Anterior 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...
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...
متن کاملAnterior Segment Optical Coherence Tomography: Assisted Topographic Corneal Epithelial Thickness Distribution Imaging of a Keratoconus Patient
PURPOSE To evaluate safety, efficacy and ease of measurement of epithelial thickness in a keratoconic patient based on anterior segment optical coherence tomography (AS-OCT). METHODS A 25-year-old male patient, previously diagnosed with keratoconus, with highly asymmetric manifestation among the two eyes, was subjected to AS-OCT corneal epithelial imaging. We investigated epithelial thickness...
متن کاملAnterior Segment Time Domain Optical Coherence Tomography
To compare anterior segment parameters using quantitative imaging by anterior segment time domain optical coherence tomography (AS-OCT) and high frequency ultrasound biomicroscopy (HF-UBM). SETTING: Department of Ophthalmology at Bari University. METHODS: Seventy-two eyes of 72 subjects had anterior segment evaluation by AS-OCT (Stratus ver 6Zeiss) and HF-UBM (OTI-Scan HF35-50). Central corneal...
متن کامل[Anterior segment optical coherence tomography in glaucoma].
In recent years, the rapid development of diagnostic optic devices has generated optical coherence tomography (OCT) as a new, non-invasive diagnostic method. With technical progress of the infrared spectrum at 1,310 nm, OCT of the anterior segment also became feasible. With anterior segment OCT different examinations which so far were ruled out by ultrasound in contact manner could be executed ...
