Abstract

BackgroundTo investigate the effectiveness of vitrectomy for diffuse diabetic macular edema (DDME) and its dependence on optical coherence tomography (OCT) findings.MethodsThe records of 65 patients and 81 eyes who received vitrectomy for DDME and followed up for at least 6 months were retrospectively reviewed. All eyes were classified according to their morphological characteristics on OCT including sponge-like diffuse retinal thickening (SDRT: n = 13), cystoid macular edema (CME: n = 42), serous retinal detachment (SRD: n = 13), and the combination of all morphological characteristics (FULL: n = 13). The best-corrected visual acuity (BCVA) and spectral domain OCT were investigated preoperatively and at 1, 3, and 6 months postoperatively.ResultsAt six months after surgery, BCVA in logMAR units was significantly improved in all groups except the SDRT group. The improvement was −0.04 ± 0.20 in the SDRT group (P = 0.504), −0.16 ± 0.24 in the CME group (P < 0.01), −0.32 ± 0.32 in the SRD group (P < 0.01), and −0.26 ± 0.19 in the FULL group (P < 0.01), and significantly better in eyes with subretinal fluid (SRF; the SRD and FULL groups) than in eyes without SRF (the SDRT and CME groups, P = 0.003).ConclusionsVitrectomy can be a useful treatment option for DDME, particularly for eyes with SRF.
