Corneal endothelium and growth factors

Survey of Ophthalmology, 1996
Human corneal endothelium is characterized by a low regenerative capacity, mainly because of a low mitotic activity, and therefore complete regeneration of the endothelial layer after injury is precluded. A decrease in endothelial cell density and an abnormal cell mosaic, which may occur after many conditions, can compromise the integrity of the ...

Ultraviolet-B Damages Corneal Endothelium

Optometry and Vision Science, 1984
Direct in vivo observation of acute ultraviolet (UV)-induced corneal endothelial damage is not possible due to the more severe damage produced in the epithelium. In order to quantify damage and evaluate endothelial recovery an indirect method was used.

Corneal Endothelium in Herpetic Keratouveitis

Archives of Ophthalmology, 1983
The corneal endothelium underwent changes in 15 patients with unilateral herpetic keratouveitis. Study with both noncontact and wide-field specular microscopes showed that six patients had mild and nine patients severe keratouveitis. Transient endothelial changes indicating endotheliitis were observed in all eyes affected by severe keratouveitis.

Ionic transport across corneal endothelium

Acta Ophthalmologica, 1985
Abstract. The active potential difference across bovine corneal endothelium was measured in vitro at different temperatures, pH, osmolality and salt compositions. The measurements were made using either identical or different solutions on each side of the membrane.

Morphogenesis of rabbit corneal endothelium

Current Eye Research, 1988
We studied ultrastructurally the development of rabbit corneal endothelium from the 13th day of gestation to 3 days after birth. Precursor corneal endothelial cells, stromal cells, and a vascular network migrate in close association with each other between the developing corneal and lens epithelia.

Corneal endothelium after refractive surgery

Journal of Cataract and Refractive Surgery, 2011
The endothelium is vital to the health and optical clarity of the human cornea. The safety of procedures to correct refractive errors depends on preservation of an intact corneal endothelium. Disease states and genetic and environmental factors affect the corneal endothelium; an unstable corneal endothelium can impact the success of refractive surgery.

HYDROGEN PEROXIDE AND CORNEAL ENDOTHELIUM

Acta Ophthalmologica, 1981
Because 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, 2022
AbstractCorneal 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, 2000
Gene 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, 1971
Corneal 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.
