Finite element modeling of optic chiasmal compression

Wang, X; Neely, AJ; McIlwaine, Gawn G.; Tahtali, M; Lillicrap, Thomas; Lueck, Christian

Description

Background: The precise mechanism of bitemporal hemi-anopia is still not clear. Our study investigated the mechanism of bitemporal hemianopia by studying the biomechanics of chiasmal compression caused by a pitui-tary tumor growing below the optic chiasm.Methods: Chiasmal compression and nerve fiber interaction in the chiasm were simulated numerically using finite element modeling software. Detailed mechanical strain distributions in the chiasm were obtained to help understand the mechanical...[Show more]
