Ultrastructure of conjunctival epithelium replacing corneal epithelium

Current Eye Research, 1986
After corneas of mice had been totally denuded of their epithelium by the application of n-heptanol, the new epithelium which grew over the corneas was studied by electron microscopy at intervals up to 7 months. The purpose was to compare the basal attachment of the new cells, derived from conjunctiva, with that of true corneal epithelial cells growing

Angiogenic activity of the corneal epithelium

Experimental Eye Research, 1985
A homogenate of corneal epithelial cells was tested to determine if it could induce vascularization in the cornea. Both fresh and cultured cells were used as sources of the homogenate which was evaluated in vivo using a self-contained system to perfuse it constantly into the corneal stroma.

Image Analysis of the Corneal Epithelium

Ophthalmologica, 2010
The method for quantifying corneal epithelial images has been examined. When pictures were developed, the images were stored in the memory of the image processing system by video camera. The distribution of the density of the images was analyzed. The density of each pixel of an image was assigned one of 256 grades, from completely black to completely ...

Corneal Epithelium in Diabetic Patients

Cornea, 1991
The corneal epithelia of phakic control (n = 13), aphakic control (n = 10), diabetic phakic (n = 10), and diabetic aphakic patients (n = 13) were surveyed under a wide-field specular microscope with a special contact lens. In control patients, the corneal epithelium showed relatively hexagonal cells, which we divided into three groups: bright cells ...

Wettability and wetting of corneal epithelium

Experimental Eye Research, 1971
The wettability of cleansed corneal epithelium by aqueous solutions has been studied. The critical surface tension of corneal epithelium in situ and that of epithelial monolayers cultured from cornea has been determined with pure hydrophobic liquids.

Specular Microscopy of Corneal Epithelium

Archives of Ophthalmology, 1983
Specular microscopy was used to study the morphologic appearance of normal and regenerating rabbit corneal epithelium before and after corneal abrasion or heptanol application. Specular photomicrographs of the denuded area and healing epithelium were taken for two to three weeks as the epithelium regenerated, as well as prior to trauma.

Corneal Epithelium in Penetrating Keratoplasty

American Journal of Ophthalmology, 1980
We studied corneal epithelium in 66 patients with bullous keratopathy treated with penetrating keratoplasty using McCarey-Kaufman stored donor corneas. Epithelium was evaluated at times of storage, surgery, and postoperative dressing changes. Epithelium was intact in 43 of the donor corneas at storage, and 23 had 5 to 100% (median, 50%) epithelium ...

Corneal epithelium following intraepikeratophakia

Journal of Cataract and Refractive Surgery, 1991
The corneal epithelium in eight patients was surveyed by biomicroscopy and specular microscopy before and after the intraepikeratophakia procedure. Autografting of the epithelium was also examined by electron microscopy. Although the superficial layer of the epithelium was damaged, the wing cell layer remained intact, contributing to the ...

Microcystic Dystrophy of Corneal Epithelium

Archives of Ophthalmology, 1966
A new disease of the corneal epithelium called microcystic dystrophy was recently described by Cogan et al. 1 Clinically, this typically exhibits bilateral groups of grayishwhite round or comma-shaped deposits in the corneal epithelium. The disease appears to be more common in women than in men, and has been observed to cause a slight reduction of ...

Growth Factors and Corneal Epithelium

Cornea, 1988
Regeneration of corneal epithelium following injury is essential for visual rehabilitation. A limited number of approaches are available for treating patients who fail to heal epithelial injuries adequately. The presence of specific receptors for epidermal growth factor (EGF) on epithelial cells suggests that this potent mitogen may play a role in ...
