Objective:
To evaluate the effective treatment method for the optic nerve atrophy.
Method:
Sixteen patients were diagnosed as optic nerve atrophy by examining the sight, eye base and VEP. There were no occupied lesion in the eye, nose sinus and the intracranial through the CT examination. The visual ability were become worse before the operation. This group of the patients were underwent the eye-nose-ethmoid -sphenoid approach to undergo the decompress of the optic nerve channel. During the operation, the ethmoid was removed and the sphenoid sinus was opened. When the optic nerve channel was found, more than half of it was removed. Then the whole nerve channel was opened. The sheath and the tendon of the optic nerve were opened in longitude direction. The antibiotic, hormone vessel dilation drugs were given. The changes of the visual ability, eye base and VEP between preoperation and postoperation were compared.
Result:
The visual ability and the VEP of 16 cases of the of the patients were improved. A week after the operation and three months latter examination of the eye base showed that ten of the patients got improved and six of them no change. There were no serious postoperative complication.
Conclusion:
The decompression of the optic nerve channel is the ideal method to deal with optic nerve atrophy.
