Figure 2. Clinical evaluation and TLR4⁺ and CD163⁺ cells in the iris during the course of EIU. A: The clinical score of EIU and inflammation reached their maximum at 24 h. B: The density of TLR4⁺ cells in the rat iris had increased greatly 12 h after injection. C: There are no obvious changes in the density of CD163⁺ cells in the rat iris within 24 h, but the density had increased 48 h after injection. D: Percentage of round-pleiomorphic CD163⁺ cells in the rat iris during the course of EIU is shown in the chart. Significant differences compared with the controls at a level of p<0.001 are shown by asterisks.
