Abstract
The present authors have experienced several cases in whom method of opening optic fascicular bon canal was carried out inorder to improve eye-sight following injury of the optic. foramen a blow on the head. Although there was no improvement in 2 cases, one case showed. slight improvement. It is believed that this method is effective when there is compression or atrophy of the optic nerve caused by bone fragment or hemorrhage. Since such a diagnosis is. extremely difficult, this operation should be carried out immediately if injury of the optic foramen can be confirmed.
