Introduction: The visual evoked potential is suggested to be a sensitive indicator of functional changes in the visual processing pathway. Visually evoked potentials have previously been reported to be affected in diabetes. Materials and Methods: The equipment consisted of a Nicolet 1000 clinical averager, Nicolet HGA 200A amplifier and Nicolet N/C 1015 visual stimulator. The pattern check sizes used were 10 and 40 minute arc with contrast of 80 and 40% for each check size. The non-insulin dependent diabetes (NIDD) patients were recruited from the University of Bradford Diabetic Retinopathy Screening Programme. The non-diabetic control group was recruited from patients, partners and members of the University in departments other than Optometry. The age and duration of diabetes for all subject groups were normally distributed. Results: Correlation coefficients between the duration of diabetes and VEP latencies of the three diabetic groups individually and the diabetics as a group all failed to reach significance, reflecting the large variance within the data. Similarly, correlation coefficients between the duration of diabetes and VEP amplitudes of the three diabetic groups individually and the diabetics as a group all failed to reach significance, reflecting the large variance within the data. Conclusion: The visual evoked potential latency and amplitude seemed to be poor indicators of the duration and severity of diabetic retinopathy in diabetes.
