Proteinaceous film without macrophages covering lens implant in acute panophthalmitis
Ophthalmic Surgery
|September 1, 1985
Abstract:
A very well-preserved capsule-like proteinaceous film continuously covering a Copeland lens implant in a late stage of alpha streptococcus panophthalmitis exhibits neutrophils and fibrin as well as massive pus on its outer surface. But no macrophages, fibroblast-like cells, or giant cells are found. The proteinaceous film has resisted the proteolytic actions of the massive pus present on and around the implant.
Insights
A proteinaceous film protected a Copeland lens implant from bacterial infection, resisting pus and proteolytic enzymes during severe alpha streptococcus panophthalmitis. This protective film prevented cellular infiltration, highlighting its role in implant survival.
Area of Science:
- Ophthalmology
- Microbiology
- Biomaterials Science
Background:
- Late-stage alpha streptococcus panophthalmitis can lead to severe intraocular infection and potential implant failure.
- The host's immune response typically involves inflammatory cells and enzymatic degradation of foreign materials.
