Abstract:
Aim of the research was to outline signs of traumatic optic neuropathy (TON)
caused by mild head trauma(mTBI) in school-aged children.
Methods: Forty eight patients with persisting visual symptoms after mild brain
injury have been examined. Visual evoked potentials examination has been
undergone in order to establish visual pathways alteration.
Results: VEP exam revealed a possible TON on both eyes in 61,1% patients and a
unilateral TON in 16,1% patients after mTBI. This values have been reported as being
referred to an increased latency of the N2 wave in 55,6% for the right eye and 66,6%
for the left eye, increased latency of the P wave in 55,7% for the right eye and 66,7%
for the left eye and increased latency of the N3 wave in 16,7% for the right eye and
33,3% for the left eye. Also a decreased amplitude of the P wave has been
determined for the right eye in 16,7% patients and for the left eye 33,3% patients.
Conclusions: Our research has been an attempt to outline the features of traumatic
optic neuropathy that may occur after mTBI. Since the ophthalmoscopy findings
often come with a clear a picture it is important to determine whether there are
present signs of visual pathway alteration.
