| Summary: |
Visual evoked potentials (VEP)
examinations based on the flash stimulation were
conducted in 41 children with meningitis (range of age:
1-776 weeks).
The results of only 14 children fall within the normal
ranges (typical waveform and typical latency of P100).
Remaining 27 children (65.9 per cent) showed abnormal
results (totally abnormal waveform in 13 children,
latency of peak P100 in 4 children, reverse polarization
of the peaks in 8 children, asymmetry of responds from
various parts of brain in 2 children).
The oldest children were those with normal VEP results (average
186 weeks). Children, who's VEP showed the smallest
change (delay of peak P100 latency) were a little
younger (average age 154 weeks). However there was no
statistical significance of the age difference between
those two groups (p = 0.8)
Group, whose VEP record revealed more disturbances
consisted of much younger patients (average 63 weeks)
and age difference was statistically significant.
Our result may suggest, that the probability of
disturbances in the visual pathway transmission is
greater in cases when the meningitis affects younger
children, than in cases of older children affected. |
