Mean values of IL-17 concentrations in tears of each patient group compared to the Graft-versus-host disease patients. The mean IL-17 concentration of graft-versus-host disease patients was significantly higher than those of dry eye syndrome without systemic disease patients, Stevens-Johnson syndrome and Sjögren syndrome patients (Mann-Whitney U test). GVHD, graft-versus-host disease; DES, dry eye syndrome without systemic disease; SJS, Stevens-Johnson syndrome; Sjogren, Sjögren syndrome.
