PERFLUORODECALIN-INDUCED INTRAVITREAL INFLAMMATION

Abstract

OBJECTIVE: To report an unusual case of intravitreal inflammation in a human eye caused by the presence of residual perfluorodecalin in a case of giant retinal tear and retinal detachment. METHODS: The posterior capsule of the lens, which was infiltrated with deposits, was collected during surgery. The specimen was stained with hematoxylin and eosin, with periodic acid-Schiff, and for melanin. Part of it was examined with electron microscopy. Immunohistochemical staining was performed to demonstrate CD68 antigens, cytokeratin, and glial fibrillary acid protein. RESULTS: Vacuolated macrophages and retinal pigment epithelial cells infiltrated the posterior capsule. Electron microscopy showed the presence of membrane-lined vacuoles within the macrophages. A monolayer of epithelial cells covered the cellular infiltration. CONCLUSION: Residual perfluorodecalin can induce an intraocular chronic macrophage response.
