01). The mfERG showed significant differences in the amplitude. The average amplitude was 35 ± 12 nv/deg2 in the normals and 29 ± 11 nv/deg2 in the prediabetics (p = 0.003). A weak positive correlation was noted between the mfERG and vascular parameters in the prediabetic group. Conclusions The prediabetic stage reveals earliest functional neuronal changes in the retina. The neuronal function seems to be affected much earlier than clinically appreciable structural changes in the ganglion cell complex and precedes vascular changes in t
