Abstract | Background. Optic neuritis (ON) is rarely confirmed in children, but often it is suspected. Considering that there are differences in the clinical features of ON in children we investigated the value of electrophysiology in uncertain ON cases. Therefore we compared PERG and VEP characteristics from children with suspected ON and definite ON to healthy children. Methods. Pattern-reversal full-field (0-16 degrees) stimulation was used for simultaneous recording of VEP and PERG activity. VEP was also recorded to right and left half-field stimulation. Results. Children with suspected ON had all normal PERG and 3/14 (21%) abnormal VEP. Children with definite ON (four) had normal PERG and abnormal VEP. Conclusions. Our results confirm that definite ON in children is associated with abnormal VEP. Also, ON suspects whose VEPs exceeded normal limits could be viewed as electrophysiological evidence of ON. | |
