Abstract
PURPOSE: To compare aqueous angiogenic and inflammatory cytokine concentrations in different patterns of diabetic macular edema (DME) based on optical coherence tomography (OCT). METHODS: This prospective study was conducted between July 1, 2015, and March 31, 2016, for 9 months. Aqueous samples were obtained from 52 consecutive DME patients and 16 controls. DME patients were divided according to OCT patterns into diffuse retinal thickening (DRT; n = 17), cystoid macular edema (CME; n = 20) and serous retinal detachment (SRD; n = 15) groups. Interleukin (IL)-6, IL-8, vascular endothelial growth factor (VEGF) and tumor necrosis factor alpha (TNF-α) levels were measured by RayBio(R) Human ELISA Kit. RESULTS: IL-6, IL-8 and VEGF levels differed significantly between three DME groups (p < 0.001 in all cases), but the differences in TNF-α levels were not significant (p = 0.226). VEGF and IL-6 levels correlated with central foveal thickness in DRT and SRD groups, respectively. CONCLUSION: Aqueous cytokine levels vary with different morphological patterns of DME though the role of TNF-α needs to be studied further, and both anti-angiogenic and anti-inflammatory agents are required simultaneously for treatment of DME.
