简要总结
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.

结局指标
主要结局
Choroidal vascularity parameter
时间窗: baseline
Choroidal vascularity parameter is a vessel ratio measured by optical coherence tomographic images
Trabecular ciliary process angle
时间窗: baseline
TCPA is measured with its apex at the scleral spur, one arm along the posterior corneal surface, and another arm along the most anterior surface of the ciliary body
