Study on Intraocular Structural Parameters and Surgical Effect Before and After the Onset of Malignant Glaucoma

Outcome Measures: 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.

Inclusion Criteria: (1) history of operation, (2) diagnosis of MG, and (3) eyes with clear optical media. Exclusion Criteria:(1)hypertension or diabetes and (2) diagnosis of ocular fundus diseases.
