Abstract
When studying the vestibular apparatus of healthy adolescents by the method
of electronistagmography after a rotational test, 23 of 36 adolescents
revealed secondary nystagmus. Secondary nystagmus was often observed and was
more pronounced to the left. Its duration exceeded the duration of primary
nystagmus, but the intensity in terms of frequency, amplitude and speed of
the slow phase was much less. Secondary nystagmus was closely associated
with latent spontaneous nystagmus. The latter has always been accompanied by
prolonged secondary nystagmus in the same direction. Detection of prolonged
unilateral secondary nystagmus should obviously have the same significance
for issues of professional suitability as the detection of latent
spontaneous nystagmus. |
