[Trans-ethmoidal optic nerve decompression in traumatic optic neuropathy].
To evaluate the outcome of trans-ethmoidal optic nerve decompression (TOND).


METHODS
Between November 1984 and May 1996, 35 patients with traumatic optic neuropathy (TON) underwent TOND. While 6 patients were treated with high dose corticosteroids (HDC).


RESULTS
13(37.14%) cases of 35 patients who underwent TOND showed improvement in vision. 1 (16.67%) of 6 patients who were treated with HDC showed improvement in vision. Of the 12 patients with some initial vision, 8 patients underwent TOND and 7(87.5%) patients showed improvement in vision. Another 4 patients treated with HDC, 1(25.0%) patient showed improvement in vision. Of the 29 patients who presented with no light perception, 27 patients underwent TOND and 6(22.22%) patients showed improvement in vision. 2 patients treated with HDC failed to get vision improvement.


CONCLUSIONS
TOND can improve vision in patients with TON. It is rational to perform surgical decompression early. Using of HDC before and after surgery may improve the outcome of TON. No light perception and absence of waveform on visual evoked response is not contradict, some patients may show improvement in vision.
