title: The use of a pinhole aperture during the recording of pattern reversal visual evoked potentials.
abstract: In young children, mentally retarded persons or in malingering persons, determining the optimal refraction is not always evident. Because of the importance of this optimal refraction during the recording of pattern-reversal visual evoked potentials, we tried in this study to overcome these refraction errors by the use of a pinhole.
