Vision in the neonate (full-term and premature): preliminary result of the application of some testing methods.
Little information is available on the functionality of the visual system in neonates. Comparison was made between neonates born at full term and prematures equated for conceptional age, using two methods of investigation: the visual evoked potential (VEP) and the "forced preferential looking" (FPL). The results obtained by the FPL method indicate a greater visual acuity in premature subjects, whereas the results obtained by the VEP method point to no significant difference in implicit time between the two groups.
