Visual evoked potential changes in patients with tropical pancreatic diabetes.
Visual impairment is an important complication of diabetes. There are conflicting reports on Visual Evoked Potential (VEP) changes in diabetes. P100 latency of VEP was evaluated in twenty patients with Tropical Pancreatic Diabetes (TPD) and compared with that of age and sex matched controls. There was no statistically significant difference in the P100 latency between the two groups. There was no correlation between the P100 latency and the severity of diabetes or presence of defective vision or retinopathy. The defective vision in diabetes is likely to be due to ocular causes rather than due to a defect in the central visual pathways.
