Ultrastructure of epiretinal membranes causing macular pucker after retinal re-attachment surgery.
The ultrastructural features of the cellular components of surgically obtained preretinal membrane in twelve cases of macular pucker which followed retinal re-attachment surgery have been analysed. A mixture of different types of cells was observed. Definite (7) or probable (1) fibrous astrocytes were present in eight cases. Definite retinal pigment epithelium was the principal cell in only two cases, and four additional cases showed probable retinal pigment epithelium. Fibrocytes and macrophages were present in five cases and blood vessels in two. Nine of the twelve specimens included internal limiting membrane of the retina.
