Figure 6. Apoptosis percentage of the trabecular meshwork cells by 0.1 mg/ml and 1 mg/ml triamcinolone acetonide treatment. The apoptosis percentage for TA, which was the apoptotic TM cell number divided by the total TM cell number, was adjusted by benzyl alcohol. The asterisk indicates that significantly increased apoptotic cells were observed with both TA treatment on days 3 and 5 compared to 12 h. The sharp (hash mark) means that when compared to 0.1 mg/ml TA treatment, the number of the apoptotic TM cells was significantly increased with 1 mg/ml TA treatment on day 5.
