Anterior 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 کاملEffects of diurnal, lighting, and angle-of-incidence variation on anterior segment optical coherence tomography (AS-OCT) angle metrics
BACKGROUND First reported study to assess the effect of diurnal variation on anterior chamber angle measurements, as well as, to re-test the effects of lighting and angle-of-incidence variation on anterior chamber angle (ACA) measurements acquired by time-domain anterior segment optical coherence tomography (AS-OCT). METHODS A total of 30 eyes from 15 healthy, normal subjects underwent anteri...
متن کاملReproducibility of anterior chamber angle measurements with anterior segment optical coherence tomography.
PURPOSE To study the reproducibility and variability of iridocorneal angle (ICA) measurements by using anterior segment optical coherence tomography (AS-OCT) by expert and nonexpert observers. METHODS Twenty-three healthy volunteers (nonexperts with a basic knowledge of ophthalmology) acquired five consecutive AS-OCT images in the enhanced anterior segment single mode in the 180° to 0° meridi...
متن کاملAnterior segment optical coherence tomography in acute anterior uveitis.
PURPOSE To analyze the corneal thickness and anterior chamber (AC) angle using anterior segment optical coherence tomography (AS-OCT) in patients with acute anterior uveitis (AAU). METHODS Twenty two patients (24 eyes) were included. All patients underwent complete ophthalmological examination, applanation tonometry and AS-OCT at diagnosis and fifteen days after treatment. RESULTS Average c...
