Corneal epithelial wound healing in partial limbal deficiency.
Previous studies have shown that the corneal epithelial stem cells are located at the limbal basal layer. The limbal stem cells are regarded as the ultimate source for corneal epithelial cell proliferation and differentiation. This paper examines epithelial wound healing in rabbit corneas with partial limbal deficiency (PLD), which was created by the surgical removal of two-thirds of the limbal...
متن کاملComparison of Ultra Structure and Gene Expression of Cultured Limbal Stem Cells and Fresh Conjunctival, Limbal and Corneal Tissues
Purpose: The present study intends to show the characteristics of cultured limbal stem cell (CLSCs) and to compare them with normal Conjunctival (C), Limbal (L) and Cornea (K) tissues. Materials and Methods: The expressions of a set of genes potentially involved in differentiation and stemness function of limbal stem cells were assessed in freshly prepared limbal, corneal, and conjunctival tis...
متن کاملConjunctival epithelium in healing of corneal epithelial wounds.
The mitotic rate and goblet cell content of conjunctival epithelium following total or central corneal epithelial removal using n-heptanol was measured to determine how the conjunctival epithelium responds to injury and whether conjuctiva responds to central corneal epithelial loss. One day following a wound that removed corneal, limbal, and 1-2 mm of bulbar conjunctival epithelium, the mitotic...
متن کاملCorneal topographic changes in a case of limbal conjunctival carcinoma.
PURPOSE To describe topographic changes in a case of limbal conjunctival carcinoma. METHODS Corneal topography was performed before and 3 months after excision. RESULTS Preoperative topography revealed a localized flattening (37.1 diopters [D]) adjacent to the tumor and extending to the corneal apex, causing a 3-diopter asymmetric with-the-rule astigmatism. Preoperative corneal curvature wa...
متن کاملUnilateral Conjunctival-Corneal Argyrosis Simulating Conjunctival Melanoma
clinically misdiagnosed as choroidal melanoma. Currently, most subretinal tumors assumed to be choroidal melanomas are treated with radiotherapy without histological confirmation. The diagnosis of an RPE carcinoma may therefore be missed. Finger et al described a darkly pigmented subretinal tumor accompanied by inflammation that was suspected of being an adenocarcinoma of the RPE. In several pu...
