Variation in the anatomy of the normal human optic chiasm: an MRI study

Bosler, Nicholas; Ashton, David; Neely, Andrew; Lueck, Christian


Abstract Background: Compression of the optic chiasm typically leads to bitemporal hemianopia. This implies that decussating nasal fibers are selectively affected, but the precise mechanism is unclear. Stress on nasal fibers has been investigated using finite element modeling but requires accurate anatomical data to generate a meaningful output. The precise shape of the chiasm is unclear: A recent photomicrographic study suggested that nasal fibers decussate paracentrally and run parallel to...[Show more]
