| Abstract |
|
We compared the result of 6 patients[group A]treated with high dose steroid only with the result of 14 patients[group B]treated with optic canal decompression after at least 24 hours of high dose steroid therapy without improvement. 4 of 6 patients[66%]in group A and 7 of 14 patients[50%]in group B improved in visual acuity.But 1 of 6 patients[17%] in group A and 6 of 14 patients[43%]in group B had marked improvement in visual function[above 0.02].Of 5 patients with optic canal fracture in orbit CT in group B, all had improved visual function and 4 had marked improvement in visual function. If CT demonstrates bony fragments impinging on intracanalicular optic nerve, or if vision deteriorates or fails to improve during the first 24 hours of high dose steroid and initial visual acuity is no light perception, optic canal decompression is considered effective and valid treatment modality in TON. |
