Abstract
Purpose: To evaluate the effect of intraviteral bevacizumab (IVB) in diabetic macular edema (DME),
using multifocal electroretinography (mfERG)
Methods: Sixty-four eyes of 32 patients with bilateral symmetric clinically significant macular edema
(CSME) were included in the study. After taking a baseline mfERG, macular photocoagulation
(MPC) was done in all eyes. After 7 days, 1.25 mg of bevacizumab was randomly injected in one
eye of each patient and the other eye assigned for sham injection. mfERG was repeated 8 weeks
after injection, and changes in visual acuity and mfERG compared in two groups.
Results: The mean best corrected visual acuities (BCVAs) at baseline were 0.55 in IVB group and
0.51 in control group and at 8th week were 0.41 and 0.53 respectively, also the amplitude and
implicit time showed significant improvement in mfERG. Significant improvement in visual acuity
and amplitude of waves of mfERG were observed compared with sham group.
Conclusion: IVB injection can augment the effect of MPC in DME and can be used as an adjunctive
treatment in these cases.
