Summary
Simple epiretinal membranes are delicate cellular membranes occurring at the vitreoretinal juncture. They produce no symptoms or macroscopically detectable change, but are a common microscopic finding in enucleated eyes. The ultrastructural features of these membranes were studies in eight eyes surgically enucleated for unrelated ocular conditions or for orbital lesions. Simple epiretinal membranes are composed exclusively of glial cells. Evidence is presented that these cells derive from accessory glia of the superficial retina which react to a variety of stimuli and migrate through breaks in the retinal surface (which may later heal). This pathogenic sequence is discussed in light of present knowledge of retinal accessory glia and their role in retinal disease.
