Objective To investigate the clinical factors which improved the postoperative vision in patients with meningeal tumor of sellar region invaded the optic canal. Methods Clinical data was collected from medical records of patient with meningeal tumors invaded optic canal from Jan. 2010 to Oct. 2016.A multiple factor analysis with logistic regression method was used to analyze these data. Results There were 55 cases included in the study. Vision was improved in 26 cases including 15 of 17 cases with early epidual optic canal decompression, 5 of 9 cases with Later optic canal decompression and 6 of 29 cases with curettage of optic canal tumor. A univariate analysis showed that resection grade,tumor adhesion and early epidural optic canal decompression were associated with visual improvement. Regression analysis showed that early epidural optic canal decompression was the only factor which could improve postoperative vision. Conclusion Early epidural optic canal decompression should be a good choice to improve the postoperative vision of meningeal tumors of sellar region invaded the optic canal.
