Comparison 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...
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 کاملComparison of artemis 2 ultrasound and Visante optical coherence tomography corneal thickness profiles.
PURPOSE To compare corneal thickness profiles of cross-sections of cornea determined by arc-scanned immersion ultrasound and optical coherence tomography (OCT). METHODS Corneas of 28 eyes from 14 participants were scanned in triplicate using the Artemis 2 high-frequency arc-scanned ultrasound system (ArcScan Inc) and the Visante OCT system (Carl Zeiss Meditec). Corneal thickness and reproduci...
متن کاملAnterior Segment Tomography with the Cirrus Optical Coherence Tomography
Optical coherence tomography (OCT) is an optical acquisition method to examine biological tissues. In recent years, OCT has become an important imaging technology used in diagnosing and following macular pathologies. Further development enabled application of optical coherence tomography in evaluation of the integrity of the nerve fiber layer, optic nerve cupping, anterior chamber angle, or cor...
متن کاملAnterior segment optical coherence tomography in corneal and conjunctival pathology
METHODS: Retrospective study which included patients examined using AS-OCT (HD-Cirrus) between June and December 2011. e following information was obtained: diagnosis, surgical procedure, AS-OCT image usefulness/quality, biomicroscopy photographs. Cases were classi ed into the following groups: 1. e AS-OCT provided a satisfactory image and provided additional information to that obtained by bio...
