Risk factors including short axial length, shallow anterior chamber, narrow angles, spherical lens and other characters such as gender, age and family history are well known to be related to the attack of primary angle-closure glaucoma(PACG). In recent years, with the development of advanced techniques such as the anterior segment optical coherence tomography(AS-OCT)and ultrasound biomicroscope(UBM), the technical supports for the measurement of anterior segment parameters were largely provided, which made it possible to quantify risk factors of PACG precisely. In this paper, the relevant research progresses of commonly used anatomic parameters and their significances in pathogenesis of PACG were reviewed.
