Electrofunctional investigations of the optic nerve in diabetes.

After a brief introduction of the principal reports of ocular electrophysiology in diabetic diseases, are described the results of the registration of the visually evoked potential (VEP) and oscillatory potential (OP) in two groups of young patients affected by Type I diabetes. In both groups the VEP latencies increased with respect to the controls and such increase seems evident whether in the group with altered PO or in that of younger patients with PO still normal.
