Abstract

Three paediatric patients post-mild traumatic brain injury (mTBI, also known as concussion) developed saccadic intrusions, which are irregular, involuntary saccades that interrupt fixation. Each patient presented to a mTBI clinic months post-injury, complaining of headaches, difficulty concentrating, and dizziness. Written informed consent from parents was obtained for use of these cases.

Keywords: concussion; paediatrics; saccades; vision therapy.

Figure 1.
Patient 1, 0.2 Hz horizontal smooth pursuit trace. Black line is the location of the target (UP/Increase in degree = Rightward, DOWN/Decrease in degree = Left-ward). Blue trace is the eye fixation location of the patient.

Figure 2.
Patient 2, 0.1 Hz horizontal smooth pursuit trace before gabapentin treatment
Figure 3.
Figure 3.
Patient 2, 0.1 Hz horizontal smooth pursuit trace after two months of gabapentin. Notice that the trace is still not entirely smooth but is more accurate and with smaller amplitude deviations than before gabapentin in Figure 2.
Figure 4.
Figure 4.
Patient 3, 0.1 Hz horizontal smooth pursuit trace (UP/Increase in degree = Upward, DOWN/Decrease in degree = Downward). Notice that there are fewer deviations of greater amplitude than the traces of Patients 1 and 2.
