Automatic segmentation of anterior segment optical coherence tomography images.
Optical coherence tomography (OCT) images can provide quantitative measurements of the eye's entire anterior segment. A new technique founded on a newly proposed level set-based shape prior segmentation model has been developed for automatic segmentation of the cornea's anterior and posterior boundaries. This technique comprises three major steps: removal of regions containing irrelevant struct...
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 کاملQualitative evaluation of anterior segment in angle closure disease using anterior segment optical coherence tomography
PURPOSE To evaluate different mechanisms of primary angle closure (PAC) and to quantify anterior chamber (AC) parameters in different subtypes of angle closure disease using anterior segment optical coherence tomography (AS-OCT). METHODS In this prospective study, 115 eyes of 115 patients with angle closure disease were included and categorized into three groups: 1) fellow eyes of acute angle...
متن کاملAnterior Chamber Angle Evaluation with Fourier-Domain Optical Coherence Tomography
New advances in anterior segment optical coherence tomography (OCT) technology development allow visualizing the anterior chamber angle of the eye with high speed and high resolution. Fourier-domain (FD) OCT instruments working at 840 nm can reliably identify fine angle structures such as the Schwalbe's line. This paper demonstrates quantitative angle assessment with 840 nm FD-OCT and provides ...
متن کاملMeasurement of Anterior Chamber Angle with Optical Coherence Tomography
Evaluation of the width of the anterior chamber angle and its inlet during the ophthalmic examination is essential in determining the susceptibility of the angle to closure (KalevLandoy et al 2007, Leung et al 2007, Leung et al 2008, Radhakrishnan et al 2005). There are factors that have been recognized as affecting the anterior chamber angle width include age, race/ethnicity, iris color, eye d...
