophils exhibiting evidence of phagocytosis were attached to a delicate fiber network continuous with the processes of fibroblast-like cells. There was also pus and acellular debris loosely covering the outer surface of this capsule.
