Traumatic fracture of optic canal
is a severe injury to the optic nerve and often causes permanent visual
loss, and it is difficult to treat. This study is to evaluate the effectiveness
of decompression of optic canal by nasal endoscope. Operation of optic canal
decompression was performed on 210 cases (212 sides) with traumatic fracture of
optic canal. Clinical effectiveness was assessed based on improvement of visual
acuity. After following up for 6 months to 2 years, visual improvement with
more than one visual acuity level was observed on 101 sides (47.6%). Among
them, an excellent effect (increasing 2 levels of visual acuity) was achieved
on 72 sides (34.0%). Among 133 sides performed within 5 days of injury, 61
sides (45.9%) showed excellent effect (improved 2 levels of visual acuity). In
contrast, when operation was performed after 5 days of injury, only 11 out of
79 sides (13.9%) showed excellent effect with improvement of 2 levels of visual
acuity. And the overall effectiveness between the operations were performed within and after 5 days of injury was different significantly (P < 0.05). Therefore, endonasal endoscopic optic decompression for traumatic
optic neuropathy is an effective measure for patients with traumatic optical
canal fracture. Operation within 5 days of injury significantly increases the
success rate.
