Automated corneal endothelial cell analysis
[1992] Proceedings Fifth Annual IEEE Symposium on Computer-Based Medical Systems, 2003Corneal endothelial cell images taken by a noncontact specular microscope usually have a strong gray-scale gradient and flare that make automated analysis very difficult. The development is reported of an automated analysis system of the noncontact specular image, using a specially variant contrast enhancement to remove these obstacles from the ...

The inheritance of corneal endothelial cell density
Ophthalmic Genetics, 2016Although it is known that some corneal diseases and degenerations have a significant heritable background, heritability on corneal endothelial cell density (ECD) has never been clearly determined. Our aim was to determine the heritability of corneal ECD.Corneal ECD of 114 eyes (66 eyes of 33 monozygotic and 48 eyes of 24 dizygotic pairs; mean age 49.0 ±

Photomicrography of Corneal Endothelial Cells in vivo
Nature, 1973WE have described the principles of operation for a microscope designed to examine objects embedded in highly reflecting or scattering biological materials1. We present here the first successful application of this device to the observation of endothelial cells lining the inside of the cornea.

The Effect of Smoking on Corneal Endothelial Cells
Seminars in Ophthalmology, 2015To investigate the effect of chronic cigarette smoking on the endothelial cells of the cornea via non-contact specular microscopy.In this prospective, cross-sectional study, 25 eyes of 25 chronic smokers and 21 eyes of 21 age-matched, healthy non-smokers were enrolled.

Primary cell culture of canine corneal endothelial cells
Veterinary Ophthalmology, 2021AbstractObjectiveTo establish a primary cell culture and clarify the characteristics of canine corneal endothelial cells in vitro.ProceduresThe eyes were enucleated from dogs that were euthanized for reasons unrelated to this study. Enucleated canine eyes were dissected, and the intact corneas were isolated from the globes.

CORNEAL ENDOTHELIAL CELL DENSITY IN IRIDOCYCLITIS
Acta Ophthalmologica, 1979The endothelial cells of both eyes of 60 unilateral iridocyclitic patients were photographed with a specular microscope to establish the possible effect of iridocyclitis on corneal endothelial cells.Chronic severe iridocyclitis with mutton‐fat keratic precipitates (KP) lowered the central endothelial cell count.

Central Corneal Endothelial Cell Counts in Children
American Intra-Ocular Implant Society Journal, 1979Our data indicate that corneal endothelial cell density in a normal eye remains essentially unchanged from ages five to 20. Changes in cell density and morphology during the first five years of life need further investigation. In this study, the mean endothelial cell count of a normal population of children was 2696 cells/mm2.

The Culture of Limbal Stromal Cells and Corneal Endothelial Cells
2013The cornea is the transparent front part of the eye and comprises three distinct cell layers. One of these cell layers is a self-renewing epithelium long believed to harbor a resident stem cell population. The location and characteristics of corneal epithelial stem cells have now been confirmed by several research groups, and these cells are currently ...
