There are numerous causes for cranial nerve injury that include head trauma or other lesions. Few studies regarding cranial nerve injury following mild head trauma (GCS: 14 – 15) exist in the literature. The oculomotor nerve is a somatic and visceral motor nerve. When it is completely injured the result is ptosis, pupils that are non-reactive to light and a lack of eye movement. We report the case of a completely isolated oculomotor nerve palsy associated with minor head injury.
