Is multifocal ERG a reliable index of macular function after triamcinolone acetonide injection in diffuse diabetic macular edema?

Abstract

The positive effect of IVTA injection in DDME is reversible until the sixth month. Monitoring of the improvement in visual function by mfERG is violated possibly by irreversible macular dysfunction due to long duration of macular edema and primary neurophysiologic effects of diabetes on the retina.
