Analysis of relevant factors affecting prognosis of traumatic optic neuropathy

Objective To evaluate the relevant factors affecting prognosis of traumatic optic neuropathy. Methods Sixty-nine patients with traumatic optic neuropathy were enrolled. Multiple variable analysis was done to filter the risk factors to prognosis in traumatic optic neuropathy. Results At 3 months or more of followup,no light perception was found in 32 cases (46.4%); visual acuity were increased by≥1 lines in 33 cases (47.8%). The outcome of visual acuity was poorer in patients with the following conditions:no light perception after trauma （P=0.0031）, loss of consciousness （P=0.0262）, no pretreated common-dosage corticosteroids （P=0.0184）, and absence of VEP （P=0.0001）. Conclusion The initial visual acuity of no light perception, loss of consciousness, and no pretreated common-dosage corticosteroids were the risk factors to prognosis in traumatic optic neuropathy,and result of VEP was an effective prognosis indicator in traumatic optic neuropathy.
