Correlation of MRI Findings With Patterns of Visual Field Loss in Patients With Pituitary Tumors

Kane, Emily; Ashton, David; Reid, Kate; Neely, Andrew; Lueck, Christian

Description

Background: Compression of the optic chiasm by pituitary tumors typically results in bitemporal hemianopia, implying that nasal retinal fibers are preferentially damaged. The reason for this is not clear. One theory suggests that nasal fibers are selectively vulnerable simply because they cross each other. This study investigated the “crossing theory” by correlating visual field (VF) loss with chiasmal elevation and with the degree of eccentric compression on MRI scans. Methods: Our hospital...[Show more]
