title: The effect of iron supplementation on visual-evoked potentials in infants with iron-deficiency anemia.
abstract: Flash visual-evoked potentials were studied in 20 infants with iron-deficiency anemia to determine the effect of iron deficiency on visual function by using visual-evoked potentials in this type of anemia. After iron therapy for 12 weeks, visual-evoked potentials were retested in these otherwise healthy infants. All infants showed an excellent hematological response to iron therapy. Post-treatment visual-evoked potential N2 latencies (negative deflections) decreased significantly compared to the pre-treatment values (p < 0.05). These results suggest that iron-deficiency anemia causes subclinical visual impairment, and visual-evoked potentials may be a useful non-invasive means of detecting subtle effects of nutritional deficiencies and monitoring the nutritional status of infants.
