ABSTRACT
<p><b>OBJECTIVE</b>To investigate the characteristics of multifocal electroretinograms (mf-ERG) of different phases in diabetic retinopathy (DR) and its clinical significance.</p><p><b>METHODS</b>Multifocal electroretinograms in patients with DR (I - II stage) were tested with VERIS IV system.</p><p><b>RESULTS</b>In I - II stage, the absolute values of N1, P1 and N2 response densities, and the N1-P1 and P1-N2 response densities were attenuated is a field of about 45 degrees in diameter.</p><p><b>CONCLUSION</b>As a new objective and quantitative examination for spatial visual function, multifocal electroretinograms may be valuable in the diagnosis of diabetic retinopathy.</p>
