Venn diagram showing the differential cytokine expression in the DME and high-risk proliferative diabetic retinopathy (Hr-PDR) groups. The enlisted cytokines showed a >2-fold increase (P<0.05) >50% of the cases compared to the no-DR group. DME, diabetic macular oedema; GCSF, granulocyte colony stimulating factor; Hr-PDR, high-risk proliferative diabetic retinopathy; IL1b, interleukin 1b; IL1RA, interleukin 1 receptor antagonist; IL6, 7, 8, 10, 12p70, 13, interleukin 6, 7, 8, 10, 12p70, 13; IP10, interferon gamma inducible protein 10; MCP1, monocyte chemotactic protein 1; MIP1a &1b, macrophage inflammatory protein 1a & 1b; PDGF, platelet-derived growth factor; TNFa, tumour necrosis factor alpha; VEGF, vascular endothelial growth factor.
