Clinical outcome of mild head injury with isolated oculomotor nerve palsy.

Isolated oculomotor nerve palsy after mild head injury is rare. Only a few case reports have described the clinical presentation of these patients, and clinical and functional outcome have not been discussed in depth. The outcome of 10 patients with mild head injury in whom imaging studies ruled out other possible causes of oculomotor palsy was assessed during follow-up using the Glasgow Outcome Scale-Extended (GOSE). We suggest that limited eye movement is a major factor that negatively affects functional status after mild head injury.
