A 65-year-old non-diabetic woman sustained injuries in a traffic accident. On arrival at our hospital, she was fully conscious. There was right-sided blepharoptosis, and on passive opening of the eyes, the right eye was abducted, with adductor paralysis. The pupils were 5 mm (right) and 3 mm (left) in size ; the left pupil showed normal light reflex, while the right did not react to direct/indirect light. Head CT/MRI revealed no abnormalities. A diagnosis of isolated oculomotor nerve palsy associated with mild head injury was made, and conservative treatment was selected. By 1 year after the injury, the patient became capable of unassisted opening of the right eye and unimpaired adduction, although the upward and downward movements remained impaired. The pupils became 4 mm (right) and 3 mm (left) in size. Traumatic isolated oculomotor nerve palsy associated with mild head injury without intracranial injury shows the potential for improvement of the eye movements to the extent that the patient can carry out his/her normal daily living activities.
