Curative effect of intravitreal injection of conbercept on macular edema in different types of OCT diabetes mellitus

AIM: To observe the efficacy of intravitreal injection of conbercept for diabetic macular edema(DME)with different patterns of optical coherence tomography(OCT).METHODS: A total of 96 patients(96 eyes)with DME were classified as diffuse retinal thickening(DRT group, 35 eyes), cystoid macular edema(CME group, 33 eyes)and serous retinal detachment(SRD group, 28 eyes)according to the OCT. All patients were treated with intravitreal injection of 0.5mg(0.05mL)conbercept. The changes of best corrected visual acuity(BCVA), central foveal thickness(CFT), the injection times and vision improves eyes were compared between three groups after 1,3,6mo treatment.RESULTS: After 6mo follow up, the BCVA of the three groups showed a significant downward trend(Ftime=205.880, Ptime
