Thirty-five patients had abnormal tear osmolarity and 40 patients were MMP-9 positive. DE indices differed between groups with abnormal and normal tear osmolarity (p less then 0.01), but not between positive and negative MMP-9 groups. There were 22 patients in group 1, 13 in group 2, 18 in group 3, and 10 in group 4. Compared to group 4, tear break-up time was shorter in groups 1 (p less then 0.01) and 2 (p = 0.02). Schirmer's test values in group 1 were lower than those in group 4 (p = 0.03). Ocular staining score was higher in group
