Objective quantification of corneal haziness using anterior segment optical coherence tomography
Purpose To quantify normal corneal transparency by anterior segment optical coherence tomography (AS-OCT) by measuring the average pixel intensity. To analyze the variation in the average pixel intensity in mild and severe grades of corneal opacities. Methods This is an observational, cross-sectional study of 38 eyes from 19 patients with mild or severe grades of corneal opacities greater tha...
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...
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 ...
متن کاملChange of Optical Intensity during Healing Process of Corneal Wound on Anterior Segment Optical Coherence Tomography
The purpose of this study is to investigate the process of corneal wound healing after penetrating injury with the change in optical intensity on anterior segment optical coherence tomography (AS-OCT) and to investigate factors associated with severity of corneal scar. Forty-seven eyes from 47 patients with repaired corneal laceration were included. AS-OCT was performed on 1day, 1week, 1, 3 and...
