ADHESIVE MECHANISMS OF THE CORNEAL EPITHELIUM
Acta Ophthalmologica, 1992Abstract The corneal epithelium adheres to the stro‐ma through a series of linked structures termed collectively the adhesion complex. These structures include; intermediate filaments (keratin filaments) which are linked to the hemidesmosome; the hemidesmo‐some; the anchoring filaments which extend from the membrane at the hemidesmosome through the ...

Specular Microscopy of Corneal Epithelium
Archives of Ophthalmology, 1983Specular 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.

Angiogenic activity of the corneal epithelium
Experimental Eye Research, 1985A 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.

Corneal Epithelium in Penetrating Keratoplasty
American Journal of Ophthalmology, 1980We 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 ...

Integrins in Human Corneal Epithelium
Cornea, 1991Monoclonal antibodies (Mabs) were used for immunohistochemical location of integrin beta- (beta 1,3, and 4) and alpha subunits (alpha 1-6 and alpha v) in the epithelium of both normal and tissue-cultured human cornea. Immunoreaction for the beta 1 integrin subunit was the most intense at the membranes of the basal epithelial cells and weaker at the ...

Microcystic Dystrophy of Corneal Epithelium
Archives of Ophthalmology, 1966A 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 ...

Corneal epithelium following intraepikeratophakia
Journal of Cataract and Refractive Surgery, 1991The 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 ...

Fc receptors in corneal epithelium
Current Eye Research, 1989The corneal epithelia of the mouse, rabbit and human were shown to contain Fc receptors by an indirect method with immunoglobulins, labelled second antibody and the avidin-biotin peroxidase complex (ABC); and a direct method with the peroxidase conjugated Fc fragment.

Growth Factors and Corneal Epithelium
Cornea, 1988Regeneration 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 ...

The fine structure of the corneal epithelium
Experimental Eye Research, 1962The fine structure of the corneal epithelium has been investigated with particular reference to the intercellular attachment areas or desmosomes. It has been found that the desmosomes vary markedly in structure; those on the basement membrane being different from those between the wing cells, and those between the wing cells again showing differences ...
