title: Ultrastructures of the glial epiretinal membrane induced by activated macrophages.
abstract: A rabbit model of glial epiretinal membrane was established following the injection of activated macrophages into the vitreous. The membrane was composed entirely of cells with glial characteristics, ie, abundant intermediate filaments, microvilli, junctional complexes and basement membranes. The extracellular matrix of the mature membranes contained collagen fibrils of 10 to 15 and 20 to 25 nm in diameter. Fusiform densities were seen adjacent to the cell membrane and cells with indented nuclei were found in thick membranes. These observations demonstrate that glial cells in epiretinal membranes may synthesize collagen and possess myofibroblast-like properties.
