Repeatability of central corneal thickness measurement with the Pentacam HR system
Purpose: To assess the repeatability of central corneal thickness measurement at the geometrical center (Central Corneal Thickness CCT) given by the Pentacam High Resolution (HR) Comprehensive Eye Scanner (Oculus, Wetzlar, Germany) over time. Methods: Prospective, single center, observational study. Two separate CCT measurements were taken by the Pentacam corneal tomography exam (CTm) 3 to 12 m...
متن کاملHuman corneal thickness using a noncontact specular microscope
The aim of this work was to study the central corneal thickness values and interobserver variability using a noncontact specular microscope. Methods: 62 eyes from 31 healthy subjects were studied with the Topcon SP-2000P noncontact specular microscope (Topcon Corp., Tokyo, Japan). 16 (51.61%) were females, and 15 (48.38%) were males. The mean age of the sample was 31.83±5.68 years. The mean of ...
متن کاملRepeatability and reproducibility of corneal thickness using SOCT Copernicus HR.
PURPOSE The aim of this study is to determine the reliability of corneal thickness measurements derived from SOCT Copernicus HR (Fourier domain OCT). METHODS Thirty healthy eyes of 30 subjects were evaluated. One eye of each patient was chosen randomly. Images were obtained of the central (up to 2.0 mm from the corneal apex) and paracentral (2.0 to 4.0 mm) cornea. We assessed corneal thicknes...
متن کامل[Specular microscopy of the corneal endothelium].
The endothelium of the normal corneas of 67 human subjects was studied in vivo with the specular microscope in order to quantify the method as a means of sampling the cell density of the tissue. It was found that (1) axial cell counts of the endothelium are reproducible in the same cornea after an interval of time; (2) the cell counts of the centre and periphery of the same cornea are similar; ...
متن کاملSpecular microscopy of the corneal endothelium
Although it is possible to observe the individual cells of the corneal endothelium with the use of the biomicroscope and specular illumination (Vogt, 1919), eye movements and the limited magnification available virtually preclude the use of this technique for systematic study of the endothelium. These problems have been largely overcome by the introduction of the specular microscope (Maurice, 1...
