Diabetes takes a leading place among the causes of blindness. One hundred three patients with type 1 diabetes mellitus (DM) aged from 18 to 45 years were examined with varying severity of visual disorders. Disease duration was from one year to 10 years. A neurophysiological examination was performed using visual evoked potentials on black-and-white (BW) and color (red-yellow (RY) and green-black (GBk))сhanging chess pattern(CCP).The results obtained in terms ofVEPindices made it possible to note that in all patients of the study group conduction disturbances were detected in the visual fibers of the analyzer, namely, an increase in the peak latency (PL) of P100 and a decrease in the amplitude of the wave (WA) N75-P100 with an earlier prevalence of disorders in the color-changing CCP relative toBW. The study has shown that in type 1 DMcolor vision as the most subtle structural element of the VAis primarily affected.
