The effect of steroids in combination with optic nerve decompression surgery in traumatic optic neuropathy.

Objective: Traumatic optic neuropathy (TON) is an important cause of severe visual impairment following blunt or penetrating head trauma. Treatment options include steroids, decompression, or both. Studies have failed to show a clear benefit for either steroids or surgery or a combined therapy. This study describes the visual outcome in surgically managed patients with or without steroid treatment.

Methods: Retrospective analysis. Methods: In a retrospective chart review we included patients (n = 42) with TON who were managed with optic nerve decompression surgery with or without steroids. Comparison of initial and final visual acuity was the primary outcome parameter.

Results: In 42 consecutive patients, steroids were used in 21 cases (50%). Ten patients received a high-dose systemic regimen of more than 500 mg methylprednisolone initial dose, and 11 patients were treated with a lower dose. The overall visual improvement rate was 33%, no change was noted in 50%, and no outcome data were available in 17%. The visual improvement rate of patients treated with decompression surgery and steroids was lower (29%, 6 of 21) than those treated with surgery alone (53%, 8 of 15). Comparing both groups, additional steroids had no beneficial effect on the visual outcome (P = .97). There was no case with a deterioration of visual function due to therapy.

Conclusions: In patients with traumatic optic neuropathy who were treated with optic nerve decompression surgery, steroids had no beneficial effect on the visual outcome. Methods: 2c.
