Donor cell density and endothelial keratoplasty
British Journal of Ophthalmology, 2010We read with interest the recent article by Amato et al , ‘Pre-cut donor tissue for Descemet stripping automated keratoplasty: anterior hinged lamella on versus off’.1 We congratulate Dr Amato and his colleagues for their contribution to the rapidly changing field of endothelial keratoplasty (EK).

Corneal endothelial cell density in patients receiving chemotherapy
Cutaneous and Ocular Toxicology, 2021This study aimed to determine if the corneal endothelium was affected by chemotherapy.Chemotherapy patients were recruited to undergo specular microscopy before treatment and again at 1- and 2-year follow-up visits. One eye per patient, per follow-up, was selected for comparison to baseline.Forty-six volunteers completed baseline and at least one ...

Staining of endothelial cells does not change the result of cell density
Cell and Tissue Banking, 2019To determine the corneal endothelial cell density human donor corneas are usually placed in hypotonic balanced salt solution for unstained cell counting. Experimental studies often stain the corneal endothelium to highlight cells and cell borders and simplify counting. However, staining normally terminates the experiments.

Precision of Cell Density Estimates and Endothelial Cell Loss With Age
Archives of Ophthalmology, 1985The precision of estimating endothelial cell density of the cornea, using a noncontact method of specular microscopy, was assessed by asking eight individuals with known densities in one operated-on and one unoperated-on eye to have photography on two occasions in the same day.

Atherosclerosis, 1987
Smooth muscle cells (SMC) cultured in the presence of endothelial cells (EC), or in EC-conditioned medium, show increased synthesis of glycosaminoglycans (GAG). We have found that both the amount and type of GAG produced by the SMC are dependent on the density of the EC. EC (porcine) at a low density (0.1-0.5 X 10(6) cells/25 cm2), or their conditioned

Ophthalmology, 1999
To determine when corneal transplants develop the decreased endothelial cell density that predisposes to late endothelial failure (LEF).Noted cohort study within a prospective case series.The authors compared 21 grafts that developed LEF with the remaining transplants (controls) in a longitudinal cohort study of 500 consecutive penetrating ...

Pterygium Is Related to a Decrease in Corneal Endothelial Cell Density
Cornea, 2014The aim of this study was to investigate the relationship between pterygium and a decrease in the corneal endothelial cell density (ECD) in patients with unilateral primary pterygium.In this retrospective cross-sectional study, 90 consecutive patients with unilateral primary pterygium were enrolled from January 2010 to June 2012.

INDIRECT EVALUATION OF CORNEAL ENDOTHELIAL CELL DENSITY
Acta Ophthalmologica, 1978In 16 whole flat corneal mounts stained by alizarine red and trypane blue it was investigated whether estimates of central numerical endothelial cell density could be based on peripheral cell density, on age or on morphological cell characteristics. With certain precautions estimates of central cell density could be based on peripheral cell density, on

Factors influencing endothelial cell density of corneas for transplantation
Cell and Tissue Banking, 2020To evaluate factors affecting corneal endothelial cell density (ECD) under enucleation and preservation time studies at Eye Bank of the Federal District of Brazil. We conducted a case-control study collecting data from 1128 corneas where death-to-enucleation time and enucleation-to-preservation time were within 24 h.

Corneal endothelial cell density and morphology in patients with acromegaly
Growth Hormone & IGF Research, 2014Acromegaly has various impacts on many organs. The ophthalmologic effects of acromegaly have not yet been investigated in detail. The aim of the current study was to evaluate qualitative and quantitative changes in corneal endothelial cells and central corneal thickness (CCT) of the patients with acromegaly.In this prospective, cross-sectional study ...
