• Note (General): application/pdf; Purpose : To determine the effectiveness of intravitreal aflibercept (IVA) on the retinal function in eyes with diabetic macular edema (DME).Methods : Twenty-five eyes of 25 patients with DME were treated with three consecutive monthly IVA injections. The retinal sensitivities (RS) within the central 10°were determined by microperimetry (MP). The central subfield macular thickness (CMT) was determined by optical coherence tomography, and the implicit times (IT) and amplitudes (Amp) of the flicker electroretinograms (ERGs) were determined from the ERGs elicited and recorded by the RETeval. The number of microaneurysms (MAs) was counted in the fundus photographs. The assessments were made before the IVA injections (pre-IVA) and one week after the IVA injections (post-IVA). The correlations between the reduction ratio of the MA numbers/CMT and RS/IT/Amp were evaluated.Results : The mean RS improved from 19.9 ± 5.9 dB to 22.0 ± 5.8dB, the CMT decreased from 485.7 ± 90.6 µm to 376.9 ± 81.6 µm, and the number of MAs decreased from 49.6 ± 33.2 to 24.8 ± 18.1 after the IVA injection (all P < 0.01). The changes in the IT from 31.3 ± 3.3 ms to 31.5 ± 3.1 ms and the Amp from 12.2 ± 5.5 µV to 11.3 ± 6.1µV post-IVA were not significant. A significant correlation was found between the relative changes in the CMT and RS (r = -0.43; P = 0.02), the MAs and RS (r = -0.38; P = 0.03). No significant correlation was observed between the relative changes of the number of MAs/CMT and IT/Amp.Conclusions : IVA can improve both central retinal function and anatomical conformation.; 本文/Department of Ophthalmology, Mie University Graduate School of Medicine, Mie, Japan; 10p
