Traumatic isolated divisional oculomotor nerve palsy has not been reported following mild head injury. We present an interesting case of a 10-year-old male boy who presented with right-sided ptosis, upgaze palsy, and horizontal nystagmus following a mild head trauma. Magnetic resonance imaging showed right superior rectus muscle atrophy. After observing for 6 months, right inferior rectus recession was done. The abnormal head posture and diplopia got corrected, but nystagmus persisted, although with appreciably decreased amplitude. We here report a rare case of an isolated superior divisional oculomotor nerve palsy following mild head trauma. Nystagmus accompanying a divisional oculomotor nerve palsy has never been reported before, making this case more unique. A critical step-wise approach to the case with possible mechanisms are discussed.
