About this trial
This is an interventional basic science trial for Open-angle Glaucoma focused on measuring matrix metalloproteinase 13, tissue inhibitor of metalloproteinases 3, calcium-sensing receptor, trabecular meshwork, open-angle glaucoma
Eligibility Criteria
Inclusion Criteria:
- intraocular pressure greater than 22 mmHg with two or more medications
- wide anterior chamber angle
- glaucomatous optic neuropathy (Glaucomatous optic nerve damage was defined as cup-to-disc ratio higher than 0.7 or focal loss of the nerve fiber layer (notch) associated with a consistent glaucomatous visual field defect
- visual field loss consistent with optic nerve damage and visual fields were performed by using standard automated perimetry
Exclusion Criteria:
- the presence of any secondary form of glaucoma including exfoliation syndrome or a history of ocular trauma, etc

5. Study Description
Brief Summary
This study was to assess the distinct expression of matrix metalloproteinase 13,tissue inhibitor of metalloproteinases 3, and calcium-sensing receptor, in human trabecular meshwork between normal and glaucomatous eyes.The expressions of matrix metalloproteinase 13, tissue inhibitor of metalloproteinases 3 and calcium-sensing receptor in the trabecular meshwork tissues were examined by streptavidin-peroxidase immunohistochemical staining method and western blot, and histological changes of trabecular meshwork were studied by Hematoxylin and Eosin staining.
