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.

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 [1] using the same wavelength of light as retinal OCT, namely 830nm.

Mar 1, 2020 · AS-OCT is a useful tool for the differentiation between pterygium and CIN able to provide typical morphological characteristics. An EE greater than 141 μm in AS-OCT suggests a sensitivity and specificity of 100% for the diagnosis of CIN.

Dec 13, 2022 · This study aims to systematically review the reported literature on the use of anterior segment optical coherence tomography (AS-OCT) in ocular surface tumours and simulating lesions.

High resolution anterior segment optical coherence tomography (HR-OCT) has revolutionized the way by which clinicians can diagnose and differentiate ocular surface lesions. Careful interpretation of HR-OCT images can provide morphological information about the lesion of interest and help guide the diagnosis.

AS-OCT is a useful tool for the differentiation between pterygium and CIN able to provide typical morphological characteristics. An EE greater than 141μm in AS-OCT suggests a sensitivity and specificity of 100% for the diagnosis of CIN.

Jun 12, 2018 · In this review, we aim to discuss the various applications of anterior segment OCT (AS-OCT) for dystrophic, degenerative, and neoplastic ocular surface and corneal pathologies as well as provide recommendations for routine use of this beneficial technology in the diagnosis and management of these conditions.

Purpose: To report a case of biopsy-proven corneal intraepithelial neoplasia (CIN) diagnosed and followed clinically using high-resolution anterior segment optical coherence tomography (AS-OCT) and in vivo confocal microscopy (IVCM). Methods: Observational case report.

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 …

Anterior segment optical coherence tomography (AS-OCT) has become one of the cornerstones of non-contact imaging modalities for assessing such structures as the cornea, anterior chamber angle, aqueous outflow pathway, sclera, and ocular surface structures.
