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.
