Abstract


AIM: Traumatic optic neuropathy is a devastating complications of head injury. The improvement in vision after treatment has a significant impact
on the prognosis. This study analyses the association between pre interventional visual evoked potential and the post interventional visual outcome.
Methods: In this study 56 patients with mild and moderate head injury with associated optic nerve injury were included. Patients with pre existing
optic nerve disease where excluded. Clinical assessment of the patient’s vision and visual evoked potential were recorded. Patients were treated by
medical and surgical methods accordingly. Statistical analysis was done using IBMSPSS software.
Results: Patients with abnormal waves in VEP showed significant improvement in vision. Patients who had absent waves in VEP showed poor
recovery in vision.
Conclusion: Visual evoked potential is an excellent tool to assess the visual outcome in patients with optic nerve injury in the setting of traumatic
brain injury
