Segmentation and Quantification for Angle-Closure Glaucoma Assessment in Anterior Segment OCT [PDF]

IEEE Transactions on Medical Imaging, 2017
Angle-closure glaucoma is a major cause of irreversible visual impairment and can be identified by measuring the anterior chamber angle (ACA) of the eye. The ACA can be viewed clearly through anterior segment optical coherence tomography (AS-OCT), but the imaging characteristics and the shapes and locations of major ocular structures can vary ...

Anterior Segment OCT [PDF]

, 2019
OCT technology has been utilized successfully for anterior segment evaluation, offering several clinically relevant applications. Its capabilities allow for non-contact imaging, detailed visualization and analytics of anterior segment structures of the human eye on one device. These structures include the cornea, anterior chamber, iris, and lens.

Anterior Segment Optical Coherence Tomography (AS-OCT) Visualization of Anterior Vitritis

Ocular Immunology and Inflammation, 2022
The clinical grading of vitreous haze presents some limitations such as subjectivity and intra-grader variability. On the other hand the proposed OCT-based methods only explore the posterior part of the vitreous. Here we describe the inflammatory changes affecting the anterior vitreous imaged by Anterior Segment Optical Coherence, Tomography (AS-OCT ...

Anterior Segment OCT in Glaucoma

2020
Anterior segment optical coherence tomography (AS-OCT) has emerged as an important imaging tool to aid in the diagnosis, treatment, and follow-up of eye conditions. Developed from the same technology used for traditional retinal imaging, AS-OCT provides a view of the anterior chamber structures with a noncontact approach.
