Excessive proliferation of corneal epithelium.
SIRs,-I was interested to read in the September issue the description by Dr. G. S. Sihota (Brit. J. Ophthal., 1965, 49, 497) of a soldier's eye which showed massive fibrinous exudate on the conjunctiva and corneal epithelium. The facts that direct smear and culture from the conjunctival sac were negative for pathogenic organisms, and that in spite of recurrent membrane-like growths on the conju...
متن کاملApoptosis in the corneal epithelium.
PURPOSE To determine the viability of corneal surface cells and to determine whether apoptosis is present in the corneal epithelium of the rabbit. METHODS The viability of epithelial surface cells was examined using a calcein-ethidium assay. In this two-color fluorescence assay, viable cells fluoresce green, and the nuclei of nonviable cells fluoresce red. The number of nonviable cells on the...
متن کاملTransplant of corneal epithelium to rabbit corneal wounds in vivo.
Sheets of corneal epithelium removed from 9-mm buttons of adult rabbit corneas using Dispase II were placed on abraded (basement membrane intact) or keratectomized corneas of anesthetized rabbits. Both types of wounds extended from limbus to limbus. The host animals were maintained under deep anesthesia for 3 hr, during which time culture medium was dripped onto the surface of the transplant. A...
متن کاملAn investigation into corneal enzymatic resistance following epithelium-off and epithelium-on corneal cross-linking protocols
The aim of this study was to investigate corneal enzymatic resistance following epithelium off and on riboflavin/UVA cross-linking (CXL). One hundred and fourteen porcine eyes were divided into four non-irradiated control groups and seven CXL groups. The latter comprised; (i) epithelium-off, 0.1% iso-osmolar riboflavin, 9 mW UVA irradiation for 10 min, (ii) disrupted epithelium, 0.1% hypo-osmol...
متن کاملReactive keratoma of the central corneal epithelium.
PURPOSE The authors present a unique corneal tumor. METHODS A 75-year-old gardener presented with a 1-year history of a slowly growing central corneal lesion with progressive visual loss. We performed an ophthalmic examination, slit lamp photography, high-frequency ultrasonography, and culture with sensitivity (followed by therapeutic scrape biopsy). RESULTS Clinical examination revealed a ...
