Structural analyses of the anterior visual pathway in compressive neuropathy

Pituitary tumors are one of the most common types of brain tumors that can cause progressive blindness. Due to the indolent nature of the vision loss, these patients are often misdiagnosed which can turn a reversible cause of visual dysfunction into a permanent life-altering disability. Adding to the difficulty in treating patients with pituitary tumors is the lack of validated preoperative predictors of visual outcome. The purpose of this study was to determine whether structural changes in the anterior visual pathway differ in patients with good versus poor visual recovery.
