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 کاملComparison of Scheimpflug imaging parameters between steep and keratoconic corneas of Caucasian eyes
PURPOSE To compare the keratometric and pachymetric parameters of healthy eyes with those affected by steep cornea and keratoconus (KC) using Scheimpflug camera. SETTING Briz-L Eye Clinic, Baku, Azerbaijan. DESIGN A cross-sectional study. METHODS In this study, 49 KC (Amsler-Krumeich stage 1) eyes and 36 healthy eyes were enrolled. A complete ophthalmic evaluation and a Scheimpflug camera...
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 کاملUnderstanding the Correlation between Tomographic and Biomechanical Severity of Keratoconic Corneas
Purpose. To evaluate correlation between tomographic gradation of keratoconus (KC) and its corresponding air-puff induced biomechanical response. Methods. Corneal tomography and biomechanics were measured with Scheimpflug imaging in 44 normal and 92 KC corneas. Deformation waveform was also analyzed with Fourier series. A custom KC severity scale was used from 1 to 3 with 3 as the most severe g...
