Efficiency analysis by mfERG and OCT of intravitreal injection with ranibizumab on diabetic macular edema

AIM: To analyze the clinical efficacy of intravitreal injection of ranibizumab (IVR) on diabetic macular edema (DME) with multifocal electroretinography (mfERG) and optical coherence tomography (OCT). METHODS: A total of 41 patients (41 eyes) with DME were treated with IVR. The best corrected visual acuity (BCVA), mfERG results, and OCT were analyzed to compare to the baselines at 1wk, 1, and 3mo after operation. RESULTS: The BCVA was significantly improved in all eyes at each time point (P
