“…Although it has been reported that Chinese ethnicity is a major risk factor for angle closure, they did not find any association between LV and race . Further studies reported that LV is highly significant in fellow eyes of APAC when comparing with PACG and PACS eyes and it is also a powerful parameter to differentiate phacomorphic angle closure from eyes with mature cataract from APAC eyes …”

This article aims to review the published literature pertaining to the use of anterior segment optical coherence tomography (AS-OCT) in the evaluation of angle-closure disease. Searches on the available published literature were last conducted on 15 June 2017. Rated as Level I evidence, we found that AS-OCT has shown good sensitivity and moderate diagnostic accuracy to detect narrow angles when compared with gonioscopy. AS-OCT quantitative and qualitative parameters demonstrated strong association with the presence of gonioscopically closed angles. This technology provides an objective non-contact method of assessing the angle that is well tolerated by the patient and correlates well with the information provided by gonioscopy.

“…Multiple studies have identified risk factors of APAC on AS optical coherence tomography (AS-OCT), which includes greater lens vault, smaller iris curvature, shallower anterior chamber depth and anterior chamber width 8 22 23. In the current study, we did not perform AS-OCT on all our APAC cases.…”

“…Nevertheless, it cannot provide sufficient information about the ACA or act as a substitute for gonioscopy. Improvement of As-OCT imaging for the ACA, trabecular meshwork, Schlemm's canal, and filtering bleb and tube [16][17][18][19] may promote the diagnostic accuracy and identification of better parameters in the evaluation of the risks for primary angle closure.…”

Background: The aim of this work was to evaluate the narrow anterior chamber angle (ACA) in Chinese patients by anterior segment optical coherence tomography (As-OCT). Methods: Eighty right eyes of 80 consecutive patients with a shallow peripheral anterior chamber but no peripheral anterior synechia were enrolled in this study. The ACA was observed by noncompression gonioscopy and classified according to the Shaffer grading system. The iridotrabecular contact (ITC) and trabecular-iris angle (T-I angle) were assessed by As-OCT examination. Results: Gonioscopic grade 0 and ITC were observed more frequently in the superior quadrant than the other quadrants (p < 0.02). The T-I angle was signiﬁcantly smaller superiorly and inferiorly than nasally and temporally (p < 0.01). The frequency of the ITC and T-I angle significantly declined when the gonioscopic grade was from 0 to 2 (p < 0.01). Logistic analysis showed that the axial length and refraction were related to the presence of ITC in more than two quadrants (p < 0.03). Conclusions: ITC was common in eyes with a shallow peripheral anterior chamber (superiorly, gonioscopic grade 0). Sites with wider gonioscopic grading tended to have a larger T-I angle. Axial length and refraction significantly impacted on the frequency of ITC.
