Multifocal electroretinogram in clinically significant diabetic macular edema.
OBJECTIVE
To explore the multifocal electroretinogram in patients with nonproliferative diabetic retinopathy with clinically-significant macular edema.


METHODS
Forty-one eyes with clinically significant macular edema were tested. The latencies and amplitudes of average responses of 5 eccentric rings from 0 to 26 degrees relative to the fixation point were compared with normal values obtained from 13 nondiabetic subjects.


RESULTS
Local electroretinogram responses were significantly delayed and decreased in amplitude in patients with clinically-significant macular edema.


CONCLUSIONS
Multifocal electroretinogram can be used to quantify the visual function in clinically significant macular edema.
