Abstract: The ideal screening methods for primary angle-closure glaucoma (PACG) should be simple, quick, noninvasive and easy-to-perform that aims to quantify the anterior chamber angle. Some methods have been proposed, such as the oblique flashlight test, A-scan ultrasound, van Herick test, gonioscopy, ultrasound biomicroscopy, anterior segment optical coherence tomography, scanning peripheral anterior chamber depth analyzer and Scheimpflug photography although each of them has their advantages and disadvantages. In clinical practice, one may choose a method most appropriate or consider combining two or more methods in order to improve the sensitivity and specificity of screening.
