Popis: PURPOSE Evaluate interleukin and hair cortisol concentrations (HCC) in progressive keratoconus (KC) and compare them with KC stable eyes and healthy controls. Determine the correlation of these inflammatory mediators and HCC and their relationship with structural damage represented by increased corneal curvature. SETTING University of Sao Paulo. DESIGN Prospective observational comparative study. METHODS The study included 135 eyes of 75 patients.The concentrations of tear cytokines: interleukin (IL) 1B, IL6, IL8, IL10, IL12p70 and tumor necrosis factor α (TNFα) were obtained by capillary flow and measured using flow cytometer.HCC were determined from the most proximal hair segment as an index of cumulative secretion and measured by liquid chromatography mass spectrometry. RESULTS Only IL6 was increased in progressive KC tears compared with stable KC (6.59 ± 3.25 pg/ml vs. 4.72 ± 1.91pg/ml; p
