Figure 5. The expression of interleukin-6 in the aqueous humor and serum at different time points (expressed as the mean μg/l±SD). The concentration of interleukin-6 in the aqueous humor was consistently much higher than in the serum. The interleukin-6 concentration in the aqueous humor rapidly increased in the first 4 h, reached a peak at 16 h, and returned to the original concentration after 48 h.
