[Relationship between operative time and therapeutic effectiveness after the optic nerve injuries].

OBJECTIVE

To understand the relationship between the operative opportunity and effectiveness in the optic nerve injuries.

METHOD: Twenty-three cases with optic nerve injuries were undertaken optic canal decompression.

RESULT: The visual acuity in 13 cases were improved after the operation, and progressed about 0.233 averagely. The average time from injuries to operations was (12.90 +/- 16.77) d (3-22 d) in ineffective group. 7 cases of hypoactivity of eyeball recovered in 8 cases.

CONCLUSION

The optic nerve decompression should be done after the patients were treated with megadose of steroid for 48 hours and did not recover. The time had better be no more than 7 days.
