title: [Imaging of the iridocorneal angle in glaucoma].
abstract: Iridocorneal angle assessment is essential in glaucoma diagnosis and management, and gonioscopy remains the clinical reference standard for its evaluation. However, performance and interpretation of gonioscopy requires experience and has several limitations. Ultrasound biomicroscopy (UBM) and more recently anterior segment OCT (AS-OCT) and Scheimpflug camera have contributed to a better understanding of the mechanisms of angle-closure, screening of patients at risk for angle-closure glaucoma, and understanding of angle structures in secondary open angle glaucomas. Rapid and non-contact, AS-OCT has made this analysis easier than with UBM, but it is limited by its weak penetration through iris and scleral tissues.
