OBJECTIVE: To investigate apoptosis of bovine trabecular meshwork cells induced by dexamethasone. METHODS: In the incubation method of system in vitro, dexamethasone (1-500 mg/L) was added to the syncretic culture solution of third to fifth generation of bovine trabecular meshwork cells. After one to 14 days, the culture solution was observed by phase-contrast microscopy, fluorescence microscopy and transmission electron microscopy, and was studied by DNA laddering and flow cytometric analysis. RESULTS: Dexamethasone (125-500 mg/L) induced apoptosis of trabecular meshwork cells in a dose-time-dependent manner. CONCLUSIONS: Apoptosis of cultured bovine trabecular meshwork cells can be induced by dexamethasone, which may be one of the pathogenic mechanisms of steroid-induced glaucoma. LA: Chinese
