A new method to measure the pattern reversal visual evoked response in infants and young children.

A modification was made of the conventional method of recording the pattern reversal visual evoked response (VER) to study the VER in infants and young children. Application of this modified method to 36 patients, the majority of them with retinopathy of prematurity, showed that this method is useful in the evaluation of the visual function in infants and young children, and also in a 12-year-old mentally retarded girl.
