To investigate the types and clinical features of neurological diseases after head trauma. Methods

From March 2010 to December 2018, a total of 177 patients were enrolled in this study. We retrospectively reviewed the clinical features of neurological ophthalmic diagnoses and frequencies, the types of head injuries, and the prognoses. Results

Cranial nerve palsy was the most common (n = 63, 35.6%), followed by traumatic optic neuropathy (n = 45, 25.4%), followed by optic disc deficiency, ipsilateral visual field defect, Nystagmus, skewing, ocular muscle paralysis between nuclei, and Terson syndrome. Neuro-ophthalmic deficits occurred in relatively strong traumas accompanied by intracranial hemorrhage or skull fracture. However, convergence insufficiency and decompensated phoria occurred in relatively weak trauma such as concussion. The prognoses of the diseases were poor ( p < 0.05) for traumatic optic neuropathies and visual field defects. The prognoses of neurological diseases were poor if accompanied by intracranial hemorrhages or skull fractures ( p < 0.05). Conclusions

After head trauma, various neuro-ophthalmic diseases can occur. The prognosis may differ depending on the type of the disease, and the strength of the trauma may affect the prognosis.
