A total of 40 eyes from 29 PACD patients and 40 eyes from 34 normal subjects received full ophthalmic examination and CASIA SS-1000 OCTJournal of glaucomaAnterior Segment OCT in Primary Angle Closure Disease Compared With Normal Subjects With Similar Shallow Anterior Chamber.PMC8795465R21 EY028747Ma PYonamine SYang YLi SYing GSHan YXie QPatlidanon JSaifee MYu YfalseAnterior Segment OCT in Primary Angle Closure Disease Compared With Normal Subjects With Similar Shallow Anterior Chamber.<h4>Prcis</h4>Compared with normal subjects with similar shallow anterior chamber depth (ACD), patients with primary angle closure disease (PACD) had narrower angle structures measured by swept-source optical coherence tomography (SS-OCT) at 250 μm from scleral spur (very root of iris), especially along oblique and vertical axis.<h4>Purpose</h4>To examine anterior segment structures in normal subjects whose ACD was shallow on slit-lamp examination but did not meet the diagnostic criteria of PACD, and to compare them with PACD patients with similar ACD.<h4>Materials and methods</h4>Patients were recruited from glaucoma clinic at Zhongshan Ophthalmic Center.
