Sponsor's own description
In this retrospective observational study, we collected intraocular structure parameters of malignant glaucoma and primary angle closure glaucoma. Anterior chamber depth (ACD) and width (ACW), lens vault (LV), ciliary process-ciliary process distance(CCD), trabecular-ciliary processes distance (TCPD), ciliary body max thickness (CBMT), peripheral iris thickness (PIT), trabecular ciliary process angle (TCPA), and anterior vault (AV), were measured by ultrasound biomicroscopy. Other parameters measured by A-scan ultrasonography and optical coherence tomography. To analyze the high risk factors and the possible pathogenesis of the disease and discuss the long-term effect of different treatment methods.
