Figure 5. The concentrations of the pro-inflammatory cytokines IL-1β and TNF-α were quantified in the ocular tissue of all experimental groups. Data are presented as the mean ± SD (n = 6). Statistical significance is indicated as follows: double asterisks (p < 0.01) and triple asterisks (*p < 0.001) denote a significant difference compared to the control (C) group; the symbols #, +, and ^ denote significant differences compared to the untreated diabetic (D) group at #p < 0.05, ##p < 0.01, +p < 0.05, ++p < 0.01, ^p < 0.05, ^^p < 0.01, and ^^^p < 0.001.
