[Changes in visual evoked potential latencies following retrobulbar neuritis]

After unilateral retrobulbar neuritis, VEP latency time does not remain stable: in 7 out of 9 patients, significant changes in latency time were recorded after intervals of 15 to 35 months. In 6 of the 9 cases a reduction in latency time was observed, in 2 of them complete normalization. In one patient it increased further as compared to the initial examination. One conclusion from these findings is that optic neuritis in remission cannot be ruled out by normal VEPs.
