Abstract
To determine characteristics of diabetic macular edema patients with serous retinal detachment (SRD).We classified naïve diabetic macular edema (DME) patients with or without SRD, and compared their baseline characteristics; intravitreal bevacizumab (IVB) responsiveness; aqueous concentrations of IL (interleukin)-1β, -2, -8, -10, -17, placental growth factor (PlGF), and vascular endothelial growth factor (VEGF). In addition, factors associated with the existence of SRD were identified.Of the 64 DME patients, 14 had SRD. The average levels of aqueous VEGF and PlGF were significantly higher in the SRD group than in the control group (P = .022 and P = .041, respectively). The best-corrected visual acuity (BCVA) and central subfield thickness (CST) did not differ significantly between the 2 groups at baseline or after 3 consecutive monthly IVBs. In multivariate logistic regression analysis, the level of aqueous VEGF was the only factor associated with the existence of SRD (odds ratio: 1.03; P = .038).Rather than aqueous inflammatory cytokines, levels of aqueous VEGFs were associated with the occurrence of SRD in DME patients. In terms of prognosis, the existence of SRD was not related with BCVA or CST changes.
