Figure 2. Proliferation of human trabecular meshwork cells in the presence of various concentrations of triamcinolone acetonide and over a five-day treatment period. A: The asterisk indicates that both concentrations of TA caused significant reduction in the number of TM cells as early as day 1 and across 5 days of the treatment period (p<0.01). The double asterisk means that there was a significant difference in the number of TM cells between 0.025% and 0.0025% benzyl alcohol in the culture (p<0.005). B: After eliminating the benzyl alcohol effect, there was no significant difference in cell proliferation between 0.1 mg/ml TA and 1 mg/ml TA one day after treatment (p=0.058) while a significant difference in cell proliferation was observed between the two concentrations of TA treatment on day 3 (p=0.003) and on day 5 (p<0.0005).
