Retrocorneal fibrous membrane in the vitreous touch syndrome.
The retrocorneal fibrous membrane in eight cases of the vitreous touch syndrome was characterized by homogeneous granular material, fine filaments arranged either singly or in bundles, multiple lamellae of basement membrane-like material, and banded figures of similar to 110 nm periodicity. Seven cases demonstrated an intact endothelial monolayer while only one showed cells in a markedly thickened fibrous layer. These findings support the pathogenic mechanism of endothelial fibrous metaplasia and secretory activity as the origin of the retrocorneal fibrous membrane in the vitreous touch syndrome.
