Figure 5. Apoptotic trabecular meshwork cells after 1 mg/ml triamcinolone acetonide treatment. Apoptotic nuclei of TM cells were detected 12 h as well as 1, 3, and 5 days after 1 mg/ml TA treatment. The slide was viewed with two filters. Stain red was viewed using a fluorescein filter to visualize end-labeled cells. Stain blue was viewed with a DAPI filter to visualize the entire cell population. Scale bar: 50 μm.
