HYDROGEN PEROXIDE AND CORNEAL ENDOTHELIUM
Acta Ophthalmologica, 1981Because of recent evidence of low levels of hydrogen peroxide in the aqueous humor, studies were performed to determine levels of corneal endothelial toxicity as well as factors modifying toxicity. Perfusion of cornea endothelial cells for 3 h with varying concentrations of hydrogen peroxide demonstrated a threshold of toxicity at a nominal ...

Corneal endothelium – Specular microscopy
Acta Ophthalmologica, 2022AbstractCorneal endothelium is a single layer of hexagonal cells covering the inner surface of the cornea and maintains the corneal deturgescence by continuous pumping of water and ions from the stroma to the aqueous humour. This mechanism is necessary to preserve the transparency of the cornea. The corneal endothelium is derived from the neural crest.

Gene Delivery to the Corneal Endothelium
American Journal of Respiratory and Critical Care Medicine, 2000Gene transfer to the corneal endothelium has potential for modulating rejection of corneal grafts. It can also serve as a convenient and useful model for gene therapy of other organs. In this article we review the work carried out in our laboratory using both viral and nonviral vectors to obtain gene expression in the cornea.

Macromolecular synthesis in corneal endothelium
Experimental Eye Research, 1971Corneal macromolecular synthesis from intermediates derived from glucose is examined. The kinetics of incorporation into the epithelium and endothelium may be more accourately determined by a quantitative method of radioautography, recently described, than from direct isolation techniques.

Publisher Summary The corneal endothelium, also called “corneal posterior epithelium” is a comparatively thin innermost layer of the cornea. This chapter discusses the shape, function, and transparency of endothelial cells and electrolyte transport by the endothelium. The corneal endothelium is placed directly in the visual pathway.

1979
Clinical specular microscopy has indicated that human cell healing occurs by spreading, there is a limited healing reserve, and premature cell loss is the equivalent of a ‘premature aging’ that may lead to later decompensation. This instrument has been useful in studying healing and cell damage from surgery, drugs, and special procedures such as ...

HISTOCOMPATIBILITY AND CORNEAL GRAFT ENDOTHELIUM
Acta Ophthalmologica, 1979Endothelia of 102 clear human corneal grafts in 95 patients were photographed in vivo with a specular microscope. The relation of the endothelial cell density to the HLA and ABO compatibility of the donor‐recipient pairs were studied. In addition, the effects of vascularization and reversible rejection on the endothelial cell density were analysed.A ...

Photography of the Corneal Endothelium
International Ophthalmology Clinics, 1976Excellent photographs of corneal endothelial cells may be obtained during clinical examinations with the specular microscope. Endothelial photographs are extremely useful in documenting the corneal effects of ocular trauma, aging, inflammation, and surgery.
