Amount of dendritiform cells (DCs) per square millimetre. In the subepithelial corneas of patients with herpetic anterior uveitis (HAU) vs. Fuchs uveitis syndrome. (A) Significantly, more DCs were present in the affected eyes of HAU compared with FUS (*p < 0.0001 Mann Whitney U test). (B) Both eyes of patients with herpetic uveitis showed increased DCs in their corneas, indicating a co-response of the fellow eye. DCs in the affected eyes of FUS patients were moderately elevated but not in the unaffected eyes.
