Table 1 Baseline characteristics and CT/MRI findings of five patients with traumatic brain injury and unilateral third nerve injury

From: Infrared pupillometry, the Neurological Pupil index and unilateral pupillary dilation after traumatic brain injury: implications for treatment paradigms

Patient # Trauma mechanism Age/sex GCS Initial CT trauma findings relative to the injured third nerve CT/MRI abnormalities in the region of the affected third nerve Surgical intervention Follow- up time (months) Pupillary function outcome
1 Bicycle versus automobile 43/F 5 Contralateral frontal contusion MRI: enhancement of cisternal portion None 15 Normal: R pupil function returns slowly
2 Ground level fall 67/M 15 Perimesencephalic bleed CT: blood adjacent to the third nerve None 2 Normal: R pupil function returns rapidly
3 Bicycle accident 12/M 3 Contralateral BG hemorrhage MRI: enhancement of cisternal portion Left sided evacuation of BG bleed 15 Abnormal: R pupil dilated and unresponsive
4 Thrown from horse 35/F 13 None MRI: enhancement of cisternal portion None 4 Abnormal: L pupil anisocoria, dilated, and unresponsive
5 Motorcycle accident 59/F 3 R CCF, orbital rims fractured CT: CCF Endovascular obliteration of CCF 2 Abnormal: R pupil dilated and unresponsive
  1. Each patient recovered normally and was assessed as a Glasgow Outcome Score of 5.
  2. BG basal ganglia, CCF carotid cavernous fistula, CT computed tomography, GCS Glasgow Coma Score, L left, MRI magnetic resonance imaging, R right.
