Numbers of dendritic cells and vessels (per mm²) in the central area of the cornea.

A)Mann-Whitney U test, *p<0.05. There were statistically significant differences in the numbers of langerin+ DCs, DC-SIGN+ DCs, CD83+ DCs, and lymphatic vessels between infected and non-infected cases. Herpetic keratitis cases were excluded from the statistical analyses. This is because they were all in chronic states without neutrophil infiltration; therefore, infections could not be defined.
