Effect of ageing on keratoconic corneas
PURPOSE To explore the potential effect of ageing on the corneal curvature and corrected visual acuity in patients with long-term keratoconus because of the paucity of these patients older than 50 years. METHODS Records of keratoconic patients, who had initially presented to a specialized contact lens clinic and followed for more than 20 years after disease onset, were reviewed. Collected inf...
متن کاملkeratocyte density in normal and keratoconic corneas using confoscan
purpose: to compare keratocyte density between normal and keratoconic corneas in non-contact lens wearers. methods: confocal scanning was performed on 39 corneas of 26 patients with keratoconus and 28 corneas of 14 normal control subjects. none of the cases were contact lens wearer. all individuals underwent ophthalmic examination and computed topography in addition to confocal microscopy. main...
متن کامل[Abnormal distribution of trace elements in keratoconic corneas].
UNLABELLED Our understanding of etiology and pathogenesis of many disorders, corneal included, greatly relies on existing knowledge in human biochemistry and biophysics. This study was aimed at chemical mapping of normal and keratoconic corneas. MATERIAL AND METHODS Modern methods of analytical chemistry, such as X-ray fluorescence and energy-dispersive X-ray spectroscopy on the basis of scan...
متن کاملTransepithelial corneal collagen cross-linking in ultrathin keratoconic corneas
BACKGROUND The purpose of this paper was to report the results of transepithelial corneal collagen cross-linking (CXL) with modified riboflavin and ultraviolet A irradiation in patients affected by keratoconus, each with thinnest pachymetry values of less than 400 μm (with epithelium) and not treatable using standard de-epithelialization techniques. METHODS Sixteen patients affected by progre...
متن کاملIn vitro incorporation of proline into keratoconic human corneas.
Corneal buttons were obtained from four young adults with advanced keratoconus following perforating keratoplasty. The corneal buttons were incubated in organ culture media containing 3H-proline. Autoradiographs of corneal sections showed that the incorporation of the radioisotope was significantly higher in all layers of the kerotoconic corneas than that found in the normal controls, indicatin...
