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.

Corneal Edema and the Endothelium in Spaceflight
Aerospace Medicine and Human PerformanceINTRODUCTION: With future manned missions that extend beyond low Earth orbit, it would be wise to anticipate all risks to astronaut health, including those relevant to ophthalmology and the ocular surface. Corneal edema has been documented among mice experiments conducted onboard the Space Transportation System mission, STS-133, owing to increased ...

Evaluation and protection of corneal endothelium
American Intra-Ocular Implant Society Journal, 1980A series of experiments was performed in vitro, on animal and human corneas, and in vivo, on monkeys and rabbits, to test the efficacy of various substances which may be used as coatings for intraocular lenses to protect the corneal endothelium from damage. The vital dye, acid violet 49, was applied to evaluate endothelial cell function and damage. Our

Morphogenesis of rabbit corneal endothelium
Current Eye Research, 1988We 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.

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 ...

Preservation of Corneal Endothelium by Freezing
Nature, 1956THE report1 that spermatozoa from several species could be protected from the harmful effects of freezing by the addition of glycerol to the medium opened the way to the preservation for indefinite periods of a wide variety of mammalian tissues. An attempt to include the human cornea in this list2 was only partially successful.

Regeneration of the Human Corneal Endothelium
1981The ability of the human corneal endothelium to regenerate is studied with the scanning electron microscope through examples of corneal diseases and penetrating keratoplasties. This study does not lead to final conclusions on the possibilities of regeneration of the human corneal endothelium but allows us to say that: --regeneration occurs through size

Morphometry of Corneal Endothelium in Patients with Corneal Guttata
Ophthalmology, 2007To study the morphology of the corneal endothelium in patients diagnosed with corneal guttata using an image processing algorithm based on a contour detection method.Retrospective observational case series.Twenty-four subjects with known corneal guttata.Two hundred eight images of corneal endothelium, captured with a noncontact specular microscope were

Vital Staining of Corneal Endothelium
Cornea, 1985The efficacy and applicability of dual vital staining of human and porcine corneal endothelium with trypan blue and alizarin red S stains was investigated. Exposure of endothelial cells to different concentrations of these two dyes for varying periods of time revealed that 0.3% solution of trypan blue for 1 minute followed by 0.2% solution of alizarin ...

Intracameral Thrombin and the Corneal Endothelium
American Journal of Ophthalmology, 1988We perfused the endothelia of isolated human corneas mounted in the specular microscope with BSS Plus containing 1,000-U/ml or 100-U/ml dilutions of two commercially available topical thrombin preparations. Corneas perfused with thrombin at 1,000 U/ml showed intracellular and intercellular vacuole formation and altered junctional complexes.
