Ultrasound biomicroscopy image showing the measurements of ocular biometric parameters. A The measurements of central anterior chamber depth (ACD), pupil diameter (PD), anterior chamber width (ACW), and lens vault (LV). B The measurements of anterior chamber angle 500 (ACA500), angle opening distance 500 (AOD500). C The measurements of iris thickness at 1000 µm from iris root (IT1000) and iris thickness at 500 µm from iris root (IT500). D The measurements of trabecular meshwork-ciliary process distance (TCPD). E The measurement of scleral–ciliary process angle (SCPA). F The measurement of trabecular meshwork-ciliary process angle (TCPA). G Image of a quadrant depicting basal iris insertion
