An electron microscopic study of the epiretinal membrane of human eyes
Abstract:
An electron microscopic study was conducted to elucidate the cell types involved in the formation of epiretinal membranes in four cases. In three cases, the specimens were provided by a vitrectomy and pigment epithelial cells (two cases) and fibrocytes (one case) represented the preponderant constituents of the membrane, whereas the membrane consisted chiefly of glial cells in the fourth case in which an eye showing this condition was obtained by enucleation.
Insights
Electron microscopy revealed diverse cell origins in epiretinal membranes. Pigment epithelial cells and fibrocytes predominated in vitrectomy specimens, while glial cells were primary in an enucleated eye.
Area of Science:
- Ophthalmology
- Cell Biology
- Histopathology
Background:
- Epiretinal membranes (ERMs) are a significant cause of visual impairment.
- Understanding the cellular composition of ERMs is crucial for developing targeted therapies.
