Levels of Inflammatory Cytokines IL-1β, IL-6, IL-8, IL-17A, and TNF-α in Aqueous Humour of Patients with Diabetic Retinopathy

Figure 1

Histogram of inflammatory cytokine levels in aqueous humour. (a) Histogram of each cytokine in the 5-year DR group and 5-year DM group. All tested cytokines were higher in the 5-year DR group (all ). (b) Histogram of each cytokine in the 10-year DR group and 10-year DM group. All tested cytokines were higher in the 10-year DR group (all ). (c) Histogram of each cytokine in the 5-year PDR group and 5-year NPDR group. All tested cytokines were higher in the 5-year PDR group (all ). (d) Histogram of each cytokine in the 10-year PDR group and 10-year NPDR group. All tested cytokines were higher in the 10-year PDR group (all ). (e) Histogram of each cytokine in the 5-year DR group and 10-year DR group. All tested cytokines were higher in the 5-year DR group (all ). (f) Histogram of each cytokine in the 5-year DM group and 10-year DM group. There were no statistical differences in all tested cytokines in these two groups (all ).
