From: Keratoconus patients exhibit a distinct ocular surface immune cell and inflammatory profile
Tear fluid secreted factors level in KC patients: The graphs indicate the concentration of granzyme-B (a), perforin (b), IgE (c), sFasL (d) and β2 microgloublin (e) in the tear fluid of subjects with different grades of KC. Ctrls—Controls; All-KC—all the grades of keratoconus combined; FFKC—Forme fruste keratoconus; IgE—immunoglobulin E; sFasL—soluble Fas ligand; SEM—standard error of the mean; Controls (20 eyes), All-KC (41 eyes), FFKC (6 eyes), grade 1 KC (6 eyes), grade 2 KC (6 eyes), grade 3 or 4 (23 eyes); Bar graphs represent Mean ± SEM; *P < 0.05, **P < 0.01, Mann–Whitney test.
