Transient bilateral internuclear ophthalmoplegia after minor head-trauma

Abstract

Following minor occipital head-trauma, a six-year-old boy developed bilateral internuclear ophthalmoplegia (INO) as the only neurological sign. After having excluded all other possible aetiological causes by careful examination, including magnetic resonance imaging, the symptoms eventually were attributed to the trauma. The course of the INO was documented by electro-oculography. A saccades-training programme specially adapted to the boy's age was performed, and complete remission of the oculomotor symptoms occurred after one year.
