Objective: To explore the feasibility of applying flash visual evoked potentials (FVEPs) for visual function test newborns and infants and bring out the consultable laboratory values of FVEPs. The technology of FVEP could be used as diagnostic tests for those who failed the screening and the infants who were cared for in the NICU.
Methods: 41 normal neonates (<or= 4 days) and 18 normal infants (<or= 5 months) were tested with FVEP by Nicolet Viking-IV model evoked potentials apparatus.
Results: Get the normal reference range of FVEPs latency in both groups and the consulting value of the difference between the left and right eyes. It has been observed from the paper that the latency of FVEPs has the tendency to shorten with the age increasing. It also shows that there are extreme significant changes of FVEPs (P < 0.05) by different frequency of stimulating light.
Conclusion: The latency of FVEPs P1 is steady and could be applied to newborns-infants visual function test. While, the references of FVEPs according to different age group should be taken into account when we using this measure in clinic.
