Differences in Central Corneal Thickness between Spectral Domain-Optical Coherence Tomography and Ultrasound Pachymetry in Patients with Dry Eye Disease
Purpose. To compare central corneal thickness (CCT) values via Spectral Domain-Optical Coherence Tomography (SD-OCT) and ultrasonic pachymetry in patients with severe dry eye disease (DED) to determine the level of agreement between these 2 methods. Methods. The paired samples t-test was used to compare CCT values in severe DED patients. Matching analysis between methods was performed using int...
متن کاملComparison of optical coherence reflectometry and ultrasound central corneal pachymetry.
In 50 eyes of 25 patients we prospectively measured the central corneal thickness (CCT) comparing the OLCR (Optical Low Coherence Reflectometry) pachymeter with the contact ultrasound pachymeter. The OLCR system was mounted on to a Haag-Streit slit lamp. Every single measurement was the result of 5 scans. With the contact ultrasound Sonomed pachymeter we performed 5 separate measurements and ca...
متن کاملComparison of central corneal thickness measurements using optical low-coherence reflectometry, Fourier domain optical coherence tomography, and Scheimpflug camera.
PURPOSE To compare the results of central corneal thickness (CCT) measurements obtained using optical low-coherence reflectometry (OLCR), Fourier domain optical coherence tomography (FD-OCT), and a Scheimpflug camera (SC), combined with Placido corneal topography. METHODS A total of 25 healthy subjects were enrolled in the present study, and one eye of each subject was included. A detailed op...
متن کاملCentral corneal thickness measurements with optical coherence tomography and ultrasound pachymetry in healthy subjects and in patients after photorefractive keratectomy.
PURPOSE To compare central corneal thickness measurements made using two different methods, optical coherence tomography (OCT) and ultrasound pachymetry, applied both in normal eyes and in eyes on which photorefractive keratectomy (PRK) had been performed. A second objective was to assess the intrasession variability of OCT measurements. METHODS In this prospective study, central corneal thic...
متن کاملComparison of central corneal thickness measured with anterior segment optical coherence tomography versus ultrasonic pachymetry.
PURPOSE To compare central corneal thickness measured with anterior segment optical coherence tomography (AS-OCT) and ultrasonic pachymetry (UP). METHOD A prospective, observational and cross-sectional study was performed. The central corneal thickness was measured in 112 eyes of 112 consecutive patients with AS-OCT and UP. All examinations were performed by the same examiner. The measurement...
