Optical coherence tomography (OCT) is a high resolution cross-sectional imaging modality initially developed for retinal imaging. Anterior segment OCT (ASOCT) imaging was first described in 1994 by Izatt et al using the same wavelength of light as retinal OCT, namely 830nm. This wavelength is suboptimal for imaging the angle due to limited ...

Anterior segment OCT (AS-OCT) facilitates obtaining an “optical biopsy” or in vivo imaging of various dystrophic, degenerative, and neoplastic ocular surface and corneal pathologies, allowing clinicians to diagnose diseases otherwise not visualized by traditional methods. [2] How does AS-OCT work and what machine options are available?

2023年1月15日 · AS-OCT is an invaluable patient education and monitoring tool to follow the resolution of edema over time. AS-OCT has significant functionality when used preoperatively or intraoperatively for corneal procedures targeted at specific corneal layers, including epithelial debridement, superficial keratectomy and phototherapeutic keratectomy.

2022年7月1日 · Anterior segment optical coherence tomography (AS-OCT) constitutes an important imaging modality to examine the anterior eye, which is commonly used in research and clinical practice. Since its introduction, a range of image analysis methods have been developed to quantify these images using different analysis techniques for various applications.

Anterior segment optical coherence tomography (AS-OCT) imaging is a non-contact imaging technique that produces high-resolution images and quantitative measurements of the anterior segment and its anatomical structures.

2018年4月8日 · Optical coherence tomography (OCT) technology has increased clinical applications in cornea and anterior segment imaging. Ultra-high resolution anterior segment OCT may provide in vivo ‘histology’ images of the cornea with greater detail. OCT enables better understanding of glaucoma mechanisms via imaging of the aqueous outflow system and angles.

Anterior segment optical coherence tomography (ASOCT) is an imaging modality that provides both quantitative and qualitative information on the cornea, anterior chamber angle, iris and crystalline lens. ASOCT shows excellent repeatability and reproducibility for the measurement of corneal thickness, anterior chamber angle and anterior chamber ...

眼前节相干光断层扫描(anterior－segment optical coherence tomography，AS－OCT)是一种无创、非接触式的影像学检查手段，能为眼前节的解剖结构提供多个客观量化指标，与传统的青光眼检查手段相比具有独特的优势，以往已有文献介绍了AS－OCT在青光眼领域的应用概况 ...

Anterior segment optical coherence tomography (AS-OCT) is a non-contact imaging technique that produces high-resolution images and quantitative measurements of the anterior segment and its anatomical structures. There has been rapid development of OCT technology over the past 2 decades, with the tra …

2020年7月25日 · Anterior segment optical coherence tomography (AS-OCT) is a noncontact in vivo imaging method that provides qualitative and quantitative assessments of the anterior segment and its anatomical structures, including the …
