METHODS

Fourteen cases were treated by transnasal endoscopic sphenoethmoidal optic canal decompression in clinic.

RESULTS

Nine of them had their visual acuity improved from NLP, HM, FC/50 cm, HM, NLP, LP, NLP, HM, NLP to 0.2, 0.3, 0.3(+2), 0.4, 0.06, 0.3, 0.1, 0.7, 0.12 after the operation. The clinical anatomy, attentions during operation, merits of operative approaches were discussed.
