Microanatomy of the optic canal.
The human optic canal, an intricate anatomical structure with several normal variations, was studied in 83 individual cadaver specimens. The landmarks and dimensions of the adjacent structures were noted and correlated with surgical exposure of the area. The transorbital-ethmoidal route for extracranial decompression of the optic canal was also studied.
