INTRODUCTION: The recording of visual evoked potentials is very useful to determine visual lesions that in diabetes mellitus are expressed as diabetic retinopathy and damage of the optic nerve. OBJECTIVES: To characterize the involvement of the visual analyzer in diabetes mellitus through determining the damage to the visual path on the basis of visual evoked potentials; and also to correlate the clinical state of the visual path, the metabolic control and the length of the disease with the electrophysiological alteration of diabetes mellitus. METHODS: A study on the visual evoked potentials in type I and II diabetes mellitus under 15 years of evolution was conducted together with a cross-sectional analytical research of cases (n = 32) and healthy controls (n = 16).Latency and P₁₀₀ amplitude of VEP in both eyes were ascertained and the retina was clinically studied to determine related diseases. RESULTS: Latency P₁₀₀ 104,68 ± 4,28 in GE y 97,5 ± 3,71 in GC (p = 0,089), amplitude P₁₀₀ 10,84 ± 2,45 in GE and 8,02 ±1,70 in GC (p = 0,673)

Keywords : evoked potentials; diabetic retinopathy; neurophysiology.
