Introduction. The aim of the study was to assess the impact power of mild traumatic brain injury (mTBI) in children of school age on the functional integrity of the visual pathways. Material and methods. Research has been undergone on 25 in- patients with mTBI associated to visual disturbances such as: blurred vision, flashing lights, transient diplopia, alterations in color perception. The examination has been performed using a pattern VEP model, in which the light and dark elements of the model were organized to form a chessboard. Both latency and amplitude of the P wave have been assessed as a primary goal, although a special attention was referred to the other two negative components of the potential (N140 and N70). Normal mean value for P wave latency given by the laboratory was the interval of 115-125 ms. Results showed that 69.56% out of all patients had a decreased P wave latency for the right eye and 78.26% for the left eye. The latency interval for N2 wave has been established mostly for the 60-80ms: 91.3% for the right eye and 78.26% for the left eye. As for the N3 wave the values have been ranged mostly in the 130-160ms interval: 91.13% for the right eye and 73.98% for the left eye. Conclusions. Assessment of visual evoked potentials in the acute stage of mTBI may reveal possible complications and impose treatment correction, including drug therapy or interventional measures.
