Ten cases of primary oculomotor nerve palsy due to head injury are presented. All ten patients had a dilated, non reactive pupil. Seven had complete oculomotor palsy. ⋯ The prognoses of blepharoptosis, external ophthalmoplegia and internal ophthalmoplegia were analyzed separately. The recovery rates were 78%, 44% and 20%, respectively, the internal ophthalmoplegia showing poorest recovery. We discuss the mechanism of direct injury to the oculomotor nerve.
