Width and Pigmentation of the Angle of the Anterior Chamber

Assessment of narrow angles by gonioscopy, Van Herick method and anterior segment optical coherence tomography

“…The different anatomical landmarks and levels of irido-angle contact determined to be closed angle on gonioscopy and AS-OCT may contribute to this discrepancy [27,28]. We also agree with previous suggestions that inadvertent pressure and subsequent distortions of the cornea by a gonioscopic lens may change the AC configuration and contribute to poor agreement between gonioscopy and AS-OCT [19,20].…”

Evaluation of Scanning Protocols for Imaging the Anterior Chamber Angle With Anterior Segment-Optical Coherence Tomography

“…The high sensitivity of the vertical scan on AS-OCT reflects our previous finding that, in this cohort, the superior followed by inferior quadrant were the most likely to be closed on gonioscopy. 8 Similar observations with regard to the rates of angle closure in the superior quadrant have been made by other authors using gonioscopy 6,9 and ultrasound biomicroscopy. 10 We found it interesting that the protocol with the best diagnostic performance required only a single scan of the inferior quadrant, and this finding was consistent regardless of the criteria used to define angle closure.…”

Artificial Intelligence in Anterior Chamber Evaluation: A Systematic Review and Meta-Analysis

“…One study mentioned that a senior professor performed the exam but did not provide further details on the exact criteria of classification 23 . In 2 studies, angles were classified using Scheie and Shaffer’s modified classification system, in which the angle is defined as closed if the posterior trabecular meshwork is not visible for at least 180°, or grade 0–1 18,22,24 …”
